Connect the defined features into a user flow,

and review the actual screens as you follow the flow.

You can directly review and validate the UX during the planning stage.

MCP compatible

Seamlessly integrate with MCP. Feed your Manyfast docs directly as context to start AI-powered development in Cursor or Claude Code immediately.

Real-time collaboration

Share documents with your team and collaborate in real time.
Keep your team aligned with instant access to the latest versions.

Security

Data Management Policy

Not used for AI training.

We technically block the use of customers' planning data for AI model training without consent.

Protects documents with encryption.

All planning documents are stored with field-level encryption, and the transmission period is protected by TLS 1.3.

Data by group is safely isolated.

With role-based access control (RBAC) and organizational unit logical isolation, there is absolutely no access to data from other groups.
