Interactive AI lessons
See what the math is doing.
AI ideas explained with motion, sliders, and small honest models. Move a parameter, follow the animation, and build an intuition you can keep.

The lesson shelf
Start where curiosity takes you.
Each lesson is a complete experiment: a clear idea, a working model, and prompts that ask you to change something and predict what happens.
Gradient descent, step by step
Put a point on a loss curve and watch it roll. Learn why the learning rate can make the same idea crawl, settle, or fly off the chart.
Open lessonHow a model picks the next word
Inspect the probabilities behind a tiny language model. Turn the temperature up and see likely tokens share the stage with surprising ones.
Open lessonThe method
An intuition you can poke.
Reading about a concept gives you a definition. Changing one variable and watching the result gives you a mental model. These lessons are built for the second kind.
- 01
Watch the mechanism
Every lesson puts the actual computation on screen: a curve, a probability bar, a step that moves.
- 02
Change one thing
Sliders and presets isolate the variables that matter. You can see a concept fail, not just succeed.
- 03
Keep the model honest
Each lab names its simplifications. The tiny model is small on purpose, and the limits are part of the lesson.
No black box required
