What is RepoPrompt for Windows?

RepoPrompt is a context engineering tool for AI coding agents. It solves a simple but critical problem:

When you paste a codebase into ChatGPT, Claude, Gemini, or any LLM — you are paying by the token. Every irrelevant file is wasted context and wasted money. RepoPrompt lets you surgically select which files to include, slice them to specific line ranges, track your token budget, and generate clean, LLM-optimized XML output.

Think of it as a curated context window builder for your codebase.

Why RepoPrompt?

	RepoPrompt	Raw copy/paste
File tree + structure	✅ Automatic file map included	❌ Manual
Token counting	✅ Per-file and total with budget warnings	❌ Blind guessing
Line-range slicing	✅ Include only relevant sections	❌ Whole file or nothing
.gitignore-aware	✅ Respects existing ignore rules	❌ Risk of leaking secrets/configs
Git diff support	✅ Include staged/unstaged changes	❌ Manual git diff
Output format	✅ XML/Markdown/Text — optimized for LLMs	❌ Raw, unstructured
MCP server	✅ External agents can query your workspace	❌ Not possible
Copy to clipboard	✅ One-click	❌ Manual select + copy

✨ Features

• 📁 Multi-root workspace — Open one or more folders. Browse the full file tree.
• 🔍 File browser with search — Filter files by name, extension, or path. Checkboxes for selection.
• 💰 Token budget management — See token counts per file and total. Set a budget slider — get warned when you exceed it.
• ✂️ Line-range slicing — Don't need the whole file? Select specific line ranges to include only what matters.
• 🚫 Smart ignore — Respects .gitignore, .repoprompt-ignore, and custom ignore patterns. Automatically skips binaries, images, and common noise.
• 📋 LLM-optimized output — Generates clean XML (Repomix-style <context> format), Markdown, or plain text. One-click copy to clipboard or save as .txt/.md/.xml.
• 🔄 Git integration — Detects git repos, shows branch info, and can include staged/unstaged diffs in your context.
• 🔌 Basic MCP server — Expose your workspace context to external AI agents via a JSON-RPC TCP server.
• ⚙️ Customizable — Default ignore patterns, hidden file visibility, max file size, output format preferences.

💡 Workflow

1. Open a project folder
   ↓
2. Browse the file tree — search, filter, select
   ↓
3. (Optional) Set line ranges on specific files
   ↓
4. Set your token budget (slider)
   ↓
5. Hit "Build Context"
   ↓
6. Copy to clipboard or save as .xml/.md/.txt
   ↓
7. Paste into ChatGPT, Claude, Gemini, Cursor, or any AI tool

That's it. No accounts. No cloud. No telemetry. Just a curated context window for your AI pair programmer.

---

Who is this for?

• Developers using AI coding agents — ChatGPT, Claude, Gemini, Cursor, Copilot, Codex CLI, etc.
• Anyone who pastes code into LLMs and wants to control token usage
• Teams sharing code context — generate standardized context files for reproducible AI interactions
• Agent orchestration — when you want an external agent (via MCP) to understand your full project structure

Security & Privacy

RepoPrompt is a local-first context tool. Period.

• ✅ No cloud — All files are read from and written to your local filesystem.
• ✅ No telemetry — Zero data collection. No analytics. No pings.
• ✅ No accounts — No sign-up, no login, no cloud sync.
• ✅ No network requests — The app never makes an external network call.
• ✅ Local storage — Settings live entirely in %APPDATA%\com.miaailab.reprompt\.
• ✅ Safe file handling — Binary files are detected and skipped. .gitignore is respected by default.

🙏 Acknowledgments

This project is a Windows port and evolution of RepoPrompt CE by @r3m00n. The original macOS app pioneered the context engineering workflow, and this port brings that same philosophy to Windows with a full stack rewrite in Tauri 2 + Rust + React.

Huge thanks to the original author for the inspiration and the excellent design patterns.
