Interactive replica of the app's OnBoarding toggle and its floating Prompt OnBoarding checklist — a demo only, to simulate the real application. Press the toggle to show or hide the checklist, exactly as the toolbar button does in the app; tick the rows and the progress, the live summary and the Next-step lines update the same way. In the real app this button switches the window for the current session only — the tick under Preferences is the one that decides whether the window is there at the next start.
The 🗑 Clipboard-Clear all button beside Copy to Clipboard and Preview is the app's third clipboard control. It empties TPEE's own clipboard and the Windows clipboard history as well (the list you open with Win+V), so a prompt you copied into a chat window cannot be pasted back out of the history by anyone at the keyboard afterwards. It flashes green and orange while it works and settles on green once the clipboard is verifiably empty. On this page it is the same animation only — a demo, to simulate the real application; nothing in your browser clipboard is touched.
Interactive demo of the app's 📋 Copy to Clipboard and 👁 Preview buttons — a demo only, to simulate the real application: the buttons work exactly like the app, but the prompt behind them is a fixed, complete example (the GreenHouse-One project) with all 13 editor sections filled in. In the real app they copy and preview YOUR sections.
You are a senior embedded firmware engineer with 15 years of experience shipping low-power sensor products on ESP32 hardware. You specialise in C/C++ for the Arduino framework, non-blocking state machines, and explaining design decisions clearly to mixed-skill teams.
1. Review the current firmware in the Data section and identify every blocking call.
2. Refactor loop() into a non-blocking state machine with named states.
3. Add hysteresis and a minimum run time to the fan and pump outputs.
4. Comment every function with one line stating its contract.
5. Flag anything that could fail after 30 days of unattended operation.
We are building GreenHouse-One, a climate controller for a 3 m x 2 m hobby greenhouse. The first prototype worked for a week, then the pump relay stuck ON because loop() blocked for 47 seconds during a Wi-Fi reconnect and the watchdog reset the board mid-cycle. The firmware must run unattended for months. This is version 2 of the firmware and the hardware is already built, so pin assignments cannot change.
Hardware Platform: ESP32-S3-DevKitC-1 (8 MB PSRAM, dual-core 240 MHz). Sensors: SHT31 temperature/humidity on I2C 0x44 (SDA GPIO8, SCL GPIO9), DS18B20 soil temperature on GPIO4, capacitive soil moisture on ADC1_CH3. Actuators: fan relay GPIO12, pump relay GPIO13, both active-LOW. Power: 5 V 2 A supply; the pump draws 800 mA. Toolchain: Arduino IDE 2.3 with the arduino-esp32 core 3.x. Target: 24/7 operation with Wi-Fi telemetry every 60 s.
Answer in Markdown with exactly four headings: ## Diagnosis, ## Refactored Code, ## Wiring Notes, ## Test Checklist. All code in fenced blocks with the language tag. List every behavioural change as a before/after pair under ## Diagnosis.
Two developers maintain this project: an electronics engineer with a strong C background who is new to FreeRTOS, and a final-year student. Both read C fluently; neither has shipped a 24/7 embedded product before.
Direct and methodical. Explain WHY each change matters, not just WHAT changed. No marketing language, no hedging. Cite the datasheet section when you make a hardware claim.
Attached below: main.ino (current firmware, 340 lines), the SHT31 datasheet section 4.5 (measurement timing), the relay module schematic, and a serial log excerpt showing the 47-second watchdog reset during the Wi-Fi reconnect at 03:12:44.
input: The fan relay chatters when the temperature hovers at the setpoint.
output: Add 2 C hysteresis — fan ON at setpoint + 2, OFF at setpoint - 1 — plus a 30-second minimum run time, implemented as explicit states in the state machine under ## Refactored Code.
Include an ASCII wiring table under ## Wiring Notes: SHT31 SDA -> GPIO8, SCL -> GPIO9 with 4.7k pull-ups; DS18B20 data -> GPIO4 with a 4.7k pull-up; soil moisture signal -> GPIO3 (ADC1_CH3); fan relay IN -> GPIO12; pump relay IN -> GPIO13; common ground rail mandatory.
None. This project is developed fully offline and TPEE never connects to any MCP server. All reference material the model needs is attached in the Data section.
If the work is split across agents: Agent 1 reviews sensor timing and I2C error handling, Agent 2 refactors the Wi-Fi reconnect path, Agent 3 writes the hardware test checklist. Merge their findings into one consistent answer before replying.

