Turn YouTube Videos Into Study Notes
Updated · By the Revizly team
Paste the link to a lecture or explainer video and Revizly turns it into study notes, organized by topic, in about 30 seconds. It works from the video’s captions, so you get the content of a 40-minute lecture without scrubbing back and forth to take notes.
Real example
Work by a Constant Force
What went in: A recorded physics lecture on YouTube, imported by a student.
suppose we have an object and we're applying a constant force in the horizontal direction we would now like to introduce the concept of work suppose our force starts at a point X I and goes to a position X final…
Revizly’s actual notes for that video. Formulas are written as plain text on this page.
The study guide
1. Work and Displacement
Memory hook: Constant force × displacement → work
- Work: the product of a constant force and the displacement of the object in the direction of the force.
- For a constant force in the x direction, the work done from the initial position to the final position is W = Fx Δx = Fx (x final − x initial).
2. Sign of Work
Memory hook: Force with displacement: positive work; force against displacement: negative work
- Work is a scalar quantity that can have a positive or negative value.
- Work is positive when the force and displacement point in the same direction and negative when the force opposes the displacement.
3. Work Units
- The SI unit of work is the joule, defined as one newton-meter: 1 J = 1 N·m.
4. Force–Position Graph
Memory hook: The work is the shaded rectangle beneath the constant-force line
- For a constant force, the work corresponds graphically to the area under the force-versus-position graph between the initial and final positions.

How to turn a YouTube video into notes
Sign in, paste the video link, and Revizly pulls the captions, cleans up the spoken transcript and turns it into notes organized by topic. Flashcards and a practice quiz come with it.
Spoken lectures are messy: “so, um, what we’d like to do now” doesn’t belong in your notes. Look at the excerpt above and the notes it became. Revizly drops the filler, writes out the definitions and formulas, and puts everything in order.
- Copy the link to the video from YouTube.
- Paste it into Revizly when you create a new class.
- Read the notes, edit them if you want, and test yourself with the flashcards and quiz.
What kinds of videos work best
Recorded lectures, explainer videos and review sessions with captions. The clearer the speaker, the better the notes. Music videos, vlogs and videos without captions won’t give you much to study.
- Recorded class lectures your professor posts on YouTube.
- Explainer channels for biology, chemistry, physics, psychology or history.
- Exam review videos for a specific course or unit.
What it costs
A YouTube import counts as one class, like any other upload. The free plan covers 2 classes a month. Essential ($6.99 a month) covers 20 and Premium ($9.99 a month) has no monthly limit.
Try it with your own class notes
Sign in, upload your lecture slides, a PDF, photos of your notes or a YouTube link, and Revizly builds a study guide, flashcards and a practice quiz in about 30 seconds. The free plan covers 2 classes a month.
PDF, photos, Word, PowerPoint or a YouTube linkYou can upload right after you sign inFrequently asked questions
Does it work with any YouTube video?
It needs captions, either uploaded by the creator or generated automatically by YouTube. Most lectures and educational videos have them.
Can I get flashcards from a YouTube video?
Yes. Every video you import comes with flashcards and a practice quiz built from the same transcript.
How long can the video be?
Full-length lectures work. Very long videos produce longer notes with more topics, so for a 3-hour review session it can help to split your studying by section.
Do I need an account?
Yes, you sign in with Google or email first. The free plan covers 2 classes a month.
What about videos in another language?
Revizly writes the notes in the language of the video. If you’re studying a language, the target language is kept as is.
