How to set up LM Studio

Load a vision-capable model, e.g. qwen/qwen3.5-9b, or google/gemma-4-e4b on a slower machine.
In the model's settings, turn off "Enable Thinking" so it answers quickly and doesn't run out of tokens before returning JSON.
Go to the Developer tab, turn on the server, and enable "Enable CORS". Without CORS this page can't call the API.
Enter the server address (IP or link) above and tap "Connect". The app automatically uses whichever model LM Studio is hosting — no need to pick one.

Camera off

Remove background (keep only the person) Runs on your device; a small model is downloaded the first time.

Connect to the LM server, then tap "Capture & check" or "Start monitoring".
