PromptSharp

Rewrites your rough question into a fully-specified expert prompt before it reaches ChatGPT, Claude, Gemini, and more.

✨ PromptSharp — Turn rough questions into expert-level prompts, instantly. You know the AI chatbot in front of you can do incredible things — if only you asked it the right way. PromptSharp closes that gap. Type your question the way you'd normally think it — quick, rough, unpolished — and PromptSharp rewrites it into a clear, fully-specified expert prompt before it ever reaches the AI. No prompt engineering skills required. No separate app to open. It happens right where you already type. HOW IT WORKS A small ✨ Rewrite button appears directly inside the message box on the AI sites you already use. Type your question, click Rewrite, and watch it transform into a structured, detailed prompt — with the right role, context, and format — automatically. Then send it, exactly as you would any normal message. WORKS RIGHT WHERE YOU ALREADY TYPE PromptSharp adds a small Rewrite button directly inside the message box of the AI chat tools you already use every day. No copying and pasting between apps, no separate tool to open — click Rewrite, and your question becomes a fully-specified expert prompt right where you're already typing. FREE TO START Every new user gets free rewrites to try it out — no credit card, no signup friction beyond a one-time email sign-in. Once you've used your free rewrites, you have two ways to keep going: - Bring your own Anthropic API key — completely free, unlimited use, forever. Your key stays encrypted and local to your own browser; PromptSharp's servers never see it. - Or continue with a hosted plan for a simpler, no-setup experience. PRIVACY, BUILT IN FROM THE START PromptSharp only ever reads the text you're actively rewriting — nothing else on the page, nothing you haven't typed. Sign-in uses a simple one-time email link, no passwords to manage or leak. If you choose to use your own API key, it's stored encrypted, locally, in your own browser — never on our servers. Full details are available in our Privacy Policy. WHO IT'S FOR Anyone who's ever typed a quick question into an AI chatbot and gotten back a generic, disappointing answer — and wondered what they could have gotten if they'd just asked it better. PromptSharp does the "asking it better" part for you,
