3D UML modeling studio

The Robot Drafts
architecture you can walk through

Model, connect, and export software architecture in an interactive 3D scene — a UML studio that runs in the browser, with nothing to install.

No account needed to look around: the studio opens on a demo draft that stays in your browser until you sign in.

What the studio gives you

A modeling surface built for systems that outgrew the whiteboard, and an interchange layer that keeps them honest against the code.

3D modeling canvas

Lay classes, packages, and services out in space instead of on a flat page. Depth, grouping, and color carry complexity, churn, and risk, so the shape of a system reads at a glance.

Import and export

PlantUML, Mermaid, and language code skeletons move in both directions, so a model stays reviewable as text in a pull request and round-trips back into the scene.

Versioned cloud saves

Every save is a version you can revisit and compare. Sign in to keep drafts in the cloud across machines, or stay logged out and work from browser-local storage.

Mockup studio

Describe an app in chat or voice. Screens, navigation, and clickable flows land on a 1920×1080 artboard — theme and Play stay in the View menu until you want them.

Keyboard-first workflow

The command palette reaches every action by name, and tool modes, menus, and camera framing all carry shortcuts — the mouse is for shaping the scene, not hunting through menus.
