Turn a YouTube lecture into study notes you can revise from.
Hour-long lectures are hard to skim and harder to revise from. Get the full lesson in the lecture's order, then a compact page of notes, with a tutor for anything unclear.
A statistics lecture, as a lesson and as notes.
Part of the lesson made from the first lecture of Richard McElreath's Statistical Rethinking 2023 (51 min), and the layout of the study notes you get.
0:00Introduction to the course
- A statistics course, sometimes joked to be an anti-statistics course, for scientists and students interested in natural entities and the forces that move them.
- Scientific models are often mathematical, but data and models are connected through statistics.
- The core interest is the science: how science motivates statistical reasoning and how it connects to data.
5:49What is causal inference?
- More than mere association between variables: it is the prediction of intervention and the imputation of missing observations.
- Correlation does not imply causation, and causation does not even imply correlation.
- Associations are bidirectional and contain no causes. They are purely statistical measures.
Study notes layout
After the lesson you can generate a short revision page with these sections: Summary, Key concepts (each with a timestamp), Code & commands, Steps / process, Gotchas & tips and Insights from your Q&A with the tutor.
From a long lecture to a revision page.
Read first, then compress.
Paste the lecture
A single lecture or a whole lecture series as a playlist. Any language; non-English lectures become English.

Generate notes, cards and a quiz
Get a compact notes page for revision, flashcards and a quiz. Ask the tutor about any section you didn't understand.
Made for revision, not just for reading.
Lectures are long. Your revision doesn't have to be.
Skim or study
Skip sections you already know, or read every line of the ones you don't.
Ask about anything unclear
Select a passage and ask for a simpler explanation, an example or a deeper dive.
Notes with timestamps
Every key concept links back to the minute it was taught, so you can rewatch just that part.
Take your notes with you
Your notes and your questions to the tutor are private to your account.
Free plan: 2 hours of video a week. Pro and Own Key plans are on the pricing section of the home page. For users aged 18 and over.
Questions, answered.
Does it read slides and whiteboards?
A Full lesson looks at the video as well as listening, so text, formulas and diagrams shown on screen can be included. A Transcript only lesson uses the speech alone.
How long can a lecture be?
Long videos work. How many hours you can add depends on your plan's weekly and monthly video hours.
Will it replace watching the lecture?
It can replace a first watch for many lectures. For anything visual, like graphs, use the timestamps to watch that moment.
Does it work for non-English lectures?
Yes. Public videos in any language become an English lesson.
Is it free?
Yes, the free plan includes 2 hours of video a week.
