Writefull
What it is
Writefull is a writing support service for research writing, available on the web, Windows, macOS, and as a browser extension. Its language models are trained on academic texts and provide feedback on grammar, word use, style, and phrasing. Tools can paraphrase text, change style, split or join sentences, create summaries and explanations, and generate titles or abstracts. Writefull connects with Overleaf and adds LaTeX-focused language feedback, TeXGPT, and table and equation generators. A Microsoft Word add-in works with Windows, Mac, and Word Online. The Overleaf extension supports Chrome, Chromium, and Brave; Writefull Revise supports Chrome, Firefox, Safari, and Chromium-based Edge. Revise is limited to publishers and institutions and returns edits with Track Changes. A free plan costs nothing with limited language-editing and rewriting quotas.

The verdict
Writefull combines academic language feedback with rewriting and generation tools across browser, Word, and Overleaf workflows. Its free plan provides a limited starting point, while broader support requires plans with unlisted pricing.
Who it suits
