In their own words
DeepL Write
DeepL Write is a writing assistant for revising text with corrections, alternative wording, rephrasing, and selectable styles and tones. It lists 19 writing languages. Users can access it through mobile and desktop apps, browser extensions, or integrations with Microsoft Word, Google Workspace, Microsoft 365, and AI agents. Extensions are available for Chrome, Firefox, and Edge; listed apps include Windows, Mac, Android, iPhone, and iPad. The free version includes 50,000 characters per user per month and one file translation per user per month, for files up to 5 MB. The Write Pro add-on costs €6.99 a month, billed annually with VAT included, and is available as an add-on to DeepL Pro Individual or Team. Team plans include administration, analytics and reporting, and single sign-on; teams can share a file translation limit or assign the same limit to each member. DeepL cites ISO 27001 and SOC 2 Type II certified processes and infrastructure. For Pro, content is temporarily stored only as technically needed, then deleted unless otherwise specified.
Writefull
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.
