Userdoc

Userdoc provides a software definition workspace that uses AI to streamline what needs to be built and to uncover what already exists. It creates software specs from ideas, existing code, and team knowledge, so humans and AI tools build the right thing faster. The tool targets engineering teams, product managers, and stakeholders who need clear requirements and traceable documentation across projects and platforms.

Technical authorship and collaboration are central to Userdoc. It supports writing user stories, epics, non-functional requirements, and acceptance criteria, and it structures technical specs, test cases, personas, and journeys. It also includes full change tracking, described as Git for requirements, to keep history and changes auditable.

Userdoc surfaces the relationship between requirements and code, enabling AI-assisted development. It provides a tech stack overview, including how the UI and data layers relate to requirements, and offers features for understanding legacy systems and modernization planning.

It emphasizes converting source code into structured software knowledge that can be read and used by the entire team, including for AI-driven planning and development.
