Class notes that learn with you.

Capture lectures, slides, and ideas. Bella — your course-aware AI tutor — turns them into study guides, flashcards, and predicted exam questions. Granola and Notion don't know what class you're in. Bella does.

Get started — it's free See what Bella does

No credit card. Bring your own syllabus.

Lecture recording, transcribed

Hit record at the start of class. Timestamped transcript you can jump through, AI-cleaned notes when it ends.

Slide & whiteboard capture

Snap photos mid-lecture. OCR pulls the text and aligns each slide to the moment in the recording.

Course-aware everything

Notes live inside courses. Every AI feature sees your syllabus, lectures, and homework sets — not a generic LLM.

Bella, the tutor that knows your class

Ask Bella a question. She answers using your notes, your textbook, and your professor's emphasis.

Predicted exam questions

From your syllabus, lectures, and past homework sets, Bella predicts what's likely on the exam — with worked answers.

Syllabus → calendar, in one click

Upload a syllabus PDF. Get exam dates, Homework deadlines, and lecture topics on a calendar Bella can plan around.

AI study planner

Bella schedules your study blocks across courses based on difficulty, due dates, and where you're struggling.

Daily digest + learn ahead

Each morning: one interesting thing from yesterday's notes, plus a preview of what's coming up this week.

Flashcards, generated

Turn any note into a spaced-repetition deck. Drill what matters; the cards adapt to what you forget.

Meet Bella

The tutor that already did the reading.

Bella has read your syllabus, sat through your lectures, and graded your problem sets. Ask her to explain a concept and she'll use your professor'sframing. Ask for practice problems and she'll match the style of your last homework. Tell her you don't get something and she'll diagnose the gap, not lecture you.

Why did Prof. Lin spend so much time on Hermitian operators today?

Because the next two lectures are about the postulate that observables areHermitian operators — so spending 18 minutes on the spectral theorem today was prep, not a tangent. Want me to draft the bridge so it's ready when she gets there?

Yes. And quiz me on the spectral theorem.

On it. Q1: State the spectral theorem for a finite-dimensional Hermitian operator A. Why does it guarantee a real-eigenvalue eigenbasis?

Why not just use Granola or Notion?

Both are great tools. Neither was built for the rhythm of a college class.
