Notre FAQ

Yes, creating an account is completely free and you get five complimentary pages to write your first business case. That's enough to create a concise, high-impact document. For longer documents or regular use, we offer subscription plans tailored to different professional needs.

With your free account, you can create an unlimited number of documents, but with a total limit of five free pages. For more comprehensive business cases or regular use, our subscriptions let you generate unlimited documents with no length restrictions — ideal for professionals who regularly prepare decision-making materials.

Absolutely! Your business case is fully editable after generation. You can adjust the content, rephrase sections, add your own data or charts, and even ask the AI to regenerate specific sections with new instructions. The exported Word document remains completely editable for your final touches.

For a standard business case (10–15 pages), most of our users finish their document in 45–60 minutes. This includes answering the AI's questions and making any adjustments. For more complex documents requiring detailed financial analyses or in-depth market studies, expect 2–3 hours at most — compared to several days using traditional methods.

That's exactly our sweet spot! DocGenius was designed to support even people who have never written a business case before. The AI guides you with simple, contextualized questions, suggests professional phrasing, and automatically structures your document according to industry standards. All you need is knowledge of your project — DocGenius handles the rest.
