for humans, not engineers
AI, levelled up
Six short levels that take you from "it's basically magic" to explaining agents, bottlenecks and prompting better than most people who talk about AI for a living. Every idea comes with an animation you can pause, step through and pull apart.
A taste of how it explains things
This is a real explainer from level 3. Press play, then hit X-ray to see what actually travels between the boxes when an AI "does something".

You → Assembler
Your words get packed
Plain code glues your message onto the system prompt, the tool list and the conversation so far.

What a computer is actually doing
A vending machine, a list of rules, and why software breaks so suddenly.
You leave able to: You can spot input → transformation → output in anything.
What a language model is actually doing
It finishes your sentence. Watch the odds, one word at a time.
You leave able to: You stop being surprised by hallucinations and 'it forgot'.
Traditional software + LLM = an agent
Open the loop, see the JSON, meet the boring code that does the real work.
You leave able to: You can explain what a tool is and who is responsible for actions.
Where it breaks: the real bottlenecks
Compounding errors, the cost staircase, context rot and trust.
You leave able to: You can tell a demo from a product in one question.
Prompt engineering is just being clear
Six sentences that turn a useless answer into a usable one.
You leave able to: You write briefs, not incantations - in your own words.
Saying the unsaid: vision, scope and taste
The gap between what you meant and what you typed, and how to close it.
You leave able to: You own a reusable brief and a four-line scope fence.
You can see it move
Every idea gets a scrubbable animation you can pause, step and x-ray.
No jargon tax
Plain words first. Terms only after you have already seen the thing.
Real machinery
The diagrams show the actual JSON and HTTP calls, not a marketing cartoon.
Honest limits
A whole level on where this stuff breaks, with the arithmetic to prove it.
Ready?
Level 1 takes about nine minutes and starts with a vending machine.
