Watch Tutoro read your reasoning.
A live trace. Tutoro reads each step as you write, then picks up exactly where your reasoning turned — and teaches you from there.
Watch. Teach. Remember.
The whole product is built on these three behaviours. Everything else — the courses, the notes, the knowledge map — flows from them.
Watch.
No coach watching over your shoulder. Tutoro reads your handwriting in the background, parsing each step as you write it. We don't interrupt. We don't hint unless you ask.
Teach.
When you submit, Tutoro doesn't restart from "the formula is…". It picks up exactly where your reasoning bent — and walks you back through that single step in the language you used.
Remember.
Every session adds to a private map of how you think. Ask it anything: "what do I keep getting wrong in calculus?" Tutoro answers with citations to your own past work.
Your private knowledge map.
Every concept you touch becomes a node. Every connection your reasoning makes becomes a line. As you take more advanced courses, the map grows on its own — a personal Obsidian for everything you've ever studied.
We take the notes so you can think instead.
As you watch lessons and answer questions, Tutoro writes a private notebook in your name. Every concept lands as a linked card. Every mistake earns a margin note. Every link points back to where it came from.
Parametric derivatives
When a curve is given as x(t), y(t), the derivative is:

d/dt(cos²t). The answer was right, but watch for this — it'll bite on harder problems.Watched lesson 7. Three concept cards added: composition, inner derivative, common slips.
Skipped chain step. Margin note added to "Parametric derivatives" with link back to working.
New concept extracted: "implicit differentiation under substitution." Linked to existing nodes.
A real teacher writes it. Tutoro teaches it back to you.
Teachers author courses the way they always have — words, diagrams, exercises. Then Tutoro reads each lesson and delivers it personally to every student, drawing on what they already know and where they last struggled.
The chain rule, slowly.
Open with a picture: a function inside a function. Let students draw two nested boxes. Ask: "if you change the inner one, what happens to the outer one?"
Then introduce the formula. Don't rush it.
Three problems. Then the parametric extension.
Two sides of the same notebook.
Every screen, built to teach.

Honest answers.
Does Tutoro work without an Apple Pencil?
Yes — there's a typing mode and a Web build. But the experience is best with a Pencil because the model reads how you wrote it, not just what.
Will my handwriting actually be understood?
It learns your hand within the first few sessions. Even unusual notation, abbreviations, and personal symbols get picked up after a session or two.
What does "watch quietly" actually mean?
No hints unless requested. No popups. No corrections in the moment. Tutoro waits until you submit, then meets you exactly where you turned.
Can I delete my knowledge map?
Anytime, in full. We also let you export it (Markdown + Obsidian-compatible JSON) and re-import to a fresh account.
Is my work used to train models?
No. Your handwriting and reasoning are private to your account. Teachers see only their assigned classes.
