What is Writefull?
Writefull’s AI tools help students and researchers around the world to write better, faster, and with confidence. Overleaf and Writefull are both part of Digital Science, a company that drives global research progress through innovative, AI-powered technology.
Writefull doesn’t just copyedit research texts, it helps with a range of writing tasks, from choosing words and rephrasing sentences, to writing abstracts, and more. Using custom language models trained on published research, Writefull gives high-quality language support tailored to research writing. Even some of the world’s leading scholarly publishers use Writefull’s AI language edits.

Data privacy and responsible use
Is my text used to train AI models?
No, your project data and your interactions are not used to train AI models. Writefull trains its models on published papers, not on Overleaf project data. If you use Writefull features (such as the GPT language model or TeXGPT) that use a third-party service, such as OpenAI’s GPT model, your text is not used by that AI provider for training purposes.
Is my privacy protected?
Yes, your privacy and your projects are protected. Writefull never stores your text, nor does it use your text or interaction to train its proprietary AI models. Some of Writefull’s features (such as the GPT language model or TeXGPT) use a third-party service such as OpenAI’s GPT model. If you choose to use these features, your text may be sent to and temporarily stored by this third-party service provider, but will not be used for training their models. You’re informed before using Writefull features that involve third-party access, with explicit consent needed from you before your text can be sent to their servers. Your data is never sold to third parties or shared for advertising purposes. Please see Overleaf's privacy notice, and Writefull's privacy notice for more information.
If my text has been highlighted by Writefull, has an AI accessed my data?
When the language check is applied to your project, the language check model does not learn from your text. By default, the language check uses Writefull's language model to check your text, and Writefull never stores your text, nor does it use your text or interaction to train its proprietary AI models. If you choose to use the OpenAI's GPT model, your text may be temporarily stored by this third-party service provider, but your text is never used to train any AI.
The level of AI support you use is entirely up to you. You can use Writefull for a language revision only, or use the text rewriting/rephrasing features. Choose what feels right to you, and make sure to follow your institution’s or publisher’s policy on responsible use of AI technology.
I am not sure if my institution allows the use of AI. Can I use Writefull?
Writefull’s AI tools are designed to help you craft, rephrase, and improve your research texts. They are powerful tools, which should be used responsibly. Use them to explore different ways of expressing your thoughts and findings, but not to replace your own writing efforts.
Please make sure to consult your institution's policy on academic integrity to find out if these include guidance on the use of AI-assisted language tools or generative AI. If you can’t locate a policy for your institution, or if you have questions about it, it’s important to ask your professor or an academic advisor about institutional, departmental, and course-specific guidelines on using these tools.
