Your AI engine for creating living, interactive 3D worlds that belong to you — generate, edit, publish and export, all in your browser.
No installs · No credit card · Free to start
From a sentence to a walkable, interactive world — Manifest handles generation, editing, physics and export so you stay in flow.
Describe a scene in plain words and watch a full interactive 3D world take shape — props, lighting, atmosphere and all.
Edit any world by chatting. Precise red/green diffs, one-click apply and undo — no clean structure ever broken.
Add colliders and a first-person walk mode instantly. Step inside your scene and explore it like a real space.
Turn any mesh into a rigged, animated character with a click — dozens of motions ready to drop into your world.
Export a self-contained HTML world that runs anywhere — what you test is exactly what you ship. No build step.
Your projects, your assets, your worlds — saved to your account, shareable on your terms, and yours to keep.
No 3D experience required. Manifest turns intent into interactive worlds — fast.
Type what you imagine — a neon night market, a chemistry lab, a racing circuit. Add images or sketches if you like.
The AI builds an interactive 3D world. Tweak it by chatting, add physics, models and animations until it feels right.
Share a clean link to the community or export a single-file world that runs anywhere — it's yours forever.
Real, interactive worlds built and published by Manifest creators. Click any one to step inside.
MANIFEST comes out of the University of Cambridge — one of the birthplaces of the very idea of a “world model”: a mind that carries a small-scale model of reality to imagine, predict and act.
If the organism carries a “small-scale model” of external reality and of its own possible actions within its head, it is able to try out various alternatives… and react to future situations before they arise. — Kenneth Craik, The Nature of Explanation, 1943
Kenneth Craik (1914–1945) — Fellow of St John's College, Cambridge, and first director of the Cambridge MRC Applied Psychology Unit. In The Nature of Explanation (1943) he proposed that the brain carries a “small-scale model” of reality inside the skull, using it to rehearse possibilities and react to events before they happen — the very origin of today's world models and internal simulation. In 1945 he died in a cycling accident on King's Parade, aged just 31.
Alan Turing (1912–1954) — Fellow of King's College, Cambridge (elected 1935, aged just 22). On Computable Numbers (1936) introduced the Turing machine, laying the theoretical foundation of computation; Computing Machinery and Intelligence (1950) asked whether machines can think and proposed the imitation game — the Turing test — founding the idea of artificial intelligence. Britain's national AI institute, the Alan Turing Institute, is named after him.
Two Cambridge roots — the world in the mind and the mind in the machine — meet in MANIFEST: an AI engine that turns words into living, interactive worlds.
