Userdoc

Userdoc is a web-based AI software requirements and documentation platform for professional development teams, consultancies, and project managers working on new projects, existing platforms, or legacy systems.

Key capabilities include:

• An AI scoping wizard to map user types, features, goals, and user journeys, turning discovery into structured requirements.
• Requirements management for user stories, epics, and non-functional requirements, with acceptance criteria and change tracking.
• Code-to-specs documentation, reverse engineering source code into functional documentation through a secure repository connection or ZIP upload to uncover existing features.
• Integrations with project management systems plus secure sharing with teams and stakeholders.

Pricing: pricing starts with a Lite plan at about $19/month, a Pro plan at about $25/month, an Enterprise plan around $499/month with custom options, plus a 14-day free trial and an optional one-time $499 code-documentation service.

What makes it notable is its focus on connecting requirements to technical documentation, including reverse engineering legacy code into feature-level specs, and its stated SOC 2 Type II compliance for security-conscious organizations.
