Most browser AI demos consume a pretrained model. This one does the opposite: it trains a network from scratch, in the browser, on data the player generates by playing.

SnakeAI is a Snake game written from zero in plain JavaScript, plus a small neural network that learns to play by imitating your own matches. You play, every decision is recorded, a 739-weight network trains in seconds, and then it takes the controls.

The point is not that the snake moves on its own — a hardcoded script does that.
