Notre FAQ

Yes, creating an account is completely free, and you get five pages generated for free to write your first design document. That's enough to test how effective our solution is on a medium-sized document. After that, we offer a range of subscription plans to fit your needs, whether for occasional or regular use.

With the free account, you can create one document limited to five pages. Our paid plans let you create an unlimited number of design documents, with different page limits depending on the plan you choose. You can also switch between plans as your needs evolve.

Absolutely! Once your document is generated, you have full control over its content. You can edit it directly in DocGenius or export it to Word for additional adjustments. Our platform is designed to be an assistant—you always stay in control of the final result and can tailor it perfectly to your technical requirements.

Most of our users write a standard design document in 45 to 75 minutes, compared to several days with traditional methods. The exact time depends on the complexity of your project and how detailed your answers are. For a highly detailed technical document, expect a maximum of 1 to 3 hours, with the option to take breaks and pick back up later without losing your progress.

That's exactly one of DocGenius's biggest strengths! Our AI is designed to guide even those who are less familiar with technical writing. It asks simple, clear questions, suggests appropriate answers, and automatically turns your information into a professional technical document with the right vocabulary and structure. You don't need to be a writing expert to get a high-quality design document.
