Answer 5 questions about your project. Get an optimized CLAUDE.md that makes Claude Code actually understand your codebase.
30 seconds to generate. Works with Claude Code, Cursor, Codex, and Gemini CLI.
Every Claude Code user runs into this: you spend 20 minutes writing a CLAUDE.md, and Claude still doesn't understand your project the way you want it to.
You write a CLAUDE.md from an empty file every time you start a project. No templates, no best practices, no structure.
Claude ignores your conventions, picks wrong frameworks, generates code that doesn't match your stack. Your CLAUDE.md isn't specific enough.
You work on 3+ projects. Each needs different rules, different conventions, different tool configs. Managing them is a mess.
From zero to production-ready CLAUDE.md in 30 seconds.
Pick your language, framework, and project type. We'll ask about your testing setup, conventions, and deployment target.
Choose from 40+ proven rules: code style, error handling, security, testing patterns, and tool-specific settings. Or use our recommended defaults.
One click copies a complete, structured CLAUDE.md to your clipboard. Paste it in your project root and Claude Code instantly understands your codebase.
One command. Zero dependencies. Run it in CI to enforce config quality.

CLAUDE.md is a configuration file that sits in your project root. Claude Code reads it at the start of every session to understand your project's conventions, stack, testing setup, and coding style. A well-written CLAUDE.md dramatically improves the quality of Claude's output. Think of it as a project brief that trains your AI coding assistant.
Yes. The generator runs entirely in your browser. No account, no email, no limits. Generate as many CLAUDE.md files as you want. The Pro tier adds project saving, version history, and team features for people managing multiple projects.
Yes. ContextKit generates config files for Claude Code (CLAUDE.md), Cursor (.cursorrules), GitHub Copilot/Codex (AGENTS.md), and Gemini CLI (GEMINI.md). The core rules are the same; we adapt the format for each tool.
The best CLAUDE.md files have: (1) project architecture overview, (2) specific coding conventions (naming, error handling, imports), (3) testing requirements, (4) file structure guidance, (5) tool-specific settings like model routing and context management. ContextKit generates all of these based on your project type. Already have one? Score it with our free analyzer to see what's missing.
