Questions about Writefull
- Which AI model does Writefull use?
- Writefull runs (in part) on ChatGPT and Claude. Own language models trained on published articles, supplemented with OpenAI (GPT) and, in some features, Anthropic (Claude), both named by Writefull itself. The servers are in the Netherlands; Writefull states that it does not store texts and does not train on user input. Note: for the features that run through third parties, OpenAI and Anthropic temporarily retain the text (around 30 days).
- How much does Writefull cost?
- free version with a daily quota; Premium €19 per month, €46 per quarter or €135 per year (Dutch rate); group licences from 2 people. Check the current price on the provider's website; rates change often.
- Who is Writefull for?
- Writefull is aimed at research & science. It helps with tasks such as searching and exploring literature using semantic search and citation networks, screening titles, abstracts and full texts for systematic reviews, and extracting and summarising data and study characteristics from papers.
- What should I look out for with AI in research & science?
- Never use AI as a source: every reference must be traceable to the original article, as fabricated or wrongly attributed citations are the most common error. Unpublished data, research proposals and peer-review manuscripts are confidential or commercially sensitive, so do not enter them into a consumer account without a data processing agreement, and check whether the provider stores your input or uses it for training (publishers usually prohibit this explicitly for peer review). If you work with personal data from research participants, the GDPR and your own ethics review apply: running models locally or using an EU-hosted tool with data minimisation is then the safe route. Finally, document your search strategy and your AI use: journals and funders increasingly ask for this, and a review must remain reproducible.