Location panel
Click to try the toggle
TPEE keeps six paths on screen so you always know where your project lives: the Working Directory, the two Prefix History folders (chats-and-actions and session-start), your Prompts folder, your TPEE Settings folder and your PRDs folder. That is a tall block, so one button folds it away when you need the vertical space back. This is the button and the six rows, exactly as the app draws them.
Interactive replica of the Show/Hide location toggle and the six Path rows — a demo only, to simulate the real application. Press the button: when the panel is shown it reads Hide location of… and the six rows are visible; press it again and it reads Show location of… with the rows collapsed. In the app the same switch is also a tick box on the Preferences menu, and it is remembered between sessions.
Editors
Type, Click or Tap to try features
What is it like to edit a prompt in TPEE? The editor is shown here as an interactive replica of the real application, right here in your browser — one editor at a time. The first is the optional Top of Prompt editor and the last is the optional Bottom of Prompt editor, and the app's numbered prompt sections sit between them.
Top of Prompt Editor
Type, Click or Tap to try features
The Top of Prompt editor — the optional block that sits above the Persona editor. Switch it on and TPEE keeps a five-line Session Number heading at the top of the box; type your own framing below it, watch the live quality indicator re-score on every keystroke, and open the 📋 Quality Guidance dropdown
Top of Prompt✗●
Enter the content that goes at the TOP of your prompt below:
0 characters📋 Quality Guidance
● GREEN: Concise, specific content that sets the stage for the entire prompt.
● YELLOW: Generic or repeated opening text.
💡 TIP: Content here is shown ABOVE the Persona section. TPEE keeps the five-line Session Number heading at the top: "This is Session Number: NNNN", then "The Project Prefix is "PREFIX"". NNNN is the number in your file name and it follows CREATE NEXT PROMPT, NNNN-1 is the session before it, the first Read line names that session's chat and action log, the second names this session's own session-start record, and the fifth line quotes the Working Directory and says the work stays inside it; your own text below the heading is never touched.
●Poor
This interactive replica of the app's Top of Prompt editor works exactly like the real thing — the same live quality indicator (✗ red Poor, ⚠ yellow Needs Work, ✓ green Good) that re-scores on every keystroke with the app's own rule for this block (5 words or more scores Good, 2 or more Needs Work), the same 📋 Quality Guidance text and colours, and a working 📋 Copy Top of Prompt to Clipboard button. It is the box the app draws above the Persona editor, and the text in it is copied to the clipboard as part of the whole prompt — Top first, then the thirteen numbered sections, then Bottom. One honest difference — in the app the five-line heading follows your file name and moves with CREATE NEXT PROMPT, and the box is not saved with a prompt; this browser replica shows the heading of one real session (0742) and keeps your text only while the page is open.
Persona Editor
Type, Click or Tap to try features
The Persona editor, exactly as in the real app — type your own persona, or click the 📋 -- Select or Type -- button to pick from 275 ready-made personas, and open the 📋 Quality Guidance dropdown to see what makes it score GREEN
Persona✗●
Enter your persona below:
0 characters📋 Quality Guidance

