Typlx

Privacy-first, open-source grammar checker. Advanced AI suggestions while your data stays under your control. No tracking.

Typlx adds AI-powered grammar and writing corrections to every text field in your browser: email, documents, forums, forms, anywhere you type. Unlike other grammar checkers, Typlx never sees your text. You connect the extension directly to the AI provider of your choice, or run a fully local model with no cloud at all.
