Notre FAQ

Yes, creating an account is completely free, and you get five pages generated at no cost to write your first preliminary study. This starter offer is enough to test how effective our solution is on a simple document. For more complex studies or regular use, we offer subscription plans tailored to different usage volumes.

With the free account, you can create a document limited to five pages. Our subscription plans then let you create an unlimited number of preliminary studies and other professional documents, with a monthly page volume tailored to your needs. Your document history stays accessible at all times for edits or reference.

Absolutely! You keep full control over your document. You can edit the text directly in the DocGenius interface, ask the AI to regenerate specific sections, or export the document to Word for additional adjustments. All your changes are instantly integrated and can be reviewed by our AI to maintain the overall consistency of the document.

For a standard preliminary study (15–20 pages), the guided process usually takes about an hour of your time. More complex or detailed studies may require 2 to 3 hours of exchanges with our AI. This time only includes your interaction with the system—the document is generated and structured automatically. By comparison, traditional writing would take 3 to 5 days of work for an equivalent result.

That's exactly what DocGenius was built for! Our system guides you step by step, even if you've never written a preliminary study before. The AI asks you specific questions, suggests elements to include, and automatically structures your document to professional standards. You bring your industry expertise, and DocGenius turns your knowledge into a clear, complete, and professional preliminary study.
