Gemini

Gemini prompt optimizer that stays in your browser.

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.

This page is for people searching a Gemini prompt optimizer — RefineIQ rewrites the messy draft you already typed in Gemini into a clearer prompt, then you send it. Private by default. No account.

Why Gemini prompts still need a rewriter

Gemini is strong when the ask is clear. Half-formed prompts — buried questions, missing format, mixed goals — waste a turn. A dedicated prompt rewriting tool fixes the input before you hit send, so you spend fewer messages cleaning up.

How it works in the composer

  1. Select your rough prompt in Gemini (or focus the field).
  2. Click the Refine pill or press Alt+Shift+R.
  3. Review the rewrite, Replace in place, then send.

Privacy differentiator

  • On-device by default — local AI prompt optimizer; offline after one model download.
  • No RefineIQ server — nothing to phone home to.
  • Works everywhere — Gemini plus Claude, Gemini, Perplexity, Grok, and any text box.

FAQ

Does RefineIQ work with Gemini?

Yes. Select text in the Gemini composer (gemini.google.com / AI Studio) and use the Refine pill or Alt+Shift+R. Purpose-built support covers Gemini; it also works in any other text box.

Does RefineIQ send my prompts to a server?

Not in the default on-device mode. Inference runs in your browser via WebGPU (WASM fallback). There is no RefineIQ backend. Optional BYOK cloud mode sends text only to the provider you choose with your own key.

Is this a Gemini prompt generator?

No — it's a prompt optimizer / rewriter. You bring the rough draft; RefineIQ clarifies structure and wording while preserving your intent. For a blank start, dictate a Voice Draft then refine.

Is it free?

Yes. Free forever for core on-device refining — no subscription required.
