From Watch Time to Study Time
QuerySpark turns lecture videos into the study materials you actually need -- quizzes, flashcards, and notes -- in seconds.
Just Paste the URL
No downloading, no transcribing by hand. Paste a YouTube lecture link and QuerySpark reads the transcript and gets to work generating questions in seconds.
Quizzes with Answer Keys
Get MCQs, true/false, short answer, and essay prompts tagged by Bloom's level -- each with an answer key and explanation drawn straight from what the video actually said.
Flashcards & Study Guides
Beyond quizzes, turn a video into a clean set of flashcards and a structured study guide -- so a one-hour lecture becomes review material you can actually drill.
Active Recall, Not Passive Watching
Watching a lecture feels productive but fades fast. Converting it into questions forces active recall, the study technique research consistently shows beats re-watching.
Built-In Spaced Repetition
Questions from your videos feed into a spaced-repetition schedule, resurfacing them right before you'd forget -- so the lecture sticks for the test, not just for the day.
Export to Anki, CSV & PDF
Already have a study workflow? Export your video-generated cards to Anki-compatible formats, CSV, or PDF and keep studying wherever you already do.
How Students Use QuerySpark for Video
From a single recorded lecture to a full review playlist, turn the hours you spend watching into knowledge that sticks.
Paste your professor's recorded lecture, generate a quiz
Class recordings and uploaded lectures are gold but easy to zone out on. Drop the YouTube link into QuerySpark and turn an hour of video into a quiz that proves whether you actually absorbed it.
Paste a tutorial or explainer, generate review notes
Learning from channels like CrashCourse, Khan Academy, or a cert instructor? Convert any explainer video into notes and review questions so the watching turns into real, testable knowledge.
Turn your saved playlist into a full practice set
Built up a playlist of review videos? Convert them into flashcards and quizzes, then drill the combined set with spaced repetition in the run-up to your exam.
Works With Any Video Type
If it has a transcript, QuerySpark can turn it into study material
What to Expect
Paste a one-hour lecture link. Get a quiz, flashcards, and a study guide in about a minute. Quality depends on the source -- a clear lecture with good captions produces sharper questions than a rambling video with messy auto-generated captions.
QuerySpark generates questions from what the video actually says, not from a pre-made bank. It needs a transcript to work, so videos with no captions available can't be processed.
This generates practice questions, not official course content. We recommend reviewing the generated questions -- checking the answer keys against the video is itself an effective way to learn.
