December 6, 2025•0 comments

Proofly is a free, open-source Chrome extension that gives you industry-class proofreading without sending a single word to the cloud. Powered by Chrome’s built-in on-device AI, it underlines issues as you type and fixes spelling, grammar, punctuation and more – all locally. No accounts, no tracking, works offline, and a lightweight, non-invasive UI that respects your page, your focus and your privacy.
