A motion language for LLMs

Give your LLM
a body.

Give your LLM the Posecode prompt. Posecode turns its response into structured, editable 3D human motion in your browser.

Open the playground →
Open source Runs on-device Prompt included
After pasting the Posecode prompt

Then ask: “Write a controlled superhero landing.”

Drop into the landing
01
LLM-native

Readable movement, not matrices.

02
Range-aware

Targets stay within configured ranges.

03
Browser-native

Live 3D, no server-side diffusion.

How it works

One prompt. Three clear steps.

  1. 01

    Ask

    Describe a representable movement.

  2. 02

    Generate

    A capable LLM writes a tiny .posecode file.

  3. 03

    Move

    The browser validates, constrains, and animates it.

Movement library

Ask for almost any move.

Explore launch-ready examples across fitness, rehab, dance, and more.

For developers

Open all the way down.
