GrammarMe

GrammarMe

Translate text and fix grammar on any page, entirely on your device, using Chrome's built-in AI (Gemini Nano). Your text never leaves the browser — no servers, no tracking, no account.

What it does

  • Translate selected text

    Highlight text on any page, trigger GrammarMe, and read the translation inline. Language detection and translation run locally.

    Translator API

  • Fix grammar & spelling

    Correct grammar, spelling and punctuation without changing your meaning, tone, or language.

    Proofreader · Prompt API

  • 100% on-device

    All processing runs in Chrome via Gemini Nano. There is no server in the loop — your text is never transmitted.

  • Optional offline fallback

    If built-in AI isn't available, you can opt in to downloadable models. Model files come from Hugging Face — your text still stays local.

How it works

  1. 01

    Select text

    Highlight any text on any web page. GrammarMe reads only what you select, only when you ask.

  2. 02

    Trigger GrammarMe

    Click the floating icon or use a keyboard shortcut to translate or proofread.

  3. 03

    Read the result inline

    The result appears in a clean in-page bubble — computed locally, in milliseconds.

Privacy by design

Your text never leaves your device. No analytics, no telemetry, no ads, no account. The only optional network request is downloading offline model files — and only if you turn that on.
