Notre FAQ

Yes, creating an account is completely free, and you get five free pages to create your first user manual. After that, we offer various subscription plans tailored to your documentation needs, whether you use it occasionally or regularly.

Absolutely! You can create as many user manuals as you need. Each project is saved in your personal workspace and can be edited at any time. For heavy users, our premium plans offer unlimited documents and advanced features.

Yes, every generated manual can be fully customized. You can edit the text, add your own images, change the layout, and even ask the AI to regenerate certain sections with new instructions. The document exported in Word format is also 100% editable.

For a standard user manual (20–30 pages), the entire process usually takes between 45 minutes and 2 hours. This includes your answers to the AI's questions and the document generation. For more technical or detailed manuals, expect 2 to 3 hours at most—compared to several days with traditional methods.

That's exactly what DocGenius was built for! Our AI guides you step by step, asking simple questions and suggesting tailored answers. It automatically handles the technical structure, consistency, and appropriate terminology. You simply share your knowledge of the product, and DocGenius turns that information into professional documentation.
