Extensions
Best AI Chrome extensions: pick by job, not hype.
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.
“Best” depends on the job. This page maps common AI productivity extension categories — and where a private prompt rewriter fits.
Category map
- Prompt libraries / packs — browse templates (e.g. AIPRM-style). Great for inspiration; weak for messy drafts you already wrote.
- Sidebar chat assistants — second chat next to the page. Useful; different from rewriting the composer itself.
- Prompt rewriters / optimizers — clarify the text in the box. That's RefineIQ: AI prompt enhancer, ChatGPT prompt optimizer, etc.
Why privacy belongs on the shortlist
Prompts contain work fragments and unshipped ideas. Prefer tools whose default is on-device / local AI — not “trust our policy.”
Install criteria checklist
- No account required for the core action.
- Works on more than one chat site.
- Transparent about where text goes.
- Keyboard + in-page trigger.
FAQ
What should I look for in an AI Chrome extension?
Clear job (rewrite vs generate vs sidebar chat), privacy default, whether it needs an account, and whether it works outside one chat site.
Does RefineIQ only work on ChatGPT?
No — ChatGPT, Claude, Gemini, Perplexity, Grok, AI Studio, and any text box, with per-site controls.
