Longcat World is a free AI-powered 3D world generator that converts text prompts or images directly into interactive, explorable 3D environments at 24 FPS and up to 1080p resolution — all within a browser.
What is Longcat World?
Longcat World is a cloud-based platform that turns text descriptions or uploaded images into fully interactive 3D scenes you can explore in real time. It takes a text prompt (up to 800 characters with smart expansion) or an image, and outputs a playable 3D world with consistent lighting and physics. The platform runs entirely in the browser via cloud servers and is developed by the Longcat World team.
