Marble

Marble is an AI-powered platform that generates, edits, and shares high-fidelity, persistent 3D worlds from simple text prompts, images, video, or basic layouts using multimodal generative models; creators—artists, game designers, architects, and researchers—use it to rapidly prototype, iterate, collaborate on, export, and publish immersive environments without deep 3D modeling skills because the AI automates geometry, materials, and stylistic detail while still allowing manual refinement.
