AI Writer

Write better in any text box.
Reply faster on WhatsApp Web.

A free Chrome extension for grammar fixes, rewrites, translations and smart reply suggestions, powered by your own free AI key.

Add to Chrome

Works with Google Gemini, Groq or OpenRouter (all have free tiers).

✨

Rewrite anything

Improve, fix, shorten, expand, make formal or friendly, emojify or translate. See every change highlighted before you apply it, and undo with one click.

✔

Free grammar check

Spelling and grammar issues are counted on the ✦ button as you type. Fix them one by one or all at once. No key needed.

💬

Smart WhatsApp replies

Three reply suggestions in the chat's own language (English, Urdu, Roman Urdu, Hinglish…). Pick one, edit, press Enter. Nothing is sent for you.

🔒

Private by design

No servers, no analytics, no tracking. Your key stays in your browser. Codes, passwords, e-mails and links are hidden before chat text reaches the AI.
