Rebuild as…
A flowchart, mind map or diagram on the board becomes one you can edit.
Handwriting → text
Your handwritten page becomes text you can search and ask.
Read with AI
Lecture slides in a PDF become text. Then Ask about this answers your questions about that file.
Flashcards from this note
A deck made from the note, ready to study.
Each of these uses credits, and shows its price before you tap it. Check what AI makes: it can misread a hand-drawn chart.
Flashcards
Cards that come back when they're due.
- Study shows the cards that are due first, the most overdue first, then the new ones.
- Again, Hard, Good or Easy sets when each card comes back, by spaced repetition (FSRS).
- A card you get wrong comes back before the study ends.
- Quiz tests you and gives your score.
- A card can carry a photo or an equation.
Math
Equations, step by step.
- A Math note is a list of lines: each one an equation or a sentence.
- On a phone or a tablet, an on-screen maths keyboard writes the equations. No LaTeX to learn.
- Number the lines as steps, and move them up or down.
- Equations also fit inside a simple note and on a flashcard.

- Answers come only from your notes, with the notes they came from.
- Ask across all your notes, in one notebook, or about one note or file.
- Each question shows its price before you ask.
- A thread keeps your questions together for 30 days after the last one.
- Search finds notes by words and meaning, a #tag or "a phrase".
