World builder

Build the place you'd like to meet

A camp on a mountain lake, a beach for the summer, a city to drive around. Build it yourself, or ask an AI to build it with you. No 3D skills needed.

  • Connect an AI agent such as Claude or ChatGPT, tell it what you'd like in the chat, and watch it build.
  • Over 3,000 models to place: houses, shops, cars, boats, furniture, trees and more. Drag to move, turn and stack them.
  • Paint grass, sand, stone and water, and shape hills, mountains, lakes and rocky shores.
  • Pick the sky and what reaches out to the horizon: forest, mountains, a beach, a city or snow.
  • Keep it private for your own rooms, or publish it for everyone to use and remix.

What's in a room

Everything happens in the room

Your avatar

Pick from 300 free avatars, or upload your own VRM. Everyone sees you walk, run, jump and wave.

Voice that feels near

Talk with your microphone; voices get quieter with distance, so you can split off into a corner.

Faces and expressions

Everyone's avatar shows face-on in a tile along the top, like a video call. Turn on face tracking and yours nods, blinks and talks with you, or show your camera instead.

Chat bubbles

Messages pop up over the avatar who sent them, so you always know who said what.

Made for phones too

A joystick under your thumb, a jump button, drag to look around. Upright or sideways.

Private by design

Voice, camera, chat and movement travel directly between browsers, encrypted. Rooms can have passwords.

Things to do

Sit on benches, lie on beds, open doors, and pick things up and put them down somewhere else. Everyone sees it.

Drive and sail

Hop in a car or onto bumper cars, take a canoe out on the lake, or float on a lilo. Friends see you go by.

Emotes and dances

Wave, cheer, clap or dance from the emote menu, a right-click or the number keys.

How it works

Three steps, about a minute

  1. Pick a world

    Press New room and choose where to meet: a mountain lake, a beach, a city, a funfair, a Japanese garden, or a world you built.

  2. Share the link

    Send the room's link to your friends. Add a password if it's just for you.

  3. Hang out

    Walk over, say hi, chat and talk. When everyone leaves, the room is gone.

Ready when you are
