Notre FAQ

Yes, creating an account is free, and you get five complimentary generated pages to write your first design document. That's enough to test the service and produce a short document. For more complete documents, we offer different subscription plans tailored to your technical documentation needs.

With a free account, you can create an unlimited number of documents, but each is limited to five pages. Our subscription plans let you create an unlimited number of design documents and other technical documents with no size restrictions—ideal for teams managing several projects at once.

Absolutely. Your document can be exported in .docx format, so you can edit it in any word processor. You can also ask the AI to regenerate specific sections with new instructions, or add extra technical parts as your project evolves.

On average, it takes about one hour to generate a standard design document (20–30 pages) by answering the AI's questions. For more complex or highly detailed documents, expect a few hours of interaction with the assistant. That's significantly faster than the 3 to 5 days usually needed for this type of technical document.

Absolutely. DocGenius is designed to support both experts and non-technical users. The AI guides you with questions suited to your level of expertise and offers answer suggestions. You also benefit from proven templates and an optimal structure for your document, ensuring a professional result even without prior experience in technical documentation.
