Userdoc

Userdoc is a software requirements workspace that uses AI to turn ideas, existing code and team knowledge into written specifications. It produces user stories, epics, non functional requirements, acceptance criteria, technical specs, test cases, user personas and user journeys, and tracks every change to a requirement in the manner of version control. It is aimed at product managers, business analysts and engineering teams who want clearly defined features before development starts, including teams that hand work to AI coding tools. A second use is reverse engineering: the product reads an existing codebase and generates functional specifications organized by feature and data flow, which helps teams document legacy systems. Userdoc also builds tech stack overviews, AI development plans and coding standards, and integrates with AI code editors, coding agents and development platforms. The vendor states it is SOC 2 Type II compliant. Pricing is per seat. A Free plan runs as a 14 day trial with one seat, one project and 10 requirements, with no credit card required. Lite costs $19 USD per seat per month for up to three seats and unlimited requirements. Pro costs $25 USD per seat per month, with no seat limit, unlimited projects, chat to requirements, export and platform integrations. Yearly billing saves 14 percent. Enterprise is a tailored plan with SAML2 and SSO, onboarding and training workshops, an account manager and SLA guarantees. Converting source code to documentation is priced separately by lines of code through an estimator on the pricing page.
