Notre FAQ

Yes! Create your account for free and get 5 pages included—enough to write a complete technical proposal. After that, choose from subscription plans designed for freelancers, small teams, or enterprises. No credit card required to start.

Your free account includes one proposal. Our Professional plan offers up to 10 proposals monthly, while Enterprise plans provide unlimited document creation. Most users find they need 70% fewer hours per proposal, so they accomplish more with any plan.

Absolutely! You can modify any section directly in DocNexus before exporting, or download the Word document and make further edits. The AI-generated content is your professional starting point, not a rigid template.

Most users complete a 10-15 page technical proposal in about one hour. Complex proposals with detailed specifications might take 2-3 hours—still 5-7 times faster than traditional writing. The AI guides you efficiently through each section.

That's exactly why DocNexus exists! Our AI asks simple, clear questions and suggests professional language. You provide the technical knowledge; we ensure it's communicated clearly and persuasively. Even junior staff can create senior-level proposals.
