Best AI Chrome extensions: pick by job, not hype.
If everyone writes with AI, the edge is sounding like you didn't. RefineIQ rewrites your cold emails, investor pitches, cover letters, and posts so they read like a person and actually get noticed. CEO Mode cuts the AI slop so you stand out from the 99 that get ignored.
“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: a 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 that are clear about where your text goes and what it costs, and that don't keep or train on it. Rules you can check beat “trust our policy.”
Install criteria checklist
- Clear on what happens to your text (stored? trained on?).
- 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.
