ProWritingAid is a writing toolkit for storytellers that combines planning, writing, editing and publishing. It includes a grammar checker, writing reports, rephrasing, a plagiarism checker and analyses of chapters, plot, characters and whole manuscripts. The service works on the web, in desktop apps for Apple and Windows, in Microsoft Word, Google Docs and Scrivener, and through extensions for Chrome, Firefox and Edge, and it connects to tools such as Apple Notes, Notion, Atticus and Milanote. Some features use assistive AI.
ProWritingAid is owned by Orpheus Technology Limited, a UK company, so its data-protection supervisory authority is in the United Kingdom. According to its own GDPR page, all data is held on servers in the United States, outside the EU. The company lists third-party providers including Azure, Stripe, SendGrid, PayPal and Google. The software is not open source. For a European organisation, this means that text you submit for checking is stored outside the EU, under a UK-based operator.
