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. Use one as a person in your product, a character in your game, or the face of an agent. Web and Expo today; Swift coming.

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.

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.
