Turn a YouTube video into a quiz you play

You paste the link, and that is the whole job. ZykoStudy fetches the video's transcript — its captions where they exist, an automatic speech-to-text pass where they don't — and feeds that text to the same question generator that handles your notes and PDFs. What you get back is a study set built from that specific video, not a generic question bank someone else wrote.

Because the questions come from the transcript, they track what the speaker actually covered. A fifty-minute lecture recording becomes a set you can play in a few minutes, which is a far better use of that hour than scrubbing back through the timeline hunting for the part you forgot.

A study set of practice questions written from the transcript, multiple choice by default, saved to your library next to the sets you made from notes and PDFs. You play it as any of the arcade games, and every answer feeds the same XP, levels and streaks, so a lecture video becomes something you can replay on a spaced schedule instead of a link you never reopen.

Read through the set before you rely on it. AI can misjudge what mattered in a video or write a weak wrong answer, so skim the questions against your own notes and edit or delete any that miss the point. A few minutes of checking is still far faster than rewatching the whole thing.

Anything where someone explains something out loud: recorded lectures, exam-review channels, a walkthrough of a problem set, a documentary you were assigned. The denser the spoken explanation, the stronger the questions that come out of it. Teachers can use a class recording or an assigned video the same way: generate a set, read the questions, and keep the ones that match what was taught.

Videos with no speech to transcribe — music, silent timelapses, pure b-roll — give the generator nothing to read, so they will not produce a set. Long videos are fine; they simply take longer to transcribe before the questions appear. Import only videos you have the right to use for your own studying, and keep sets made from someone else's video out of the public library.

Rewatching a lecture feels productive and mostly isn't. Video is a smooth, passive stream: it runs at the speaker's pace, every sentence arrives already familiar, and that familiarity gets mistaken for knowing it. Reviews and meta-analyses of study techniques generally find that retrieval practice — pulling an answer out of memory — beats passive review by a wide margin, and rewatching is passive review with a progress bar attached.

Turning the video into questions flips that around. You have to produce the answer before the game moves, so you find out on the spot which parts of the lecture never actually landed, while there is still time to fix them.

Every plan does. The free plan turns one YouTube video into a question set a month, alongside uploads of your own notes, slides and PDFs, ten AI study sets a month, and the core set of games — no card needed to start. The count resets on the 1st of each month, and Plus and Premium lift it entirely, so there is no cap on videos on either paid plan. Current plans and limits are listed on the pricing page.

If you would rather see the idea before deciding anything, paste a few lines of text into the notes demo for an instant sample quiz with no account at all. The video import is that same pipeline, with the transcript doing the typing for you.
