Notre FAQ

Yes, creating an account is completely free, and you get 5 pages included to write your first specification document. After that, we offer different subscription plans to match how often you need technical writing, with volume discounts for teams.

With a free account, you can create a first 5-page document. Our subscription plans then let you create an unlimited number of documents, with different page limits depending on the plan you choose. You can upgrade to a higher plan at any time as your needs grow.

Absolutely. Once your document is generated, you can export it as a Word file (.docx) and edit it like any other document. You keep full control over the final content. You can also return to the DocGenius interface to regenerate specific sections without losing your previous edits.

Most of our users finish their specification document in 45 to 90 minutes, compared to several days with traditional methods. The exact time depends on the complexity of your project and the level of detail required. For a complex project with many technical requirements, plan on about 2 hours at most, including your dialogue with the AI.

That's exactly where DocGenius shines! Our AI guides you step by step, asking the essential questions an expert would ask. It automatically structures your document to industry standards and suggests content tailored to your type of project. You don't need any prior technical writing expertise to create a professional document.
