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.

What you can do it

  • Write specs for a new project
  • Derive specs from an existing codebase
  • Document legacy systems
  • Give coding agents a detailed plan

Who it is for

  • Engineering leaders and product managers
  • Teams working on legacy systems
  • Teams using AI coding agents

What to watch out for

  • Storing requirements means deciding who can read them
  • Confirm current plan limits and pricing
