Write the way you already write. Then tap Distill, and SonaNote turns the page into a study kit — a summary, the key terms, flashcards on a proper schedule, a quiz, and a graded round of explaining it in your own words.
The page reduced to the points that carry it.
The ideas the note actually defines, each with its meaning.
Scheduled by SM-2 spaced repetition, so reviews land when you are about to forget.
Multiple choice drawn from the note, with distractors that are close enough to be worth thinking about.
Explain the idea in your own words and get it graded. The Feynman technique, marked.
Why it works
Highlighting a page and reading it again is comfortable and close to useless. What moves an idea into long-term memory is being asked to produce it — from a blank card, from a quiz, from having to explain it to somebody. SonaNote is built entirely around that: it takes the writing you were going to do anyway and turns it into the asking.
Every card carries its own interval, ease and lapse count. Cards you find hard come back sooner; cards you have earned drift further out.
Each note shows how deeply it has settled, banded from newly sketched through to etched. No red, no scolding — just what needs another look.
Point the camera at a textbook, a whiteboard or a handout. SonaNote reads the text, names the note, and can distill straight from the picture.
Drop a diagram exactly where it belongs in your writing and drag it where you want it. It stays anchored to its paragraph as you type around it.
Talk when typing is the wrong tool. Dictation keeps going through the pauses instead of cutting you off mid-thought.
See how the notes in a subject relate, and why — every link can name the term the two notes share.
Back up every topic, note, picture and review schedule into a single file, and keep it wherever you keep your own things. Restoring adds what is missing and never overwrites a note you already have.
Four themes across a paper world and a blackboard world, five typefaces, and a palette of chalk for colour-coding your subjects.
