You use AI every day. Do you know what it is doing?

An iOS app that takes the machine apart, one honest step at a time.

Neural Playground does not show you animations of AI. It runs real, tiny neural networks on your phone and lets you drag them around — so every number on screen is something the machine actually computed, including the times it fails.

How the lessons work

You bet first. Before you touch anything, you commit to a guess. Watching is passive; betting is not.
Then you find out. One picture stays on screen for the whole lesson while you push it around and see what really happens.
The maths is there if you want it. Every lesson keeps its formulas in a box you can open or ignore. The intuition never depends on opening it.

What is inside

A journey from a single artificial neuron to the attention mechanism behind ChatGPT.
Interactive labs for the classics — decision boundaries, clustering, overfitting, gradient descent, and more.
Deep Dive packs: whole lectures rebuilt as something you can play with, step by step.
