Notre FAQ

Yes! Create your account for free and get 5 pages to write your first requirements document. See exactly how DocNexus transforms your documentation process. After that, choose from subscription plans designed for individual professionals or entire teams.

Your free account includes enough pages for a complete requirements document. With a subscription, create unlimited documents—from quick requirement updates to comprehensive 100+ page specifications. Most users create 10-15 documents monthly.

Absolutely! Every section is fully editable. Add your specific technical details, adjust stakeholder requirements, or refine acceptance criteria. DocNexus provides the structure and content foundation—you add the finishing touches that make it uniquely yours.

About 1 hour for a standard requirements document (10-20 pages). Complex technical requirements with multiple stakeholders might take 2-3 hours. Compare that to the typical 3-5 days for traditional writing—that's an 80% time savings.

That's exactly why DocNexus exists! The AI guides you through every section with targeted questions and examples. It ensures you cover all critical areas: functional requirements, non-functional requirements, constraints, assumptions, and acceptance criteria. Write like a senior analyst from day one.