● YELLOW: Basic role definition - 'You are a programming assistant' or 'Act as a code reviewer'
💡 TIP: Think about what specific knowledge, experience, or perspective the AI should have for your task.
●Poor
This interactive replica of the app's Persona editor works exactly like the real thing — the same 275-persona library in the 📋 -- Select or Type -- dropdown (type in the filter box to narrow it; when exactly one name matches, the app applies it straight away), the same live quality indicator (✗ red Poor, ⚠ yellow Needs Work, ✓ green Good) that re-scores on every keystroke with the app's own rules, the same 📋 Quality Guidance text and colours, and a working 📋 Copy Persona to Clipboard button. One honest difference — the app saves your persona into your prompt file; this browser replica keeps it only while the page is open.
Instructions Editor
Type, Click or Tap to try features
The Instructions editor, exactly as in the real app — type your own instructions, watch the live quality indicator re-score on every keystroke, and open the 📋 Quality Guidance dropdown to see what makes it score GREEN
Instructions✗●
Enter your instructions below:
0 characters📋 Quality Guidance
● GREEN: Use precise action verbs - 'Analyze the memory management patterns and explain potential memory leaks' vs 'Make the code better'
● YELLOW: Basic actions - 'Review this code' or 'Explain how this works'
💡 TIP: Start with strong verbs: analyze, create, design, implement, optimize, debug, refactor, document. Be specific about what you want done.
●Poor
This interactive replica of the app's Instructions editor works exactly like the real thing — the same live quality indicator (✗ red Poor, ⚠ yellow Needs Work, ✓ green Good) that re-scores on every keystroke with the app's own rules (start with a strong action verb like analyze, create or explain, be specific, and avoid vague words like good or nice), the same 📋 Quality Guidance text and colours, and a working 📋 Copy Instructions to Clipboard button. One honest difference — the app saves your instructions into your prompt file; this browser replica keeps them only while the page is open.
Context Editor
Type, Click or Tap to try features
The Context editor, exactly as in the real app — type your own context, watch the live quality indicator re-score on every keystroke, and open the 📋 Quality Guidance dropdown to see what makes it score GREEN
Context✗●
Enter your context below:
0 characters📋 Quality Guidance
● GREEN: Relevant background info - 'This is a real-time embedded system with 64KB RAM constraints, using Rust no_std' vs generic context
● YELLOW: Basic context - 'This is for a web application' or 'Working on a school project'
💡 TIP: Include technical constraints, target environment, performance requirements, or specific domain knowledge needed. Keep it focused and relevant.
●Poor
This interactive replica of the app's Context editor works exactly like the real thing — the same live quality indicator (✗ red Poor, ⚠ yellow Needs Work, ✓ green Good) that re-scores on every keystroke with the app's own rules (good context is informative but concise: the app scores word count against text density), the same 📋 Quality Guidance text and colours, and a working 📋 Copy Context to Clipboard button. One honest difference — the app saves your context into your prompt file; this browser replica keeps it only while the page is open.
Technical Specs Editor
Type, Click or Tap to try features
The Technical Specs editor, exactly as in the real app — type your own technical specifications, or click the 📟 -- Select Hardware -- button to pick from 230 development boards and auto-fill the specs, watch the live quality indicator re-score on every keystroke, and open the 📋 Quality Guidance dropdown to see what makes it score GREEN
Technical Specs✗●
Enter your technical specifications below:
🔧 Hardware / Development Board Selection230 boards available
● YELLOW: Basic specs - 'Microcontroller with 1MB memory, fast SPI' or 'Embedded system requirements'
💡 TIP: Include specific hardware (processor, memory, interfaces), performance constraints (timing, power), standards compliance (MISRA, ISO), and environmental requirements (temperature, EMI). Use exact numbers and units.
●Poor
This interactive replica of the app's Technical Specs editor works exactly like the real thing — the same 🔧 Hardware / Development Board Selection with 230 boards (type in the Filter box to narrow the list; when exactly one board matches, the app selects it straight away), the same board photos (the app's own bundled photos, resized for the web — click a photo to enlarge it), the same auto-fill that writes the selected board's platform, MCU, features and best-for into the editor, the same live quality indicator (✗ red Poor, ⚠ yellow Needs Work, ✓ green Good) that re-scores on every keystroke with the app's own rules (specific hardware, constraints, exact numbers and units), the same 📋 Quality Guidance text and colours, and a working 📋 Copy Technical Specs to Clipboard button. Two honest differences — the app saves your specs into your prompt file while this replica keeps them only while the page is open, and the app's 📂 Open Image Folder button (it opens Windows Explorer) does not exist on the web.
Format Editor
Type, Click or Tap to try features
The Format editor, exactly as in the real app — specify exactly how you want the output formatted, watch the live Quality: indicator re-score on every keystroke, and open the 📋 Quality Guidance dropdown to see what makes it score GREEN
FormatQuality:Poor
Enter your format below:
0 characters📋 Quality Guidance
● GREEN: Precise format specs - 'Return as JSON with fields: {"issue": string, "severity": 1-5, "fix": string}' or 'Markdown with ## headers, code blocks, and bullet points'
● YELLOW: Basic format - 'JSON format' or 'As a numbered list'
💡 TIP: Specify exact structure, field names, data types, headers, or markup. Think about how you want to consume the output.
●Poor
This interactive replica of the app's Format editor works exactly like the real thing — the same fixed-height monospace editor, the same live Quality: indicator (Poor / Needs Work / Good) that re-scores on every keystroke with the app's own rules (name a structure like JSON, a table or a bullet list, plus specifics like headers, sections or markdown), the same 📋 Quality Guidance text and colours, and a working 📋 Copy Format to Clipboard button. One honest difference — the app saves your format into your prompt file; this browser replica keeps it only while the page is open.

💡 TIP: Think about formality level, technical depth, teaching style, and emotional approach. Match the tone to your audience and purpose.
●Poor
This interactive replica of the app's Tone editor works exactly like the real thing — the same fixed-height monospace editor, the same live Quality: indicator (Poor / Needs Work / Good) that re-scores on every keystroke with the app's own rules, the same 📋 Quality Guidance text and colours (a specific communication style scores best), and a working 📋 Copy Tone to Clipboard button. One honest difference — the app saves your tone into your prompt file; this browser replica keeps it only while the page is open.

The Example(s) editor, exactly as in the real app — show concrete input/output examples, watch the live quality indicator re-score on every keystroke, and open the 📋 Quality Guidance dropdown to see what makes it score GREEN
💡 TIP: Show concrete before/after examples. Demonstrate the exact input format and desired output structure. Multiple examples show edge cases.
●Poor
This interactive replica of the app's Example(s) editor works exactly like the real thing — the same live quality indicator (✗ red Poor, ⚠ yellow Needs Work, ✓ green Good) that re-scores on every keystroke with the app's own rules (it looks for concrete input/output pairs or phrases like for instance and such as, and rewards several examples), the same 📋 Quality Guidance text and colours, and a working 📋 Copy Example(s) to Clipboard button. One honest difference — the app saves your examples into your prompt file; this browser replica keeps them only while the page is open.

