Four exhibits · zero servers
Machine intelligence you can put your hands on.
Every model on this site is built from scratch in a few hundred lines of TypeScript and trained live, on your machine, while you watch. Drag the data around. Break the learning rate. Watch it recover — or fail to.
The collection
Pick a room.
Each exhibit isolates one idea and lets you push on it until it breaks. Nothing is pre-recorded; if you reload the page, the model starts over from noise.
Neurons
Paint your own dataset, then watch a multi-layer perceptron carve a decision boundary through it. Real backpropagation, one frame at a time.
MLP · Adam · binary cross-entropy 02 — TransformersAttention
Type a sentence and see what every word looks at. Four heads, live queries and keys, and the softmax that decides who matters.
Self-attention · multi-head · softmax 03 — NeuroevolutionEvolve
No gradients here. A population of little brains drives into walls until, by selection and mutation alone, one of them stops.
Genetic algorithm · sensor networks 04 — Generative modelsDiffuse
Destroy an image with noise, learn to undo one step of that damage, then generate a brand-new one from pure static.
DDPM · forward & reverse processHouse rules
Nothing here phones home.
There is no backend. No account, no cookie, no analytics beacon, no third-party script, no font CDN. The server hands your browser a folder of static files and then has nothing further to do with you. Everything you type or draw stays in the tab and disappears when you close it.
That is not a marketing line — it is the reason this site can honestly claim to be safe. A site that never receives your data cannot leak it. The technical notes spell out the specifics, down to the exact security headers.
