AI Lab: Browser AI & Simulations
5 toolsRuns in your browser
Small, honest AI experiments that run on your device: train, teach, play and explore how machines learn.
Browser AI & Simulations
- Neural Network PlaygroundTrain a small neural network in your browser and watch it learn.
- Gesture Predictor (Teach the AI)Draw swipes and shapes; the AI learns from your examples and predicts live.
- Fly Brain Simulator (Toy Model)A tiny spiking-neuron "fly" learns to steer toward food by reward.
- Connect Four & Tic-Tac-Toe vs AIPlay Connect Four or Tic-Tac-Toe against a minimax AI.
- Hugging Face Trends DashboardLive trending, most downloaded and newest AI models and Spaces on Hugging Face.
Learn how AI works by playing with it
The experiments in the lab are deliberately small. Each one is a few kilobytes of plain JavaScript that runs on your own device: no model downloads, no accounts, no servers doing the work behind the scenes. That makes them fast and private, and it means you can see exactly what is going on. The neural network playground shows gradient descent shaping a decision boundary in real time. The gesture predictor learns new shapes from a handful of examples. The fly brain simulator, clearly labelled as a toy model, shows a tiny spiking network learning to find food from a reward signal. The game AI plays Connect Four and Tic-Tac-Toe by searching possible futures.
The Hugging Face trends dashboard is the one exception that uses the internet: it reads public data from the Hugging Face Hub directly in your browser so you can follow which open models and demos are trending.
