From idea to wireframe, all on one canvas. A seamless workflow.
PRD, feature specs, user flows, and wireframes all connect in one flow. No more jumping between tools, from writing to visualization.
One data source, flexible views
Features become flows, flows become screens. Your work continues without restart.
Document with multiple views
For structure, policies, or user flows, pick the view that fits and keep working.
Always in context
Managing everything on one canvas means changes stay aligned: no gaps, no conflicts.
Start from structure, not a blank slate
No more staring at empty Excel cells or blank Notion pages. We provide a systematic framework with all the essentials (requirements, detailed features, acceptance criteria) every product manager needs.
Visualize and document simultaneously: Tree view ↔ Directory view
Tree view for an at-a-glance structure, directory view for focused feature editing. Both views sync in real time, so you can switch based on your purpose.
User Flow and Wireframe Connection
Wireframes are automatically generated from your User Flow. Review the flow visually early in the process.
