Interactive replica of the “USE PROMPT ENHANCING WORKFLOW” (Build 294). Tick the square, then walk the steps with the arrows or the numbered circles — the colours change exactly as in the app. The download does the real workflow. Read how it works ↓

Interactive demo of the app's 📋 Copy to Clipboard and 👁 Preview buttons (Build 294) — 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 12 editor sections filled in. In the real app they copy and preview YOUR sections.

Editors

What is it like to edit a prompt in TPEE? Each of the 12 section editors is shown as an interactive replica of the real application, right here in your browser — one editor at a time.

Persona Editor

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

● GREEN: Be specific about expertise - 'You are an expert Rust programmer with 10 years experience in systems programming and embedded development' vs vague 'You are helpful'

● 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 (Build 294) — 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

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'

💡 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 (Build 294) — 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

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

● 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 (Build 294) — 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

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

Poor

This interactive replica of the app's Technical Specs editor works exactly like the real thing (Build 294) — 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

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

One honest difference — the app saves your data into your prompt file; this browser replica keeps it only while the page is open.

Example(s) Editor

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

● YELLOW: Basic examples - 'For example: check memory allocation' or 'Like analyzing malloc() calls'

💡 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 (Build 294) — 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.

Functions

What do TPEE's functions actually do? Each one is shown as an interactive replica of the real application, right here in your browser — one function at a time.

User's Manual

The User's Manual button, click it to see a sample

This interactive replica of the User's Manual shows the complete manual exactly as it ships with the app (Build 294) — the same three documents, the same table of contents. Download the app to always carry the latest edition with you.

Learning Center

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 (Build 294) — the same 83 lessons and the same 249 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 83 lessons, free to read.

IDE Selection

The IDE combobox, click it to see a sample

IDE:

This interactive replica of the app's IDE combobox shows the 34 IDE profiles exactly as they ship with the app (Build 294) — the same list, the same selection behaviour, the same status line. In the real app the chosen IDE also drives prompt formatting, export, scoring and the optimization tips. The IDE list is updated weekly in the real app — download the app to always carry the latest IDE profiles with you.

Model Selection

The Model combobox, click it to see a sample

Model:

This interactive replica of the app's Model combobox shows the 191 AI models across 20 providers exactly as they ship with the app (Build 294) — 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 191 AI models across 20 providers exactly as they ship with the app (Build 294) — 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)

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 (Build 294) — 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 (Build 294)). The command sheets are updated weekly in the real app — download the app to always carry the latest commands with you.

Optimization Tips

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 (Build 294) — 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

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 (Build 294) — 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.

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, Agents — twelve sections, each with a GREEN/YELLOW/RED readiness indicator, rolled into a 0–100 quality score.

Models & Limits

191 model profiles across 20 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: 34 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 & Teams

Claude Team Designer and the Team Management suite organize multi-agent work.

Learning Center

83 lessons and 249 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.

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
Pre-Prompt  +  Your Prompt  +  Post-Prompt   →   clipboard   →   LLM chat   →   TPEE_Pmt_0001_Enhanced.txt

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.

FAQ

Straight answers, no fine print.

Does TPEE really work offline?

Yes — the app makes no network calls at runtime. 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?

That warning appears for apps without an expensive EV code-signing certificate — not because something is wrong. Click “More info → Run anyway”. Before you do, verify your download against the SHA-256 hash we publish on our Security page.

Is there a free plan?

No — running the infrastructure costs money, so every plan is paid. The Student and Job Seeker plans are USD 20.00 each, pending approval: apply from the pricing section and we review every application ourselves, then reply by email.

What does the quality score actually measure?

Each of the 12 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?

34 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?

191 model profiles across 20 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.
