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
