Structure before code

Map your app before you build it.

A free-form canvas for screens, blocks, and navigation. Export Markdown, .cursorrules, CLAUDE.md, or JSON for Cursor, Claude, and your toolchain.

Built for the handoff

Pages, blocks, and edges so your IA stays legible while you iterate.

Markdown specs and project rules ready for tickets, docs, or AI context.

Give models a single source of truth instead of a wall of chat history.

What you might copy out of a project.
