Notre FAQ

Yes, creating an account is completely free, and you get five pages generated at no cost to write your first document. For most simple functional requirements documents, that's enough. After that, we offer various subscription plans tailored to how often you need documents.

With a free account, you can create a limited number of documents. Our subscription plans then let you create an unlimited number of requirements documents and other professional documents—ideal for companies that regularly launch new projects.

Absolutely! Once your requirements document is generated, you can edit it directly in our interface or export it to Word for further customization. You keep full control over the content while benefiting from the professional structure and wording suggested by our AI.

For a standard functional requirements document, expect about an hour of dialogue with our AI. For more complex or detailed projects, it may take 2 to 3 hours at most—versus several days with traditional methods. The biggest advantage is that you only have to answer questions, without worrying about structure or wording.

That's exactly why DocGenius was built! Our AI guides you through the entire process, suggests appropriate wording, and ensures your requirements document meets professional standards—even if you've never written this type of document before. It turns your ideas and needs into the right technical language.
