Test in your AI of choice
Type a rough prompt. Get a score, a diagnosis, a coached version, and export-ready buttons — no API key, no sign-in, zero cost.
This tool uses pattern-based rules to analyze your prompt — no AI, no API call, no waiting. The field badges update as you type to guide your rewrite. They’re a helpful signal to build your understanding of what makes an effective prompt, so you develop the instinct to write better ones every time you sit down with Claude, ChatGPT, or any AI — think of it as a coach pointing at the gaps, not a grade.
