Free tools
Free AI tools: start with a private prompt optimizer.
RefineIQ is a privacy-first Chrome extension that rewrites rough AI prompts into structured, detailed prompts for ChatGPT, Claude, Gemini, Perplexity, Grok, and any website text box. All processing happens locally in your browser, with no accounts and no RefineIQ servers.
If you're scanning lists of free AI tools, look for ones that don't require an account to do the core job — and that don't upload your drafts by default.
RefineIQ on that list
- Free prompt optimizer — rewrite, don't subscribe.
- Local / offline AI extension after one download.
- Private AI extension — no RefineIQ backend.
- Works as an AI productivity Chrome extension across ChatGPT, Claude, Gemini, and any text box.
Compare jobs, not logos
Template browsers, chat UIs, and rewriters solve different problems. See AIPRM and PromptPerfect comparisons if you're migrating.
FAQ
Is RefineIQ really free?
Yes — free forever for core on-device refining. No paid plan required. Optional tip jar in the popup is the only monetization.
Any catch with “local AI”?
One-time model download (~380 MB default, lighter tier available). After that, offline refine works with no RefineIQ server.
