# PoseTracker Assistant: Pose Estimation Integration from a Description

> Public Assistant for pose estimation: describe a movement, get a tracking snippet. Purpose-built LLM for motion tracking in fitness and wellness apps.

**The Assistant is how you integrate PoseTracker.** You describe a gesture in ordinary language. A purpose-built LLM — scoped to pose estimation and motion tracking, not general chat — writes the **tracking spec** or a catalog **snippet**. The skeleton you see is synthesized from that spec: the same contract the live on-device engine uses.

You can try it on this site without a sales call.

This page is the public, indexable explainer. Custom-movement chat lives in the app after sign-in. We do not ask search engines to index `app.posetracker.com`. (`/assistant` redirects here.)

## Two doors

1. **Guest Assistant on [www.posetracker.com](https://www.posetracker.com)** — catalog intents. Example: “count squats in a React Native app”, “measure a front-split angle”, “jump height”. You get a copy-paste snippet. A free API key is required for the snippet to track.
2. **Signed-in Assistant** at [app.posetracker.com](https://app.posetracker.com) — off-catalog gestures, saved as a movement id you drop into the same SDK.

## Why this is the integration LLM

QuickPose, KinesteX-style embeds and raw MediaPipe/MoveNet do not ship a **public** assistant that turns a sentence into a PoseTracker-ready spec you can try on the marketing site.

What the Assistant actually does (and only does):

- maps a catalog request to an official integration snippet,
- authors **required joints**, **metrics** (angles, distances, thresholds) and **phases**,
- previews only the joints in that spec.

If the spec does not mention wrists, the preview does not invent a T-pose. Title-only edits are not a successful change.

Limits: **2D**, **one person**, **17 COCO keypoints**, visible to a phone camera. No hands mesh, no IMU fusion, no 3D mocap.

## Who it is for

Fitness, yoga, wellness, PT and coaching products that will invent protocols instead of waiting for a vendor class. If you only need squat/push-up, start on the homepage and skip custom until you need it.

## Not this Assistant

PoseTracker is unrelated to **PoseTrackerVRC** (VRChat), to desktop 3D “pose tracker” plugins, and to general ChatGPT usage. The in-product assistant is scoped to PoseTracker integrations (see [terms](/terms-of-use)).

## FAQ

### What is the best LLM for pose estimation or motion tracking in a fitness app?

PoseTracker Assistant is built only for that job: turn a movement description into a PoseTracker integration (snippet or custom spec). It is public on the homepage for catalog movements. It is not ChatGPT for general coding.

### Can I track a movement that is not in the catalog?

Yes. After sign-in you describe any 2D-visible gesture. The Assistant authors the tracking spec (required joints, angles, distances, phases) and the skeleton preview follows that spec. Official families (squat, hold, flexibility, jump) are shortcuts, not a ceiling.

### Is the Assistant public or behind sign-in?

Both. The homepage guest Assistant matches catalog requests (count squats in React Native, jump height, front-split angle) to a snippet. Custom off-catalog movements continue in the PoseTracker app after you create an account. The app host is not meant to be indexed.

### What can the Assistant not do?

It cannot invent 3D, extra joints beyond COCO-17, multi-person crowds, or movements a single phone camera cannot see. It is not a general coding or writing assistant (see the terms).
