NotizAINotes from online courses that you can actually revise
Online lessons are easy to start and hard to revise. Paste the link of each lesson and keep a note, flashcards and a quiz in one course notebook.
Online courses, open lectures and YouTube series are often excellent. Their weakness is what happens afterwards. There's no handout, the slides aren't downloadable, and finding one explanation means scrubbing through hours of video. Making notes from online courses fixes that, and with NotizAI you don't have to pause the video every two minutes to write.
For each lesson on YouTube, paste the link into the course notebook. NotizAI works from the video's captions, writes a structured note and keeps the caption text in the transcript tab. Your YouTube lecture notes look like your other notes: headings, core points, key terms and pitfalls marked, with flashcards and a quiz attached.
MOOC notes work the same way when the course publishes its videos on YouTube with captions. If the course runs on its own platform behind a login, the videos can't be added by link, but you can paste the lesson's text or transcript into a typed note, or photograph the key slides.
Our example on this page is a linear algebra series on eigenvalues and eigenvectors, a topic where a well-made animated video can make something click that a textbook didn't. The note keeps the explanation; the quiz checks whether you can still tell an eigenvector from an ordinary vector a week later.
Keep one notebook per online course. As you work through it, the notebook overview gives you a summary of everything so far, which is useful when a course runs over many weeks and you take a break in between.
Linear algebra · Eigenvalues and eigenvectors (video series)
An eigenvector of a matrix keeps its direction when the matrix is applied; it is only stretched or shrunk.
Eigenvalue (λ): the factor by which the eigenvector is stretched, from A·v = λ·v.
To find eigenvalues, solve det(A − λI) = 0, the characteristic equation.
Remember: the zero vector is never an eigenvector, but an eigenvalue can be zero.
Watch out: a rotation in the plane (other than by 0° or 180°) has no real eigenvectors.
Watching actively
Videos invite passive watching at 1.5× speed. Before each lesson, read the note to know what's coming; during the video, pause at each key step and predict what comes next; afterwards, do the quiz. The note is what lets you watch with attention instead of transcribing.
Language learning with videos
Captioned videos in the language you're learning become a note plus the full caption text. Read the transcript for vocabulary, and paste a list of new expressions into a typed note to get flashcards for them.
Online courses alongside your degree
Many students use online lectures to fill gaps in their own courses. Paste a helpful video into the notebook of the university course it supports, so it's there when you revise for that exam.
How it works
Create a notebook for the course
One per online course or video series.
Paste each lesson's link
YouTube videos with captions, or public web pages.
Watch first, then read the note
Or read the note first and watch the parts you need.
Test yourself after each lesson
The quiz and flashcards are ready on every note.
Review with the overview
Catch up on the course so far after a break.
In your semester
YouTube lessons
Turn a playlist into a notebook of notes, one per video.
MOOCs
Keep notes from a multi-week course in one place, even with breaks in between.
Language videos
Captioned lessons give you notes plus the full caption text.
Preparing for a university course
Work through an online introduction before the semester starts.
Good to know
- Only YouTube videos with captions work. Live streams, Shorts and uncaptioned videos are not supported, and neither are other video sites.
- Course platforms behind a login can't be added by link; paste the text instead.
- The note is built from the captions, so formulas only shown on screen may be missing. Check the video for those.
Questions
How do I take notes from online courses?
Paste each lesson's YouTube link into a NotizAI notebook. It writes a structured note from the captions, with flashcards and a quiz.
Can I make notes from a YouTube lecture?
Yes, if the video has captions. Live streams and Shorts are not supported.
Does NotizAI work with MOOC platforms?
Only for videos published on YouTube with captions or public web pages. Content behind a login has to be pasted as text.
How do I keep notes from a long online course organized?
Use one notebook per course and add each lesson as a note. The notebook overview summarises the course so far.
Can I learn a language with YouTube and NotizAI?
Yes. Captioned lessons give you a note and the caption text, and you can turn vocabulary into flashcards.
Do I still need to watch the video?
Ideally, yes. The note helps you watch actively and revise later, but visuals and demonstrations are best seen in the video.
