See how tech works by playing with it.

Hand-drawn, interactive explanations of the technology people use at work every day but rarely get to see inside. Each module is a short story you play through: build the thing, watch it break, fix it.

The pipeline you build, block by block, in the RAG module.

Why Tinker

Understanding comes from poking at things

Play, don’t just read
Every page has a live picture. Each step asks you to change one thing in it, and you watch what happens.
The real thing underneath
Nothing is faked for the animation. In RAG, real retrieval maths runs in your browser over real embeddings.
A story with stakes
You join a team with a problem to solve. Each chapter starts with something going wrong, and you fix it.

Module 2

In the workshop

The next concept is being built. Same idea: a story, a live picture, and the real thing underneath.

How it works

Every module plays the same way

1 Meet the problem
A short story sets up what is going wrong and why it matters.
2 Change one thing
The step asks for one action in the picture: add a block, move a slider, pick an answer.
3 Watch what changes
The picture, the meters and the answer update at once, so cause and effect are visible.
4 Fix it yourself
Puzzles hand you a broken setup. Hints appear when you’re stuck, and “Show me” is always there.
