Writefull provides AI language feedback, writing tools, and data insights for research writing. Its language models are trained on academic texts and suggest improvements to grammar, word use, style, and phrasing. Other tools can paraphrase, change style, split or join sentences, summarize or explain text, and generate titles and abstracts. 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. Writefull says it does not store users’ text, use text or interactions to train its AI, or sell data to third parties. Some features use third-party APIs, with user consent requested before text is sent.
