Story mapHistory
In 1950 almost all of Africa is ruled from Europe. Only four countries govern themselves.
History: a story map
Who held what, moment by moment, with markers for where it happened and arrows for what moved.
Board
Say a topic.chalk draws the board.
What it is first, every term defined. Then pictures that move, in the subject’s own shape — and chalk walks you through them, out loud, one step at a time.
Every subject in its own shape
A history board isn’t drawn like a maths board.
Each subject gets the picture it is best taught with — and every number in it is computed: roots by the formula, prices where the curves really cross, values by running the code.
Graph storyMaths
With c = 2 the curve sits above the x-axis. It never reaches zero, so there is no solution.
Maths: a graph story
One slider moved at a time, and every mark it makes — here, the roots — worked out by the graph itself.
Graph storyEconomics
Where supply and demand cross, buyers and sellers agree: 6.4k tonnes at £4.86 a kilo.
Economics: the model, moving
Shift one curve at a time, and the new equilibrium is found where the lines cross — never worked out by hand.
Code walkPython
factorial(4) can’t answer yet: it needs factorial(3) first, so it waits on the stack.
Code: a program, walked line by line
chalk runs it, so the values and the call stack beside each line are the real ones.
SimulationBiology
In the dark, no bubbles: without light the pondweed can’t photosynthesise, so it gives off no oxygen.
Science: a system you push
Driven through states, each one saying why it changes — and plotted as it goes.

Boards teach
What it is first. Then why, how, and what it changed.
A board is built the way a good teacher explains: the idea in plain words and every term defined, before a single picture — then the reasons, the workings and the consequences.
- What it is, firstEvery board opens on the idea in plain words, with every term it uses defined.
- Then why, how, and what it changedCauses long and short, how it worked, and what came of it — not just what happened.
- Timelines that explainEach event says what led to it and what it changed, so the dates read as a chain.
The walkthrough
Next goes inside the block, not just to the next one.
chalk walks you through a board out loud, one step at a time — and a step can be a single moment on a map, a frame of a graph or one line of a program.
- Inside every blockA map’s moments, a graph’s frames, a program’s lines, a sim’s scenes, a passage’s notes.
- The camera followsIt flies to each block, and chalk’s cursor lands on the thing each step is about.
- Out loud, at your pacePause, go back, skip ahead. At a question, it waits for your answer.
The whole boardThree sections: how the community grew, the speech that began it, and what it changed. chalk takes you through.
Ask about any part
Circle it, highlight it, or press Ask.
Ask about exactly the part you mean. chalk knows what you picked — the blocks and words themselves, not a picture of them — and answers right there, on the same board.
- Circle, like on paperLoop three blocks and you mean those three; loop inside one and you mean that part. It stays held while you ask.
- Highlight a lineSelect any words and an ask bubble opens right beside them.
- Ask on any sectionEvery section has its own Ask, so a question about it lands in it.
Highlight
Select the words you’re stuck on
An ask bubble opens right there, already holding what you picked.
Ask
Every section has its own Ask
Press it and the question is about that section — the answer joins it.
Bigger goals
Learning a language? It offers you a course instead.
Some things don’t fit on one board. Ask to learn Spanish, or statistics from scratch, and chalk still starts your board — then offers to build a course: classes you come back to, each one a lesson you do.
Laid out for you
The model writes the lesson. chalk places every block.
chalk’s model describes sections, blocks and how they connect — never a position. When a section closes, chalk lays the whole section out in one pass: nothing overlaps, and the arrows are routed so they don’t cross.
Yours to keep
A board is something you keep.
Every board is saved, shareable by link and replayable — and drawn for the person learning, at their age and level.
Kept, and carried on later
Every board stays in your library. Open one next week, pick “Add to this one”, and it keeps building on the same board.
Shared by link. Replayed as drawn.
Send a view-only link. Replay rebuilds the board block by block, in the order it was drawn.
Pitched to whoever’s learning
Your profile goes with every board: a 10-year-old gets a picture story, a CS student gets code that runs.
Yours with no internet, too
Your boards live on your Mac, so every one you’ve made opens and plays through with no connection. Drawing a new one needs the internet.
