For product owners & developers
Posecode is a readable movement format with a parser, typed IR, Three.js renderer, web component, and LLM tools. Author it directly or with an LLM, then keep the result editable and under your control.
Ways to integrate
Keep the standard player, compose the lower-level libraries, or give an LLM movement tools.
Use the framework-free <posecode-player> web component with inline Posecode, a .posecode URL, or a share token.
<script src="https://unpkg.com/posecode-embed@0.2.2/dist/posecode-embed.js"></script>
<posecode-player src="/moves/squat.posecode"></posecode-player>Parse text into a typed, range-of-motion-clamped IR, then drive the Three.js renderer inside your own editor, lesson, or workflow.
npm install posecode-parser posecode-render threeThe npm MCP server runs over stdio on your machine. It teaches an MCP client the language, validates documents, and creates playground links.
npx -y posecode-mcp@latestWhere it fits
Load readable movement source, expose timing and joint values, and let a human revise the result instead of accepting a black-box clip.
Show an exercise beside a program or cue. Joint angles are clamped to general range-of-motion limits, but Posecode is not clinical advice or patient-specific validation.
Connect written instruction to a moving figure for anatomy, dance, physical education, or movement vocabulary.
Store small, diffable text files, validate them in CI, and open any movement in the browser without pre-rendering video.
Let an MCP-capable LLM write, validate, repair, and return a link to movement the user can inspect.
Use movement as editable content anywhere a video or static diagram is too rigid and a full animation pipeline is too heavy.
Available today
These pieces are in the public repository. The specification, parser, and share codec are Apache-2.0. The renderer, embed, and MCP server are AGPL-3.0 with a separate commercial option for closed-source product use.
posecode-embedA web component with lazy loading, controls, reduced-motion behavior, events, and inline, URL, or share-token inputs.
browserposecode-parserA TypeScript parser and CLI that produce typed movement data, diagnostics, and range-of-motion clamps.
npm + CLIposecode-renderA Three.js client-side renderer for a procedural figure or a compatible Mixamo-rigged GLB.
npmposecode-shareA dependency-free codec for URL-safe documents and playground permalinks. The document lives in the URL; this is not private cloud storage.

Exploring next
We are interested in working with a small number of design partners to learn which operational layer actually matters. Possible areas to explore include:
None of these capabilities is generally available today. There is no published commercial pricing. A design-partner conversation is for scoping the problem, constraints, and a possible collaboration. It is not a sales call for a service that already exists.
Bring a concrete problem
Tell us what you are building, where the animation would appear, and whether the open-source pieces cover the first version. We will reply from there.
