Is rewriting your notes worth it?

Usually not, and it is worth understanding why before you spend a Sunday on it.

Copying notes out neatly feels productive. There is visible progress, the result looks good, and you finish with something tidy. But copying is close to a mechanical task. You can do the whole thing while thinking about something else, and any study activity you can complete without thinking is not teaching you much. What it produces is a well-presented folder and the feeling of having studied, which is exactly the feeling to be suspicious of.

When it does make sense

Three cases justify it, and none of them is "so they look nice".

When you rewrite into a different form. Turning notes into questions, an outline, or a diagram forces you to decide what matters and how it connects. That is no longer copying, it is processing, and the processing is the learning.

When they are genuinely unusable. If your handwriting in class is illegible or you took notes in fragments, tidying them is necessary maintenance. Do it soon, while you still remember what you meant.

When you are going to share them. Notes for someone else have to be clean, and explaining something in writing is one of the most efficient ways to discover what you do not understand.

Outside those three, the same time spent on retrieval pays more: close the notes and try to tell yourself the topic without looking. That will show you in five minutes what copying does not show you in two hours.

The scheduling mistake

Most people rewrite notes at the worst possible moment — exam season, when time is most valuable and what is needed is retrieval practice rather than rearranging material.

If you are going to do it, do it in the same week as the lecture, while you still know what your abbreviations meant, and do it by turning the material into questions.

Digitising is a different question

Getting notes off paper and onto a phone has one real advantage, and it is not presentation: they become searchable. A notebook cannot be searched, and by the middle of term that matters.

Two honest warnings. Handwriting recognition is still uneven — clear writing in good light works reasonably, and fast lecture scrawl works much less well. And digitising for its own sake is the same trap as copying for its own sake, with extra steps. If you are about to photograph forty pages, decide first what you are going to do with them.

Where Quat fits

Quat is an iPhone and iPad app I make, so this part is an interested party talking — and the conclusion above does not change: if you want an app to rewrite your notes faster, the better answer is still not to rewrite them.

Where it does fit is the second case on this page, the one about converting them into a different form. You photograph the page, Quat reads the text and turns it into a note and cards that test you on it, stamped with where they came from. The output is not a tidy copy of your notes; it is a set of questions you can get wrong, which is the only thing on this page with a track record.

The photo and document allowance is twenty a month free and three hundred on a subscription, so photographing an entire notebook is not what the free tier is shaped for.

And the limit worth stating: with handwriting, results depend heavily on your handwriting. Try two pages before relying on it for a term.

What it will not do is guess. Where it cannot read a word it writes [?] rather than filling in something plausible, and the transcription lands in an editable field before it becomes anything. That matters more than the raw accuracy does: a word marked [?] is one you can fix in five seconds, and an invented one you never notice becomes a flashcard that drills something you never wrote.