💡 TIP: Specify diagram type, content details, annotations, colors, layout, and purpose. Think about what visual elements will clarify your technical content.
●Poor
This interactive replica of the app's Graphics editor works exactly like the real thing — the same live quality indicator (✗ red Poor, ⚠ yellow Needs Work, ✓ green Good) that re-scores on every keystroke with the app's own rules, and the same 📋 Quality Guidance text and colours (a specific diagram type with content, annotations and purpose scores best). Two honest notes — the Graphics section has no copy button in the app (mirrored here exactly), and the app saves your graphics details into your prompt file while this browser replica keeps them only while the page is open.
MCP Servers Editor
Type, Click or Tap to try features
The MCP Servers editor, exactly as in the real app — note the MCP server configurations your prompt should cite, watch the live quality indicator re-score on every keystroke, and open the 📋 Quality Guidance dropdown to see what makes it score GREEN
MCP Servers✗●

This interactive replica of the app's MCP Servers editor works exactly like the real thing — the same live quality indicator (✗ red Poor, ⚠ yellow Needs Work, ✓ green Good) that re-scores on every keystroke with the app's own rules, the same 📋 Quality Guidance text and colours, and a working 📋 Copy MCP Servers to Clipboard button. Two honest notes — this section is configuration text for your prompt: TPEE itself never connects to any MCP server (it is 100% offline by design), and the app saves your text into your prompt file while this browser replica keeps it only while the page is open.
Verification of Results & Outcome Editor
Type, Click or Tap to try features
The Verification of Results & Outcome editor, exactly as in the real app — say how you will check the result and what good and excellent look like, watch the live quality indicator re-score on every keystroke, and open the 📋 Quality Guidance dropdown to see what makes it score GREEN
Verification of Results & Outcome✗●
What will you check, and what does good or excellent look like?
0 characters📋 Quality Guidance
● GREEN: You name what GOOD and EXCELLENT look like AND the check you will run - 'I will verify your work by running the module on Ubuntu 24.04 and comparing the three sample outputs with section 4; good is all three matching, excellent is all three matching with the reasons for each difference written down.'
● YELLOW: A check is named but no standard - 'I will run it and see if it looks right.'
💡 TIP: Start with 'I will verify your work by ...' and then add three things: WHAT you will check (a test to run, a file or page to open, a number to read, a person to ask), WHEN you will check it (after every step, at the end, before you send it on), and what GOOD and EXCELLENT look like - so the model knows what it is aiming at. A check you cannot describe is a standard the model cannot meet. Examples: 'I will verify your work by running cargo test and reading the pass count' / 'I will verify your work by comparing every price with the supplier PDF' / 'I will verify your work by asking three real users to sign up once, unaided.'
●Poor
This interactive replica of the app's Verification of Results & Outcome editor works exactly like the real thing — the same live quality indicator (✗ red Poor, ⚠ yellow Needs Work, ✓ green Good) that re-scores on every keystroke with the app's own rules, the same 📋 Quality Guidance text and colours (naming what GOOD and EXCELLENT look like and the check you will run scores best), and a working 📋 Copy Verification to Clipboard button. One honest difference — the app saves this section into your prompt file; this browser replica keeps it only while the page is open.

● GREEN: Specific agent definitions with roles, capabilities, and workflows
● YELLOW: Basic agent names or simple configurations
💡 TIP: Define AI agents with specific roles, capabilities, and interaction patterns for complex task automation.
●Poor
This interactive replica of the app's Agents editor works exactly like the real thing — the same live quality indicator (✗ red Poor, ⚠ yellow Needs Work, ✓ green Good) that re-scores on every keystroke with the app's own rules, the same 📋 Quality Guidance text and colours (specific agent definitions with roles, capabilities and workflows score best), and a working 📋 Copy Agents to Clipboard button. One honest difference — the app saves your agents configuration into your prompt file; this browser replica keeps it only while the page is open.
Bottom of Prompt Editor
Type, Click or Tap to try features
The Bottom of Prompt editor — the optional block that sits below the Agents editor. Switch it on and TPEE keeps a two-line closing instruction at the bottom of the box; type your own sign-off above it, watch the live quality indicator re-score on every keystroke, and open the 📋 Quality Guidance dropdown
Bottom of Prompt✗●
Enter the content that goes at the BOTTOM of your prompt below:
0 characters📋 Quality Guidance
● GREEN: Concise, specific closing content that wraps up the prompt.
● YELLOW: Generic or repeated closing text.
💡 TIP: Content here is shown BELOW the Agents section. TPEE keeps the two-line closing instruction at the bottom of this box: the first line asks the model to write up this session's chats and actions (the ones you typed) and names the file to save them in, the second asks for the record the NEXT session needs and names its file. The two numbers follow your file name and move with CREATE NEXT PROMPT; your own text above them is never touched.
●Poor
This interactive replica of the app's Bottom of Prompt editor works exactly like the real thing — the same live quality indicator (✗ red Poor, ⚠ yellow Needs Work, ✓ green Good) that re-scores on every keystroke with the app's own rule for this block (5 words or more scores Good, 2 or more Needs Work), the same 📋 Quality Guidance text and colours, and a working 📋 Copy Bottom of Prompt to Clipboard button. It is the box the app draws below the Agents editor, and the text in it is copied to the clipboard as part of the whole prompt — Top first, then the thirteen numbered sections, then Bottom. One honest difference — in the app the two closing lines follow your file name and move with CREATE NEXT PROMPT, and the box is not saved with a prompt; this browser replica shows the closing lines of one real session (0742) and keeps your text only while the page is open.

