Userdoc is a software requirements workspace where AI does genuine specification work: it generates user stories, epics, and acceptance criteria, extracts functional specifications directly from existing source code across frontend, API, backend, and database layers, and creates full feature specs in hours rather than months. It also suggests requirements, generates user personas, and creates test cases from the same specification.
Extracting specs from existing code – not just generating new requirements from a prompt – is the capability that matters most for real engineering teams, where a large share of “requirements” work is actually reverse-engineering what an undocumented system already does before anyone can safely change it. Full change tracking, marketed as “Git for requirements,” brings the same version-control discipline engineers already expect from code to the specification documents that are supposed to govern it.
Userdoc reports client feedback from Infosys citing approximately 70% accuracy and relevance on AI-generated user stories – a specific, checkable figure rather than a vague quality claim. It targets enterprise companies, product managers and engineering leaders, and solo developers managing parallel projects. A 14-day free trial is available; specific pricing tiers are on a separate page.
