Bring your apps, games and agents to life with Mini avatars.

A Mini is a 3D chibi avatar built from a few lines of JSON, or from a selfie in about a second. Use one as a person in your product, a character in your game, or an agent’s face. Swift and web today; Expo coming.

Minimoji Avatar Demo

Our demo app

Give your status a voice.

Hold to talk, say what’s on your mind, and let your Mini tell the story.

Actual app screens, recorded with demo interactions. All previews are silent.

Looks, talks, reacts, idles.

Give it audio or text and it talks; give it a feeling and it reacts; point it somewhere and it looks; leave it alone and it idles. Nothing to animate by hand. Hover one and it notices you; click and it does it again.

looks
Eyes lead, the head follows. Point it at a cursor, a speaker, or a spot.
talks
Procedural jaw from audio, or a viseme timeline from your TTS.
reacts
Happy, surprised, laugh, smug, sad, angry — blended, not switched.
idles
Blinks, breathes, glances around. Leave a Mini alone and it stays alive.

Any Mini, from JSON.

Describe a Mini in a small document — one of about two trillion. The same document always rebuilds the same Mini, so it travels: a profile row, a URL, a body on the island.

Click any value and pick another.

{
  "v": 1, "seed": ,
  "head": , "skin": ,
  "hair": { "style": , "color":  },
  "eyes": { "color": , "shape":  },
  "brows": , "nose": ,
  "facialHair": ,
  "glasses": { "style": , "color":  },
  "hat": { "style":  },
  "ears": { "style":  },
  "extra": { "style":  },
  "blush": , "freckles": 
}

Open the playground

Every kind of face.

Skins, hair, beards, glasses, hats, earrings, headphones, freckles — everything composes with everything else. Move the cursor; they all follow it.

PreviewIn the two demos below, not the SDK.

And a body.

The same JSON, a whole figure: an outfit from its palette, a rig that walks, runs and jumps, and gestures from a word — wave, shrug, dab. Heads for a chat bubble, bodies for a world; plenty of apps only need the head.

Three figures, three gestures, each on its own clock.

Take one for a spin.

Open the island Run the course

Island and course need a keyboard for now; on a phone, try the party.

In your UI, not in a canvas.

Minis anchor to elements in your layout — a chat bubble, a player card, a contact row — and follow them through scroll and resize. No package at all? The HTTP API hands any stack a .glb and a .png.