This interactive replica of the User's Manual shows the complete manual exactly as it ships with the app — the same three documents, the same table of contents. Download the app to always carry the latest edition with you.
Learning Center
Type, Click or Tap to try features
The Learning menu's Open Learning Center button, click it to see a sample
This interactive replica of the Learning Center - TPEE Professional AI Course shows the complete course exactly as it ships with the app — the same 94 lessons and the same 282 quiz questions, the same window layout. Take a real quiz: it is graded exactly like in the app. One honest difference — the app saves student progress to disk; this browser replica keeps it only while the page is open. Or read three of the most-asked questions for free on the web: what prompt engineering is, what MCP servers are, and what an AI agent is. The whole course is online too: all 94 lessons, free to read.
ClassRoom Presentation
Type, Click or Tap to try features
The Learning menu's ClassRoom Presentation button, click it to see a sample
This replica shows the two presenting modes of the window the app ships: all three TV-MIRE projector cards with the PLUGE and safe-zone bars, and the lesson slides carrying the same 94 lessons and 282 quiz questions as the Learning Center. Present a lesson, click a bullet to highlight it, switch on 🗒 Lecturer Notes, or turn on ⌨ Keys (off by default) and drive the slides with the arrow keys, Space, Page Up / Page Down and Home / End. The window's third mode, 🗓 Course Organizer, is the lecturer's planner and is described beside this card: the course name and location, its start and end date and time, an editable day of lesson blocks and breaks, a Done tick with the recorded time for every bullet point and every lesson, an estimate of the hours and days the course will take — and a course calendar that asks which weekdays the course lectures on, which dates are days off, and how much allowance to leave for a course that keeps growing, then draws a 42-cell month grid and answers the planning question in one line: whether the days you have reserved are enough. Four honest differences: this replica draws the two presenting modes, not the Course Organizer; it saves nothing — the lesson-list width and the notes divider reset when you close it, while the app keeps both until you close TPEE; Maximize fills this browser tab, not a projector screen; and it draws one dark slide, while the app's highlight band follows your theme. F1 help is Windows-only.
PRD Innovator
Type, Click or Tap to try features
The PRD Innovator menu, click it to see everything it can do
This replica shows the whole PRD Innovator: the menu with New, Open and Save PRD and the four Quick Start rows; the Economic Sectors Day to Day Work family of one hundred and thirty-nine offices in thirty-seven sectors of activity, each sector switchable on or off; the seventeen smart blocks every office PRD carries; the PRD Editor window with its twelve sections and its Generate Prompt button; and the one-box search that finds any office by name, its summary or its sector. Click the rail on the left to walk through each part. One honest difference: this replica is read-only — it opens no file and writes nothing — and the app itself is fully offline.
Prompt OnBoarding checklist
On before you read the manual
The editor toolbar's OnBoarding toggle and the floating window it opens
TPEE opens with a 26-step checklist in a floating window, before you have read a word of the manual: the toolbar button reads Using OnBoarding until you switch it off. The steps are grouped in the order you actually work — Before you start (read the User's Manual, complete the lessons), the working environment (the Working Directory, the four Prefix, Prompts and TPEE Settings paths, File Name and Project Prefix), the prompt (the optional Top of Prompt editor, the thirteen sections, the optional Bottom of Prompt editor), the Prompt Enhancing Workflow, and the finishing moves (Preview, Clipboard-Clear all, Copy to Clipboard, paste into your chat window). Where TPEE can see a step for itself it says so beside the row — a folder is set or it is not, a section has text or it has not — and one button ticks every step TPEE can already see. Rows that are your own judgement carry no badge, because nothing in the program can see them and claiming otherwise would be a lie. Nothing you tick is written to disk: the ticks last for the run, and the only setting this feature remembers is the Preferences tick that decides whether the window is there next time you start TPEE. F1 help is Windows-only.
IDE Selection

Model:
This interactive replica of the app's Model combobox shows the 182 AI models across 23 providers exactly as they ship with the app — the same list, the same type-to-filter box, the same provider groups, the same selection behaviour, the same status line. In the real app the chosen model also drives prompt formatting, scoring, the optimization tips and the PRD generator — and on first run the app pre-selects its default, Claude Fable 5. The model list is updated weekly in the real app — download the app to always carry the latest model profiles with you.
API Character Limits

