Context-aware

Your AI prompt enhancer reads the whole thread, not just the last line

Mid-chat follow-ups like "make it shorter" get rewrites that reference what you were already discussing — the feature most prompt tools skip.

How context capture works

Same idea. Better prompts.

A real before-and-after from the AI prompt enhancer — vague input in, specific rewrite out.

AI prompt enhancer FAQ

An AI prompt enhancer is a tool that analyses the prompt you are about to send to a large language model and rewrites it to be clearer, more specific, and easier for the model to answer well. AI Prompt Fixer is a free AI prompt enhancer that lives inside ChatGPT, Claude, Gemini and Perplexity, scoring your prompt in real time and offering a one-click rewrite.
Yes — and this is what makes AI Prompt Fixer different. When you refine a prompt in the middle of an existing chat, the extension captures up to the last 6 conversation turns (capped at 8,000 characters total and 2,000 characters per message) straight from the page DOM and passes them to our router. The optimizer uses that history purely as context — it never answers or summarises it — so a vague follow-up like "make it shorter" becomes a precise rewrite that actually references what you were just talking about. The feature is on by default and can be toggled off from the extension popup at any time.
Yes. The browser extension and the web demo are free to use. A Pro tier is on the roadmap for teams that need cloud sync, shared prompt libraries and higher API limits, but the core AI prompt enhancer will stay free forever.
The browser extension currently runs on ChatGPT (chat.openai.com and chatgpt.com), Claude (claude.ai), Google Gemini (gemini.google.com) and Perplexity (perplexity.ai). There is also a native VS Code and Cursor extension for coaching prompts from inside your editor. The underlying prompt quality signals are universal, so they work for any large language model you copy prompts into, including Midjourney, Stable Diffusion, GitHub Copilot and Cursor.
