A lesson built for your topic, not a video off a shelf
Sometimes the problem is not the question — it is the topic underneath it. Ask to be taught something and you get a short explainer that builds the idea up scene by scene, with the diagram drawn as it is explained.
What you actually get
Four to six scenes. Each one opens on something concrete rather than a definition, builds a single idea, and the last one checks the result against a worked number.
The diagram is drawn live alongside the explanation, and parts of it highlight as the explanation reaches them. You can pause on any scene, replay one step, or jump straight to the part you need.
Every subject has its own visual
Physics
Free-body diagram
The object, every force acting on it drawn to scale and angle, and the axes. Arrows light up as the narration reaches them.
Maths
Derivation, revealed line by line
Each line appears as it is explained, so you build the derivation rather than reading ahead to the answer.
Chemistry
Balanced equation
Reactants, products, and the conditions on the arrow — catalyst above, solvent below. Equilibrium arrows where the reaction is reversible.
Biology
Labelled figure
Structures composed from shapes with leader lines to their labels. Built from coordinates, never a copied image.
Computer science
Trace table
The code beside the values it produces, row by row, with the executing line highlighted as each row appears.
Writing
Argument map
The thesis, then each paragraph's claim and the evidence under it — because the usual fault is a claim with nothing beneath it.
A lesson can mix them. A chemistry topic that needs a rate equation will use the maths template for that scene, because the point is the clearest visual for the idea — not consistency for its own sake.
Why it is not video
Nothing is rendered to a file. A lesson is a small set of instructions — shapes, coordinates, labels, timings — and your browser draws it.
That is not a technical footnote. It changes three things you can feel:
It stays sharp. Pause on any scene at any size and the diagram is crisp, because it is being drawn, not replayed.
It loads immediately. A few kilobytes instead of a video download.
It improves without regenerating. When a diagram style gets better, every existing lesson gets better with it.
Built once, then instant for everyone
The first person to ask about a topic waits about a minute while it is written. Everyone after that gets it immediately.
Topics are matched on meaning rather than exact wording, so "explain centripetal force", "Centripetal Force?" and "what is centripetal force" all reach the same lesson instead of generating three near-identical ones.
Not finished yet
There is no spoken narration. Lessons currently play as timed scenes with the narration shown as text. The voice track is the next thing being added, and every lesson already carries its script — turning it on will not require rebuilding anything.
