  This tool finally helps me understand what makes a great prompt. It doesn't just give me a better version, it shows me to get there by analyzing why the original prompt is weak and showing what to improve. The difference this makes to the final AI output is incredible. An essential tool for getting more accurate and detailed results, Great Job!

  We built ModelRed because most teams don't test AI products for security vulnerabilities until something breaks. ModelRed continuously tests LLMs for prompt injections, data leaks, and exploits. Works with any provider and integrates into CI/CD. Happy to answer questions about AI security!
