TypoGuard

TypoGuard is an AI-powered Google Chrome extension that helps you write cleaner, more professional text directly inside the web tools you already use. It detects spelling and grammar mistakes in real time as you type — no copy-pasting into a separate app.

Inspired by Google's "Did you mean?", it brings smart, in-context correction to Gmail, ChatGPT, Claude, Google Gemini, Messenger, Google Messages, Airbnb and Booking Extranet, plus many other text fields online. Its engine is powered primarily by Gemini AI alongside other models.

TypoGuard is a desktop Chrome extension, not a mobile app. It's freemium: the free plan includes a set number of monthly corrections, while premium adds unlimited corrections, faster detection and more languages (English, French, Spanish, German and Greek).
