Keepframe — YouTube Video Notes As You Watch, Tailored Summary & Transcript

Turn long videos into usable knowledge. Keepframe is a Chrome extension that turns YouTube videos into notes. It helps you decide whether a video is worth your time, understand it while it plays, and turn it into Study Notes, a summary and a timestamped transcript. BEFORE YOU WATCH Not every long video is worth your time. Open a video and run "Should you watch this?" Keepframe reads the description and a selection of comments and gives you two concise views: why the video may be worth your time, and why you may want to skip it. It also shows the points viewers raise, information about the channel, and any chapters available for the video. You can open the original comments and judge for yourself. The pre-watch check is separate from your video analyses and never uses one of them. WHILE YOU WATCH Live Frames — concept cards that appear beside the player and explain the ideas being discussed, close to the moment they come up. They are built around the part you are watching, not from the top of the video, so the context arrives while the explanation is still unfolding. Each Live Frame offers several layers: a quick explanation, the segment's fundamentals, the wider background, why the idea matters, and — where one fits — an illustrating image with its license and author. Dig Deeper opens any concept as a fresh search in the service you choose, without losing your place in the video. Press Keep on a frame worth returning to and it is saved in Kept Frames with your own note. When the point is on the screen rather than in the words — a diagram on a slide, a table, a formula on a blackboard — Grab lets you save the relevant part as a Snapshot in Kept Frames for your own notes and personal learning. Draw a box around it, or capture the full visible frame. Each Snapshot includes a clickable timestamp that takes you back to the source video, and can go into your documents. A video analysis starts only when you press Analyze this video — or, on Power, when you switch on Auto-analyze in Settings. NOTES, SUMMARIES AND TRANSCRIPT Whenever you want to keep or review the takeaways, Keepframe turns the same video into documents tailored to different needs — a Brief for a quick overview, Study Notes for revision, a Full Summary for the whole walkthrough — each with clickable timestamps that jump back to the exact moment. Tick "Include what you saved and your notes" to bring your Kept Frames, Snapshots and notes into them. One analysis gives you the transcript and, when your plan includes them, lets you generate all three documents for that video. Analyzing it again — in another output language, for example — uses another analysis. The notes you add and the text Keepframe generates are yours to use for your own learning. AND WHEN YOU COME BACK Open the panel and Keepframe shows your recent videos with their Live Frames still loaded. Reopening one costs no analysis. Anything you press Keep on is saved locally in Kept Frames, together with your notes and Snapshots.
