Study anything,
one topic at a time.
Ace turns a subject into a path — phases, topics, notes — and lets your AI teach straight from it.

Name a subject. Ace lays out the path.
A course, a certification, a language. Add your syllabus if you have one and Ace mirrors it — phase by phase.

Connect AI
Your AI, teaching from your curriculum.
One address. Paste it into Claude or ChatGPT, sign in once. It picks up where you left off, saves notes into the topic, and asks before marking anything covered.

Choose how you’re taught
Socratic. The tutor asks before it tells. Short, conversational turns that make you think, probe the words you use, and build prerequisites on the way.
Notes
Notes that live with the topic. Yours and your AI’s.
Write your own in a calm editor. Ask your assistant for visual notes and they land beside them — reread everything, cover to cover, in the type you like.
Phase II · Transformations
Matrix multiplication
Two moves, one after the other
A matrix moves every vector somewhere. Multiplying AB means: do B first, then A. That is the whole reason the order matters.
- Rows of A meet columns of B — multiply pairwise, add.
- (2 × 3) · (3 × 2) gives a (2 × 2). The inner sizes must match.
- AB ≠ BA in general. Rotating then stretching isn’t stretching then rotating.
Composition, not arithmetic — that’s the idea I kept missing.
