Try AI, not just read about it
AI Labs turns core AI concepts into practical browser experiments. Inputs stay on your device, models are disclosed, and every experiment explains its limits.

- Runs in a Web Worker
- No text upload

The model is downloaded from its disclosed host and runs inside your browser. Your experiment input is not sent to Best-AI.org. The first use needs an internet connection, and your browser may cache model files for later visits.
