Product context that keeps AI and teams building the right thing
Builds a shared vocabulary from your own docs so terminology stays consistent and AI tools stop assuming how your product works.
Stories keep decisions, feedback, implementation notes, usage analytics and feature flags attached so context survives beyond sprint planning.
Design decisions, investigations and code changes are captured on stories and picked up automatically by Claude, Cursor or Copilot.
Idea, roadmap, workflow, stories, bugs, flags and engagement live on the same object for a single connected workspace.
Requirements management and AI traceability for regulated engineering projects
Full requirements register with table, tree and network views, plus a System Breakdown Structure and allocation with review and agreed states.
REX is a free AI checker that scores requirements against the INCOSE 42-Point Guide, extracts them from PDF/Word/Excel and suggests clearer rewrites.
A stakeholder map and prioritised needs register, proposed breakdown structures and flow-down of requirements through the hierarchy.
An MCP server connects your live requirements project to Claude, Microsoft Copilot, ChatGPT and other MCP-compatible tools for grounded answers.
