Paste a YouTube link and get a clear, accurate summary of the key points — built from the actual transcript, not guessed. Then go deeper: full notes, flashcards, quizzes, or a podcast. One link, everything you need.
Get the gist of a long video in seconds — or turn it into a full study set. Both. Your call.
Paste a YouTube URL and get a clean summary of the main points in under a minute. No scrubbing, no rewatching, no guessing what matters.
The summary is built from what the speaker actually said — Cramberry reads the real transcript, so key points aren't invented or paraphrased beyond recognition.
Read the summary first. If the content matches what you need, go deeper. If it doesn't, move on. Stop losing hours to videos that don't deliver.
Main claims, supporting evidence, and conclusions — structured and readable, not just a wall of bullet points. The AI organizes by theme, not by timestamp.
One click from summary to full study notes, flashcards, a multiple-choice quiz, or an AI podcast. Everything lives in one StudySet — never scattered.
Have a recorded lecture, a podcast, or any audio file? Upload it directly and Cramberry will transcribe, then summarize it just the same.
Paste a link. Get the key points. Go as deep as you want.
Cramberry fetches the full video transcript, reads it end to end, and produces a clean, accurate summary of the main arguments, key takeaways, and important details — in seconds. No signup needed to try your first video.
A summary tells you what the video covers. Full study notes tell you how — every concept explained, every example captured, every definition included. One click turns the same transcript into comprehensive, organized notes ready to study from.
Reading a summary is passive. Actually retaining the material requires testing yourself. Cramberry converts the same video into flashcards, multiple-choice questions, short-answer quizzes, and practice tests — so you move from knowing what it said to knowing it.
After summarizing, you can ask the AI Tutor anything about the video — clarify a point the speaker made, get a deeper explanation of a concept, or explore a related idea. The tutor is context-aware of your specific video, not just the topic in general.

From URL to summary in under a minute.
Copy a YouTube URL — a lecture, a talk, a tutorial, anything educational — and paste it into Cramberry. Or upload an audio recording to transcribe and summarize instead.
Cramberry reads the full transcript and produces a clean, accurate summary of the key points. From there, add full notes, flashcards, a quiz, or a podcast in one more click.
Read the summary, explore full notes, test yourself with quizzes, or ask the AI Tutor anything about the video — all in a single StudySet, all in one place.
A good summary tells you what a video covers. But knowing what was said and actually retaining it are two different things. Active recall — testing yourself on the material rather than just reviewing it — consistently produces stronger, longer-lasting memory than passive re-reading or rewatching.
That's why Cramberry doesn't stop at summaries. After you get the gist, you can instantly generate flashcards, quizzes, and practice tests from the same video content. The testing effect is one of the most replicated findings in learning science: the act of retrieving information is itself what makes it stick.
Based on established principles of active recall, retrieval practice, and the testing effect — widely supported in cognitive and educational psychology research.
YouTube videos are the main input here — but Cramberry handles plenty more.
