The lecture summary

Getting to the end of a sixty-slide PDF with nothing in your hands is what happens when you study alone. The summary is that page: what was explained, sorted by topic, at a length you actually read.

When it gets built

It builds itself when you finish the lecture, as soon as the last slide has been explained. If you practise before finishing, it is ready up to where you got. In the meantime, the card on the document page tells you how many slides are left.

It is built in the background, and it gives way to any slide you are waiting for: the summary can take a little longer, the lecture you are listening to cannot.

By topic, not by slide

A slide number is not an index of anything; topics are. So the summary gathers what was explained on each slide and sorts it by topic. It has to draw on every slide, and the model is not taken at its word on that: it gets counted, and any slide left out is asked for again. Slides with no text, like a photo or a diagram without words, are not required.

If you use class notes, the summary reads them too. And changing a note does not rebuild it from scratch: it reads what is new and adds whatever it contributes.

Reading it or listening to it

It lives on the document page, above the notes, and opens to the side like a note you cannot edit. The card tells you how many topics it has and how long it takes to read.

With Listen, Mina reads it topic by topic in the lecture's voice, and each word lights up as it is spoken. Tapping a heading starts that topic, and tapping a line jumps to its first word.

With Copy it comes out as text, ready to paste into Notion or your notebook.