The Show API Limits button, click it to see a sample
This interactive replica of the app's API Character Limits panel shows the 182 AI models across 23 providers exactly as they ship with the app — the same provider columns, the same cards, the same pricing, the same newest-first order. Two honest differences: in the real app the coloured bar on each card fills with your live prompt's character count and shifts green → yellow → orange → red as you approach the model's limit (here it sits at 0%), and the gold frame follows your selected model (the app pre-selects Claude Fable 5 on first run). The limits and pricing are updated weekly in the real app — download the app to always carry the latest numbers with you.
Model / Commands (reference)
Type, Click or Tap to try features
The Show Kimi / Commands button, click it to see a sample
This interactive replica of the app's per-model command reference panel shows the same offline command sheets exactly as they ship with the app — the same 16 model-family sheets, the same tutorial, the same "Selected:" banner. The replica starts on Kimi K3, so the button reads "Show Kimi / Commands" and opens the "Kimi / Commands (reference)" window; pick any model in the Model combobox above and the button and the window follow automatically — Models / Commands change with the selected model, exactly like the real app (a GLM model now opens its own GLM sheet, and a Hermes model opens the Hermes sheet ). The command sheets are updated weekly in the real app — download the app to always carry the latest commands with you.
Optimization Tips
Type, Click or Tap to try features
The Show Tips button, click it to see a sample
This interactive replica of the app's Optimization Tips panel shows the same context-aware tips exactly as they ship with the app — the same tip engine, the same four categories (📐 Structure, 🎨 Style, 📏 Length, ⚡ Features), the same colours. The tips are computed for the IDE and the model selected in the IDE and Model comboboxes above and change automatically with your selection, exactly like in the real app — try it: open the tips, then pick another IDE or model above and watch the window follow (on first run the app itself pre-selects Cursor + Claude Fable 5). The optimization tips are updated weekly in the real app — download the app to always carry the latest tips with you.
Projects Prefixes
Type, Click or Tap to try features
The 📋 Projects Prefixes button, click it to view the Projects Prefixes Library window
File Name:Project Prefix for Filename:_Pmt_NNNN.txt
This interactive replica shows the app's File Name / Project Prefix toolbar row and the 📋 Projects Prefixes Library window exactly as they ship with the app — the same fields, the same defaults (File Name "prompt.txt", Project Prefix "T1042CW"), the same Add / quick-add / select / remove behaviour, the same status messages. Everything works: type a prefix, add it to the library, click a saved prefix to load it into the Project Prefix field, remove one with the 🗑 button — saved prefixes name your files PREFIX_Pmt_NNNN.txt (e.g., T1042CW_Pmt_0001.txt). One honest difference — the app saves your library to its preferences file so it survives restarts; this browser replica keeps it only while the page is open.

PRD Innovator — TPEE
One-click starts
The PRD Innovator turns a rough idea into a structured Product Requirements Document. Open the menu and pick how you want to begin.
📋 New PRD...
📂 Open PRD...
💾 Save PRD
Quick Start:
🖥️ Multi-Platform PRD
💻 Individual App PRD
📱 Mobile Device PRD
🌐 Multi-Faced Platform PRD
New PRD asks what kind of platform you are building and opens a document already shaped for it. Open and Save PRD read and write your own PRD files. The four Quick Start rows skip the form and begin straight away, each naming the PRD after the platform type.
Economic Sectors Day to Day Work
The Quick Start rows ask what kind of software you are building. The Economic Sectors Day to Day Work rows ask what kind of office is doing the work. Each one opens a PRD already filled in with that office's daily requirements — the recurring tasks, the workflow, the deadlines, the records and the compliance rules.
139 of 139 offices are switched on across 37 sectors of activity.
🩺 Medical and Dental Practice - Day to Day Work
⚖️ Lawyers Office - Day to Day Work
🧮 Accountant Office - Day to Day Work
🏠 Real Estate Agency - Day to Day Work
🚚 Freight and Logistics Office - Day to Day Work
… and 134 more, from a veterinary practice to a furniture and joinery maker
The offices are filed under thirty-seven sectors of activity. Switch a sector on or off with the tick beside it and its whole shelf appears or disappears; two buttons turn every sector on, or every sector off, in one click. The whole tree sits in its own scroll area, so it stays usable as the family keeps growing.
Every office PRD carries 17 smart blocks
Each Day to Day Work PRD ends its Requests the Assistant Will Receive section with seventeen blocks that turn a description into a brief an office can actually hand to an assistant:
How to brief the assistant for this office
How this office measures the day — the one number the office lives by
When to stop and hand back to a person
How to tell the assistant's answer was good enough
A worked example for this office
What the assistant must never do in this office
What the assistant must ask for before it starts
What the assistant must hand over at the end of the day
Who the assistant works alongside and what each of them needs
What the assistant must do when the day starts wrong
How this office's week differs from its day
What must happen at month end in this office
How this office's year differs from its months
What the assistant must do in its first 90 days in this office
How this office reviews the assistant and when it retires it
What this office expects the assistant to do with a correction, and how it knows the lesson has landed
Where this office will be in three to five years, and what the assistant must do now to serve it new in the latest build
Every block is written in that office's own terms — a pharmacy, a quarry, a law firm and a bakery each get their own words — so the template is a real brief rather than a description.
The PRD Editor
Any PRD opens in the PRD Editor window, a real, movable, resizable window with Maximize, Minimize and Restore. Its twelve sections are:
Persona
Instructions
Context
Technical Specifications
Format
Audience
Tone
Data
Example(s)
Graphics
MCP Servers
Agents
Each section carries a quality indicator and a character count, and the window closes with a Requests the Assistant Will Receive section. A Generate Prompt button turns the whole document into a ready-to-paste prompt, and Save, Save As and Open write and read your PRD files in the folder you chose under the Location panel.
Find any office
With one hundred and thirty-nine offices, browsing the tree is fine when you know the sector and hopeless when you do not. One box searches every office in every sector at once.
Type a word - an office, or a sector, for example pharmacy, depot, tribunal, studio or forestry
3 office(s) match 'pharmacy' - by office name, summary or sector name - click one to open its PRD
💊 Retail Pharmacy - Day to Day Work [Health and Care] - office 3 of 6 in its sector
🧪 Compounding Pharmacy - Day to Day Work [Health and Care] - office 6 of 6 in its sector
🏭 Pharmaceutical Manufacturing Plant - Day to Day Work [Pharmaceuticals and Medical Supplies] - office 1 of 3 in its sector
A hit says why it matched — the office name, its summary or its sector — and where it sits inside its own sector. Above the box, a Today's office to try row opens a different office every day, in date order, so the whole family gets seen.
By the numbers
139 offices in 37 sectors of activity, each with a one-click start
17 smart blocks in every office PRD

