Turn a YouTube lecture into notes and flashcards
Paste the link. Stydra pulls the transcript, turns a two-hour lecture into an ordered study guide, and writes flashcards and a quiz from it. You get the content of the video in a form you can actually revise from — which watching it twice never gives you.
Pasting a YouTube link needs a free account, no card. The demo takes pasted text and needs no account at all.
How it works
- 01
Paste the video link
Any YouTube video that has captions — auto-generated ones count. Recorded lectures, conference talks, exam-board revision channels, a course playlist one video at a time. Nothing to install, and you don't need to download the video.
- 02
The transcript becomes structured notes
Not a wall of transcript. Stydra reorders it into numbered steps that follow the argument of the talk, lifts out the terms that got defined, and drops the filler — the bit where the lecturer talks about the room booking doesn't become a flashcard.
- 03
Revise from it, out loud if you want
Go straight into the deck, take the quiz, or open the voice tutor (a Pro feature) and talk the topic through with something that has the lecture in front of it. Explaining it back is how you find out which ten minutes you weren't following.
What you get
- An ordered study guide of the lecture, step by step
- Key terms with the definitions the lecturer actually gave
- Flashcards covering the whole video, not just the intro
- A quiz that explains what your wrong answer got confused with
- Spaced repetition, so the deck resurfaces what you keep missing
- A live voice tutor that knows the lecture's contentPro plan
- An audio recap — the ninety-minute video as a few minutes of reviewMax plan

Why re-watching at 2× doesn't stick
A lecture is delivered at the speaker's pace, not yours, and following along feels like learning because it's effortless — the ideas arrive already assembled. Nothing about that requires you to retrieve anything, which is why you can watch a lecture twice and still stall on the first exam question about it. Converting the video into questions forces the retrieval that watching skips.
Questions
Does it work on any YouTube video?
It needs captions or a transcript to read. Almost all lecture, course and educational content has them, including auto-generated ones. A video with captions disabled can't be processed — in that case, paste your own notes on it instead.
How long a video can it handle?
Full-length lectures are the normal case. Very long videos get trimmed to what fits in one pack, so a three-hour recording is better split into the sections you actually need.
Do I have to download anything?
No. It runs in the browser, and works the same on a phone.
Is it free?
The demo needs no account and no card. A free account adds saving, spaced repetition and sharing, with three packs a month. Paid plans lift the cap.
Can I use my own recording instead of a YouTube link?
Yes — you can record a lecture in the app directly, or upload the slides and your notes. The output is the same kind of pack.
Try it on the lecture you didn't follow
Paste the link and the lecture comes back as an ordered study guide with flashcards — a free account, no card. Or paste some text into the demo first, which needs no account at all.
