Build Types
Nine build types on four engines. Pick the type before you describe the project — it decides what you end up with.
All build types
| Build type | You get | Engine | Shared as |

| Designs | Posters and graphics at fixed aspect ratios | Site Spec engine | Published page, print to PDF |
| Slides | A full-screen presentation deck | Site Spec engine | Published page, print to PDF |
| Documents | A paged report or proposal | Site Spec engine | Published page, print to PDF |
| Mobile Prototypes | An instant web app, or a React Native project | Sandbox engine / App Spec engine | A link, or a source download |
| 2D Games | A single-file playable game | Sandbox engine | A link |
| 3D Games | A Three.js world you move around in | Game Spec engine | A link |
| Animations | An animated, interactive scene | Sandbox engine | A link, recordable to video |
| Spreadsheets | A working sheet with live formulas | Sandbox engine | A link, CSV export |
| Data Visualizations | A dashboard of charts and KPIs | Site Spec engine | Published page |
The four engines
- Site Spec engine — websites, designs, slides, documents, data visualizations. The AI writes a validated specification; a fixed renderer turns it into the page. Publishable, editable section by section, and takes skills.
- Sandbox engine — instant web apps, 2D games, animations, spreadsheets. The AI writes one self-contained HTML program that runs in a sandboxed frame with no access to your account or the network.
- App Spec engine — cross-platform mobile apps. The AI writes a validated app specification; a fixed emitter turns it into a React Native + Expo project.
- Game Spec engine — 3D games. The AI writes a typed game definition that drives a Three.js runtime, then the game is play-tested in a browser.
