Notre FAQ

Yes, creating an account is completely free, and you get five complimentary generated pages to write your first protocol. That's enough to test our solution and see the quality of the results. After that, we offer a range of subscription plans tailored to the needs of individual researchers, CROs, and medical institutions.

With a free account, you can create an unlimited number of documents, but with a limit of five generated pages free of charge. Our paid plans let you create an unlimited number of complete protocols and all your other clinical documents with no length restrictions. Choose the subscription that matches your research volume.

Absolutely. Once your protocol is generated, you can export it to Word (.docx) and edit it like any other document. You retain full control over the content. Plus, our interface lets you regenerate specific sections at any time if you want to make major changes to certain parts of your protocol.

With DocGenius, writing a standard clinical study protocol typically takes between 45 minutes and 2 hours, depending on the complexity of your study and how prepared you are. That's a dramatic reduction compared to the 40–80 hours usually needed to write a quality protocol. And most importantly: the result is immediately structured according to ICH-GCP standards.

That's exactly why DocGenius was built! Our AI guides you through simple questions and offers suggested regulatory wording tailored to your needs. You don't need to be an expert in writing or regulatory affairs to produce a protocol that meets the requirements of authorities and ethics committees. DocGenius builds best practices directly into your documents.
