What Userdoc is
Userdoc is a software definition workspace. It creates software specifications from ideas, existing code and team knowledge, producing user stories, acceptance detail, non-functional requirements and technical stack descriptions so both people and AI coding tools have something concrete to build from.
A free trial is offered and SOC 2 Type II compliance is stated on the site.
