Interactive explainers that take one hard idea in AI & make it something you can touch.

Why these exist

Learn AI visually.

Every lab takes a concept that is usually explained with a metaphor and replaces the metaphor with the thing itself. You type, drag, break it, and watch what happens.

Try clicking on one of the labs below.

How a language model actually works

Type a sentence and watch it become tokens, embeddings, attention and a prediction. The four stages, playable.

10 minBeginner

Gradient descent you can feel

Drag a ball down a loss surface. Change the learning rate and watch it overshoot, stall, or find the valley.

6 minBeginner

The tokenizer playground

Why “strawberry” has three r’s but the model cannot count them. Guess the token count and see what it costs.

4 minBeginner

Why models hallucinate

Break a retrieval pipeline on purpose. Watch a confident, well-formed, entirely invented citation appear.

8 minIntermediate

Diffusion: noise to image

Scrub the denoising steps back and forth and see a picture emerge out of static.

7 minBeginner

The map of meaning

Every word is a place. Run king − man + woman, and find out why “bank” is a problem.

6 minBeginner

The machine that memorises

Draw your own data, then watch a model fit it perfectly — and fail completely on the next sample from the same source.

6 minBeginner

Where’s the line?

Draw the boundary between two classes by hand, then let four algorithms draw theirs. Scored against held-out data.

7 minBeginner

Ship it, or don’t

One slider decides who gets flagged. Watch false positives trade against false negatives, with the human cost written underneath.

6 minIntermediate

Attention, head by head

Sixteen heads, one sentence. Find the head that learned grammar, and the ones that learned nothing at all.

9 minAdvanced

Spot the fake

Twenty rounds of real against generated. Score yourself, then find out which tells actually work and which do not.

5 minBeginner

What a filter sees

Drag a small grid of numbers across a photograph and watch edges, blurs and textures fall out of arithmetic.

7 minBeginner

Break the assistant

A support agent with tools and secrets. Six levels. Get it to do something it was explicitly told not to.

12 minIntermediate

The reward hacker

Write the rule you want followed. Watch the agent satisfy it exactly, and miss the point entirely.

8 minIntermediate

Find the groups

Place the cluster centres yourself, then let k-means take over. Change k and watch the “right answer” change with it.

5 minBeginner

One new lab ships a month, and the order is set by what people ask for. Tell us which you want next.

After the labs

Playing with it is an hour.
Building it is 6 months.

Every lab is a five-minute version of something you construct properly in the programme, tokenisers, attention, retrieval, evaluation, deployment.
