Notre FAQ

Yes, creating an account is completely free, and you immediately get five free pages to write your first specifications document. That's more than enough to test the solution on a real project. After that, we offer different subscription plans tailored to your documentation volume.

With the free account, you can create a limited number of documents. Our subscription plans unlock unlimited creation of functional specifications and other technical documents. Each plan also includes additional features such as real-time collaboration or integration with your existing tools.

Absolutely! You retain full control over your documents. You can edit directly within the DocGenius interface or export to Word format for additional adjustments. Our system also allows you to regenerate specific sections while keeping the rest of the document intact.

Most of our users write detailed functional specifications in about an hour, compared to several days with traditional methods. For more complex projects requiring comprehensive documentation, expect a few hours at most. The exact time depends on the complexity of the project and your familiarity with the subject.

That's exactly our strength! DocGenius is designed for business experts who aren't necessarily technical writers. Our AI will ask the right questions to extract your expertise and turn it into clear, professional functional specifications. You don't need any special skills in writing or document structuring.
