Mint
Built by Alex Carrabre and Tamrat Alemu, Mint is a chat-first 3D creation platform for generating, editing, and publishing interactive worlds built from Gaussian splats and 3D assets.
The Experience
Mint explores what it would feel like if creating a 3D world was as simple as describing an idea in natural language.
- Prompt-driven world creation
- Editable and playable 3D scenes
- Publishing and sharing directly from the browser
Instead of treating AI generation as a static output, Mint focuses on making generated worlds interactive, revisable, and usable inside a complete creation workflow.
How It Works
Users begin with a prompt, image, or reference set inside a chat-based interface. A spatial agent gathers intent, generates previews, supports revisions, and produces a final interactive scene.
Marble powers the core world-generation layer, producing splat environments, panoramic imagery, and collider data that are rendered and published through Mint Studio.
Stack
- Marble for world generation
- SparkJS + Three.js for realtime rendering
- React Three Fiber for interactive scene workflows
- Custom agent-driven creation and publishing systems
What’s Next
- More capable spatial creation agents
- Expanded editing and composition workflows
- Faster iteration between prompting, revision, and publishing
