Free AI Tools for Developers
Free tools to supercharge your AI coding workflow. Generate rules, analyze prompts, and optimize your interactions with AI assistants.
These free AI tools help you get more out of Cursor, Claude, ChatGPT, and other AI coding assistants. Whether you need to generate a project-specific .cursorrules file or analyze your prompts for clarity and effectiveness, each tool is designed to save you time and produce better results — no signup required.
Every tool runs entirely in your browser. Your prompts and configurations stay private and are never stored on our servers. Use them as standalone utilities or alongside HyperPrompt's prompt library and rules directory for a complete AI workflow.
Cursor Rules Generator
Generate optimized .cursorrules files for your project in seconds. Configure your tech stack, coding standards, and AI behavior.
AI Prompt Grader
Analyze your prompts for clarity, specificity, and effectiveness. Get actionable suggestions to improve your AI interactions.
Why Use AI Developer Tools?
AI coding assistants like Cursor, Windsurf, and Claude produce better output when given clear instructions. A well-configured rules file tells the AI exactly how to write code for your project. A well-structured prompt eliminates ambiguity and gets you production-ready responses on the first try.
Most developers spend time iterating on prompts and debugging AI suggestions that don't match their codebase conventions. These tools front-load that effort — generate rules once, grade your prompts before sending them, and spend less time correcting AI output.
How These Tools Fit Your Workflow
- New project? Use the Rules Generator to create a
.cursorrulesfile in under a minute - Prompt not working? Run it through the Prompt Grader to find weak points
- Need inspiration? Browse the prompt library for pre-tested templates
- Want community rules? Check the rules directory for 500+ configurations
