Writefull integrates with Overleaf, offering LaTeX-tailored feedback, TeXGPT, and table and equation generators. Its Microsoft Word add-in works with Windows, Mac, and Word Online. The service is available on the web, Windows, macOS, and as a browser extension. The Overleaf extension supports Chrome, Chromium, and Brave; Writefull Revise supports Chrome, Firefox, Safari, and Chromium-based Edge. Revise returns edits through Track Changes and is limited to publishers and institutions. A free plan has limited quotas for language editing and rewriting.
