Notre FAQ

Yes. Account creation is free, and you get five pages at no cost to write your first technical proposal. After that, subscription plans are available to fit different needs.

Absolutely. You can edit any section directly, or ask the AI to regenerate specific parts based on your instructions. You stay in full control of the final document.

That's exactly what DocNexus is built for. The AI asks you the right questions and structures your answers into professional prose. You bring the expertise; DocNexus handles the writing.
