Rosebud AI Alternative: Make a 3D World You Can Walk In

The difference is what comes back: not a sprite sheet, but a place you can walk through.

Liyue harbour, dusk. The lantern street from the top of the promenade — you walk in from here.

Want your own?Build My World

One sentence goes in. A place comes out.

Neta Studio is a world builder that runs in the browser. Describe a place and it writes the scene, the character, the camera and the controls, then publishes the result as a page. There is nothing to install and nothing to export — the link is the build. Keep talking to it to change the weather, move a landmark, or add someone else to walk beside you.

  • A character with a body. Third person, WASD or click-to-move, and a walk cycle that answers to the ground. Not a camera floating through a backdrop.
  • Ground that holds you. Colliders under the floor and edges around the place, so walking stays inside the scene instead of falling out of it.
  • The link is the build. Every world publishes to its own page. Send it and the other person is standing in it, on a phone or a laptop.

Questions people ask before they start

Is this actually 3D, or a flat scene with faked depth?

A real Three.js scene: geometry with normals and materials, a perspective camera, and a character whose position comes from walking on the ground. Orbit around a lantern and you see its back, which a painted backdrop cannot do.

Do I need to know code or an engine?

No. You write a sentence, and if something is wrong you say what to change instead of editing files. The output is still a normal web page, so a developer can open it later.

How is this different from Rosebud AI?

Rosebud turns a prompt into a 2D game: sprites, tiles, a game loop. This turns a prompt into a 3D place you walk through, with the camera behind a character. Both are one-sentence tools; the thing you get back is not the same object.

Can I move around it, or is it a video?

You move. WASD or the arrow keys, or click the ground and the character walks there. Drag to orbit, wheel or pinch to zoom. No clip is rendered in advance.

Can I share a world without the other person installing anything?

Yes. Every world is published as a page with its own link, and it opens in a browser on a phone or a laptop. Nothing to download, no launcher.

What if I actually wanted a 2D sprite game?

Then a 2D maker is the right tool and this page will not pretend otherwise. Come here when the thing you want to show is a place — a street, a room, a courtyard — rather than a rules grid.

Do I need an account?

You can look at any published world without one. Making a world and keeping it saved needs a Neta account.

Can I keep changing it after it is built?

Yes, in the same chat: ask for rain, a second landmark, another time of day. Publishing again updates the page the old link points at.

One sentence is the whole input.

Name a place. The camera drops in behind a character who can walk it, and the result is a page you can send.
