About Accio Prompt!

Accio Prompt! drops a small wand button directly into the composer of ChatGPT, Gemini, and Claude. One click rewrites your draft into a clear, structured, high-signal prompt — so the model gives you a better answer on the first try. WHAT IT DOES • Adds an "Accio! Optimize" button next to the send button on ChatGPT, Gemini, and Claude. • Rewrites your draft with a single tap — then shows you the original and the refined version side-by-side. • One more tap replaces the text in the composer. Nothing else changes. • Keeps a Spellbook of your recent optimizations, so you can revisit or copy a refined prompt any time. • Auto-refunds your credit if the spell fails — your credits are never lost. WHY IT'S DIFFERENT Most "prompt helpers" are a separate website where you paste, click, copy, paste again. Accio Prompt! lives where you already write. It opens a review modal right inside the chat composer, so refining a prompt takes less time than typing one. PRIVACY • The extension only runs on the four supported LLM sites (chat.openai.com, chatgpt.com, gemini.google.com, claude.ai). It does not run on any other site. • Only the text in the composer is sent to our backend when you tap "Accio! Optimize". Nothing is sent before you tap. • No browsing history is collected. • Sign-in is one-tap Google OAuth — we never see your password.