Features
Everything in TPEE exists to answer one question: is this prompt ready? The score tells you. The sections show you why.
Prompt Enhancing Workflow
The Use Prompt Enhancing Workflow button turns prompt writing into a guided conversation: TPEE wraps your prompt between a Pre-Prompt and a Post-Prompt, you paste the bundle into any LLM chat, and the model helps you improve the prompt before you ever use it. How it works ↓
Prominent feature
Editor & Scoring
Persona, Instructions, Context, Technical Specs, Format, Audience, Tone, Data, Examples, Graphics, MCP Servers, Verification of Results & Outcome, Agents — thirteen sections, each with a GREEN/YELLOW/RED readiness indicator, rolled into a 0–100 quality score.
Models & Limits
182 model profiles across 23 providers, with pricing, context windows, and API character limits — so the prompt you write fits the model you'll actually run.
IDE Export
Format once, export anywhere: 50 IDE profiles including Cursor, VS Code variants, Claude Code, Kiro, and Devin Desktop.
Library, Versions & Backup
A local prompt library with version history and automatic backups keeps every draft safe on your machine.
PRD Innovator
PRD Innovator turns rough ideas into structured requirements.
Claude Team Designer and the Team Management suite organize multi-agent work.
Learning Center
94 lessons and 282 quiz questions, built in. TPEE doesn't just hold your prompts — it teaches the craft.
Hardware Catalogue
A catalogue of development boards with photos, for prompt engineers who also push bits.
Accessibility Themes
High-contrast, color-blind-support, and low-vision themes make the editor usable by everyone on the team.
Run from USB Stick
TPEE runs from your USB stick, so you can learn anywhere you go: insert the USB stick into any Windows-compatible computer, double-click the TPEE.exe file on it (no installation required) and continue learning on the go. Your learning progress is kept on the USB stick — nothing is installed on the computer you plugged it into.
Prominent feature
The Prompt Enhancing Workflow
Don't just write a prompt. Have a conversation with the LLM about it first. One button in the top panel guides you through five steps using local files and your clipboard. TPEE never contacts an LLM; you drive the conversation.
Switch it on. Tick the workflow box next to the
Use Prompt Enhancing Workflow button — everything else
in the editor stays exactly as you know it.
Edit the Pre-Prompt. It tells the LLM that a prompt
to improve follows, and to act as an expert prompt engineer. It's saved
next to your prompt as a *_Pre_Pmpt.txt
companion file.
Edit the Post-Prompt. It tells the LLM how to
discuss your prompt and where to save the result, as a
*_Post_Pmpt.txt file. The suggested save path
always matches your real prompt folder and file name.
Combine and converse. One click copies
Pre-Prompt + your prompt + Post-Prompt to the clipboard. Paste it into
any LLM chat and improve the prompt together — the model asks
questions, you answer, the prompt gets sharper.
Use the enhanced prompt. Open the
*_Enhanced.txt file the LLM saved, verify or
tweak it in the editor, then copy it to the clipboard for a fresh chat
session — the session where the prompt does its real work.
100% local: marker lines frame your prompt like
delimiters in a serial protocol, companion files live next to your
prompt, and the only transport is your clipboard. No network, no
account, no middleman.
The PRD Innovator's second family of one-click starts asks
what kind of office is doing the work, not what kind of software you
are building. thirty-seven sectors of activity, one hundred and thirty-nine offices,
and every office opens a PRD that is already filled in with its daily requirements -
then names the number it lives by, when to stop and hand back
to a person, what the assistant must never do, what
must happen at month end, where the office will be in three to five
years and what the assistant must do first thing each morning
- nineteen smart blocks per office. The whole family, every sector and every office card,
is on its own page so this page stays quick to read.

