About WitPrompt: Prompt Checker for ChatGPT & Claude

WitPrompt underlines weak spots in your prompts as you type in ChatGPT, Claude, Gemini, and Grok. Every suggestion cites the provider's official documentation, not our opinion. Hover over an underline to see why it matters, then fix it with one click without losing your voice. The checker runs entirely in your browser. It only sends your prompt to our rewrite service when you request a full AI rewrite, which includes a preview diff and a plain-English summary of what changed and why. The Free plan includes 20 AI rewrites per day with no account required. Pro ($5/month) unlocks deep rewrites and includes 1,000 AI rewrites per day across up to three browsers. No API keys. No prompt storage. The only permission requested is local storage.
