Claude Code + Obsidian built a full neural network that runs at 98.16% accuracy in a browser tab No PyTorch. No notebook. 2 tools and 100,386 parameters. The split: Obsidian holds the brain on paper layer math, ReLU formulas, training logic, one vault Claude Code reads the vault and ships the engine WebGL, 3D, live inference You draw a digit on a 28×28 grid 784 pixels fire through 128 neurons, then 64, then 10 every connection a green or red thread you can grab and rotate Draw a 3, the probability bar slams to 100% The numbers: — 1,000,000 training images — 22,400 batches — 3 dense layers, nothing exotic — every single weight visible on screen Wrong guess? Trace it back to the exact neuron that fired Textbooks take 40 pages to explain backpropagation This takes 4 seconds and a mouse