The productivity tool for all AI work
TPEE is the productivity tool of choice for all AI work, and especially for people who keep at it. Here is why, in plain terms.
Thirteen numbered prompt sections, scored 0–100. Every prompt is measured across the app's thirteen numbered sections and scored 0–100, with per-section feedback on the one you have just written — so you can see which part is weak before you paste it anywhere.
It works without connecting to an AI. No API key, no account, no sign-in — you write the prompt, TPEE scores it, and you paste it wherever you like.
It works offline. Nothing you type leaves the machine. The only two outbound paths are the release check and the feedback form you choose to use, and both are yours to switch off.
It works with all LLMs. The editor is model-agnostic: the same prompt is measured and priced against 182 models from 23 providers, so retargeting it to a different one costs you nothing.
It works with all IDEs, all CLI agents and all agent harnesses. The prompt is exported formatted for the tool in front of you — 50 IDE profiles, 63 CLI profiles and 48 harness profiles.
It is updated every week. The model catalogue — the models, their context windows and both prices — is re-checked weekly, so the numbers you plan around are the current ones. The app itself ships on the release schedule published on the download page.
Its releases are code-signed, after testing. Every release is built, tested and signed before it is published. The signature is what tells you the file is ours and has not been altered on the way to you.
Every correction comes from feedback. Fixes are raised from what users report, written down as a defect with a measurement, and closed by a test — not by guesswork.
One-time purchase, 14-day refund, Toptronic® Lifetime Warranty. Windows 10 and 11. Built for people who use AI every day, and for the long term.
Releases arrive on a schedule
Code-signed releases are published every two weeks. Information about builds we have not yet signed is published for reference, because it is useful to see what is coming.
What you are entitled to under the maintenance plan is the code-signed release, and it arrives on that schedule — not every day.
Code-signed is what you download. Nothing unsigned is ever offered for sale or for download.
Pricing
One-time purchase. Updates are included with every plan — no subscriptions.
Prices are in US dollars, and Stripe charges the USD amount. The figure under each plan is an approximate local-currency equivalent for — your own bank converts it, at its rate.
What happens after you pay: every plan is a one-time purchase — USD $49, $99 or $299 — the app keeps working forever, and every plan carries a 14-day refund, no questions asked.

Not sure which one is you? Find your line:
Studying or retraining — Student, USD $49, 4 months of updates — checkout like any other plan, no approval step.
One person using it themselves — Starter, USD $99, 1 user, 6 months of updates.
Using it commercially — Professional, USD $299, 1 commercial user, 12 months of updates, priority release access.
Buying it for someone else — The Gift of the Future, USD $299, the Professional plan delivered by email to the recipient.
The plans do not differ in the app. Every plan is the full app — what changes is how long updates continue after you buy (4, 6 or 12 months of updates) and how many people may use one licence (1 user on Starter, 1 commercial user on Professional). When the update window ends the app keeps working; you simply stop receiving new builds.
No free plan — every plan helps cover the infrastructure it runs on.
Accepted beta testers get 30% off the Professional plan with code BETA30 — see the beta program.
Put the price in context: ChatGPT Plus and Claude Pro are $20 a month — $240 a year, forever. TPEE is a one-time $99 (Starter) and keeps working after the 6 months of updates. A single afternoon of wasted API calls costs more than the licence.
One-time purchase. Up to 12 months of updates included by plan — the app keeps working forever after. Payments processed by Stripe.
Refunds: within 14 days of purchase, no questions asked. The refund is paid through Stripe minus what the refund costs us: a flat fee of 15% of the amount plus USD 5, together with administrative, accounting, financial, exchange-rate, legal and other processing fees charged to us by your purchase and your refund instruction. The full wording is on the terms of purchase page. Just email us from your order address.

FAQ
Straight answers, no fine print.
Does TPEE really work offline?
Yes — the app works offline, and sends nothing you did not ask to send. The only two paths out are Help > Check for Updates (which also runs once at start-up until you untick 'Check for Updates at Start up') and Help > Send Feedback. No telemetry, no account needed to write prompts. Verify with your firewall; we encourage it. (The website and Stripe checkout are online, obviously.)
Windows SmartScreen warned me when I ran the installer. Is it safe?
Yes - it is safe, and you can check it yourself in a minute. Every release we sell is code-signed with an EV certificate in the name of Toptronic Ltd. SmartScreen can still show a warning the first time it sees a brand-new signed installer, because a file earns its reputation with Windows over time, not the moment it is signed - so the warning says nothing about the file. To continue, click More info, then Run anyway. Before you run it, confirm the download is ours: the published file name and its SHA-256 should match, and the certificate should name Toptronic Ltd. If the name, the publisher or the hash does not match, stop and email us instead. Step-by-step verification is on our Security page.
Is there a free plan?
No — running the infrastructure costs money, so every plan is paid. The Student plan is USD 49.00 and includes 4 months of updates: choose the plan on the pricing section and pay by card — no approval step.
What does the quality score actually measure?
Each of the 13 prompt sections is checked for completeness and internal consistency, shown as GREEN/YELLOW/RED, and rolled into a 0–100 score. It won't write the prompt for you — it tells you when you've done the work.
Which IDEs can I export to?
50 profiles, including Cursor, VS Code and its variants, Claude Code, Kiro, and Devin Desktop — plus a general formatter if your tool isn't listed.
Which AI models does it cover?
182 model profiles across 23 providers, with pricing, context windows, and API character limits. TPEE doesn't call these models for you — it helps you write prompts that fit them.
MSI installer
Both. Same app, same build: MSI for a normal Windows install, ZIP for run-from-anywhere (no admin rights needed).
Windows only? What about Mac or Linux?
Windows 10 and 11 only, for now. It's a native Rust/egui app, and we'd rather support one platform properly than three poorly.
What's the beta program?
Accepted beta testers get 30% off the Professional plan (code BETA30) in exchange for short monthly feedback. Details and application: beta program.
Is it really worth the price?
Compare it to a ChatGPT Plus or Claude Pro subscription — see the numbers on the pricing page.

TPEE sends nothing you did not ask to send.
