AI Coding Rules Generator
Generate config files for Cursor, Claude Code, Windsurf, and GitHub Copilot from a single form.
Step 1: Language & Framework
Step 2: Coding Conventions
Step 3: Quick Presets
Step 4: Custom Rules
Add one custom rule per line. These are appended to the generated output for all formats.
.cursorrules
You are an expert TypeScript + React developer. Always follow these rules when generating or editing code. Language: TypeScript Framework: React Indentation: 2 Spaces Naming convention: camelCase Rules: - Use functional components with hooks - Prefer named exports for components - Colocate styles, tests, and types with components - Use type hints and annotations for all function signatures - Prefer functional and declarative patterns over imperative code When writing code: - Follow the project conventions above - Keep functions small and focused - Use meaningful variable and function names - Add comments only for complex logic, not obvious code
How to Use This Tool
- Select your programming language and framework from the dropdowns. The framework options update automatically based on your language choice.
- Choose your coding conventions: indentation style, naming convention, and toggle options like type hints, functional patterns, and testing.
- Or use a Quick Preset to instantly configure everything for popular stacks like React + TypeScript, Python + FastAPI, or Go.
- Add any custom rules specific to your project in the text area — one rule per line.
- Switch between the four output tabs to preview each format: .cursorrules, CLAUDE.md, .windsurfrules, and copilot-instructions.md.
- Click Copy or Download on each tab to get the file ready for your project.
Why Every AI Coding Project Needs Configuration Files
AI coding assistants like Cursor, Claude Code, Windsurf, and GitHub Copilot are powerful — but without project-specific configuration, they make assumptions about your code style that may not match your team's conventions. A configuration file tells the AI exactly how to write code in your project.
The fragmentation of AI coding assistant config formats is a real problem in 2026. Cursor uses .cursorrules, Claude Code uses CLAUDE.md, Windsurf uses .windsurfrules, and Copilot uses copilot-instructions.md. If your team uses multiple tools, you need all four files to stay in sync. This generator creates all formats from a single set of inputs.
Effective AI coding rules should cover: your tech stack and versions, naming conventions, preferred libraries and patterns, error handling requirements, testing expectations, and any project-specific constraints. The generated rules follow best practices from the community and adapt to your specific language and framework.
Pro tip: commit these files to your repository so every team member gets consistent AI-generated code. Update them as your project evolves — especially when adding new dependencies or changing architectural patterns.

FAQ
What formats does this tool generate?
This tool generates configuration files for four AI coding assistants simultaneously: .cursorrules (Cursor IDE), CLAUDE.md (Claude Code CLI), .windsurfrules (Windsurf IDE), and copilot-instructions.md (GitHub Copilot). All formats are generated from the same inputs.
Where do I place these files?
All four files go in the root directory of your project. Cursor reads .cursorrules, Claude Code reads CLAUDE.md, Windsurf reads .windsurfrules, and GitHub Copilot reads copilot-instructions.md from the .github folder.
Can I use multiple AI coding assistants?
Yes! Many developers use 2-3 AI coding assistants. Having all configuration files ensures consistent code generation regardless of which tool your team members prefer. Generate all four formats at once and commit them to your repository.
What is CLAUDE.md?
CLAUDE.md is the configuration file for Claude Code, Anthropic's AI coding CLI tool. It uses Markdown format with sections for project context, tech stack, conventions, and rules. Claude Code reads this file from your project root to understand how to write code for your project.
How is .windsurfrules different from .cursorrules?
Both serve the same purpose but for different IDEs. .windsurfrules is for the Windsurf AI IDE (by Codeium) and uses slightly different phrasing optimized for Windsurf's AI engine. .cursorrules is for Cursor IDE. The core rules are the same, but the formatting adapts to each tool's expectations.
