CLAUDE.md Generator
Generate the perfect CLAUDE.md for your project. Step-by-step wizard with framework-specific templates and live preview.
What is CLAUDE.md?
CLAUDE.md is a special markdown file placed at the root of your project that provides context and instructions to Claude Code, Anthropic's AI coding assistant. Think of it as a README specifically for your AI pair programmer — it tells Claude how your project is structured, what commands to run, what conventions to follow, and what pitfalls to avoid.
When Claude Code opens your project, it automatically reads CLAUDE.md to understand your codebase. This dramatically improves the quality of suggestions, reduces errors, and ensures Claude follows your team's coding standards from the very first interaction.
Why CLAUDE.md Matters for Claude Code
🎯 Better Context
Without CLAUDE.md, Claude has to guess your project setup. With it, Claude knows exactly what framework you use, how to run tests, and what patterns to follow.
⚡ Faster Workflow
No more repeating "we use pnpm, not npm" or "run vitest, not jest" every session. CLAUDE.md persists your preferences across all conversations.
🛡️ Fewer Mistakes
Documenting caveats and conventions prevents Claude from making common mistakes like using the wrong import style or running incorrect build commands.
👥 Team Alignment
CLAUDE.md serves as living documentation that keeps every team member's Claude sessions consistent, regardless of who is working on the project.
CLAUDE.md Best Practices
Keep it concise
CLAUDE.md is read on every session. Keep it focused on what Claude needs to know — dev commands, structure, conventions. Avoid lengthy explanations.
Include runnable commands
Always provide exact commands (e.g., `pnpm run dev`, `pytest -v`). Claude can then execute them correctly without guessing.
Document the non-obvious
Focus on things that aren't apparent from the code: environment variable patterns, deployment quirks, naming conventions, import aliases.
Update it regularly
As your project evolves, keep CLAUDE.md in sync. Outdated instructions are worse than no instructions.
Use sections consistently
Standard sections (Overview, Commands, Structure, Conventions, Caveats) make it easy for Claude to find relevant information quickly.
CLAUDE.md Section Guide
| Section | Purpose | Required? |
|---|---|---|
| Project Overview | What the project does & tech stack | Yes |
| Dev Commands | How to build, test, lint, run | Yes |
| Project Structure | Directory layout & key files | Recommended |
| Coding Conventions | Style rules, patterns, import conventions | Recommended |
| Common Patterns | Recurring code patterns to follow | Optional |
| Caveats | Gotchas, known issues, sharp edges | Recommended |
| Key Dependencies | Important libraries & their roles | Optional |
Frequently Asked Questions
Where should I put CLAUDE.md in my project?
Place CLAUDE.md at the root of your project directory, alongside your package.json or go.mod. Claude Code automatically looks for it when opening a project. You can also have nested CLAUDE.md files in subdirectories for monorepo setups.
Is this tool sending my data to a server?
No. Everything happens 100% in your browser. Your project files are parsed locally using JavaScript, and the CLAUDE.md is generated from templates client-side. No data is ever sent to any server.
Can I use CLAUDE.md with other AI coding assistants?
CLAUDE.md is specifically designed for Claude Code by Anthropic. However, the format is standard markdown and the information is useful for any AI assistant. Some teams maintain similar files (like .cursorrules or AGENTS.md) for other tools.
How long should CLAUDE.md be?
Keep it concise — ideally under 200 lines. Claude reads the entire file at the start of each session, so shorter files mean faster startup and less noise. Focus on actionable information: commands, conventions, and caveats.
Should I commit CLAUDE.md to version control?
Yes! CLAUDE.md should be committed to your repository so every team member benefits from it. It serves as living documentation and ensures consistent AI assistance across the team.
What's the difference between CLAUDE.md and README.md?
README.md is for humans — it explains what the project is and how to get started. CLAUDE.md is for Claude Code — it provides machine-optimized context about your codebase structure, commands, and conventions that help Claude write better code.
Can I have multiple CLAUDE.md files in a monorepo?
Yes! Place a root CLAUDE.md with general project info, and add CLAUDE.md files in each package/app directory with package-specific instructions. Claude Code will read the most relevant one based on your current working directory.
