For students & study groups

A long lecture. Notes you can study.

Keepframe works beside the YouTube player. Live Frames arrive as you watch, and the Study Notes they become export as PDF or Word — with timestamps that take you back to the moment.

For creators

Research a long video before you script.

Pull the argument out of a two-hour talk: concept cards as it plays, a transcript where every line jumps back to its minute, and Grab to keep a diagram or a frame with its timestamp.

  • Grab any diagram, table or visible frame — it lands in Kept Frames as a Snapshot, with the minute it came from.
  • A timestamped transcript you can export as plain text, subtitles (.vtt) or Word.
  • Brief for the overview, Full Summary when you need the whole picture.

Come back to the exact passage.

A transcript that carries the minute each line came from, concept cards beside the video, and Dig Deeper to open any concept as a fresh search in the service you choose — while the video keeps playing.

  • Every transcript line jumps back to its minute in the video.
  • Dig Deeper opens a highlighted term, or the whole subject of the card, in its own tab.
  • Read the output in your own language — 95 are available; pick yours before you analyze.

Your YouTube learning companion

Turn long videos into usable knowledge.

For anyone curious, whatever the subject: understand faster, remember more and export study materials tailored to each video. Keepframe is a Chrome extension that adds Live Frames — concept cards beside the YouTube video, close to the moment each idea is explained. A concise Brief, Study Notes, a detailed Full Summary or the full Transcript: each has its own job, and clickable timestamps take you back to the moment you need.

Before you watch

Before you invest your time.

Not every long video is worth your hour. 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.

  • Two concise views: why the video may be worth your time, and why you may want to skip it.
  • The channel behind the video and its chapters, before you commit.
  • This check never uses one of your video analyses.

Before a single analysis is spent — the chapters, the description and the two views, on a twelve-minute documentary.
The problem

The best knowledge is locked inside long videos.

Lectures, podcasts and deep-dives hold real insight — but watched passively, the key concepts fade fast.

Everyone hits the same friction: great content, no structure to study from.

  • Key ideas slip by as you watch — and rewatching to find one wastes time you don't have.
  • A one-line summary is too thin to study or revise from.
  • Notes end up scattered across apps — or never written.

Live Frames as you watch, the Study Notes they become — and the file you take with you. One video, one panel, three steps.
The solution

From passive watching to active learning.

Keepframe adds a clean learning panel right next to the YouTube player. Live Frames arrive as you watch — then, whenever you want, open the transcript, Brief, Study Notes or Full Summary and export them.

  • Live Frames follow the video moment as it plays.
  • Press Keep to save the ones that matter — and add your own note.
  • One panel holds the transcript and all three documents.
  • Export clean study documents you actually keep.
Features

Made for learning, not just for skimming.

Not a summary bolted on afterwards — a full learning workflow, where you already watch.

Before you invest your time

Is this hour worth it? Keepframe reads the description and a selection of comments and tells you what makes the video worth your time, what might make you skip it, and who is behind the channel. Costs no analysis.

Live Frames, kept for later

Key ideas appear beside the video, at the moment they are explained. Press Keep on the ones worth returning to, add your own note, and find them in the Kept tab. Reopen a recent video and its cards are still there — no analysis spent.

Dig deeper, in your language

Any highlighted term — or the whole subject of the card — opens as a fresh search in its own tab, in the service you choose, while the video keeps playing. And the language of the video is not the language you have to read in: pick yours before you analyze, from 95.

Grab what is on screen

A diagram on a slide, a table, a formula on a blackboard — draw a box around it and it is saved as a Snapshot in Kept Frames, with a clickable timestamp back to the moment it came from.

Three depths, one video

Brief for the executive overview, Study Notes for revision and recall, Full Summary when you need the whole picture — plus a clean transcript where every line jumps back to its minute.

Take it with you

Export your documents, Kept Frames and transcript as Word or PDF. Links back to the video stay clickable, so the file still points at the source.

How it works

Getting started, in five steps.

Add Keepframe to Chrome

Two clicks on desktop Chrome. No account, no sign-up.

Open a video and pick your output language

Any YouTube video that has captions. Choose the language before you analyze, not after.

Press Analyze this video

Nothing runs until you do, unless you are on Power and switch on Auto-analyze in Settings. “Should you watch this?” is a separate check and costs no analysis.

Keep, generate, export

Keep the frames worth returning to, build your documents, take them with you.

When you come back

Open the main Keepframe panel on YouTube and it 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.

What a Live Frame holds

Five sections you can fold away — VISUAL, IN BRIEF, FUNDAMENTALS, WIDER BACKGROUND and WHY IT MATTERS — with the key phrases highlighted in the text and Dig Deeper at the bottom. One card, several depths: open only the part you need.

See it in action

Every part of it, on a real video.

Real lectures and talks, captured from the panel as it runs. Each tile is a close-up of the panel — open one to see the whole screen it came from.

Privacy

You're in control of what gets analyzed.

You choose the video

An analysis starts when you press Analyze this video, or, on Power, when you switch on Auto-analyze in Settings. Nothing else is analyzed on its own, and you decide which video to turn into learning materials.

Private by default

No Keepframe account required. You do not create an account or sign up, and there is no personal profile; your usage is tied to a pseudonymous installation identifier. Paid subscriptions are handled securely by Stripe, which receives the email address you give it at checkout. We never sell your data.

Used only to build your materials

For the feature you choose, the extension uses the video's transcript and details — including the description and a selection of comments for “Should you watch this?” — to produce what you asked for. A public video’s transcript may also be kept for a limited time in a shared cache. See the full Privacy Policy.

FAQ

Questions, answered.

Can I check whether a video is worth watching before I commit an hour?

Yes. Open the video and run “Should you watch this?” Keepframe reads the description and a selection of comments and shows you why the video may be worth your time and why you may want to skip it. It never uses one of your video analyses. On Free it is available during your first 7 days; on Pro and Power it is always available.

Does it work on all YouTube videos?

It works on YouTube videos that have captions available — either uploaded by the creator or auto-generated by YouTube. If a video has no captions at all, Keepframe can't build Live Frames or documents for it.

Do I need YouTube Premium?

No. Keepframe works with standard YouTube and does not require YouTube Premium.

Does it work on desktop Chrome?

Yes. It's a desktop Chrome extension and runs in a sidebar next to the YouTube player. It's built for the desktop browsing experience.

What happens if a video has no captions?

Live Frames and study documents are generated from the transcript, so a video with no captions can't be analyzed. You'll see a clear message rather than an empty panel.

What counts as one analysis?

One analysis covers that video’s transcript and the Brief, Study Notes and Full Summary you generate from it — those are not separate analyses. Analyzing the same video again, for example in another output language, uses another analysis.

What is the difference between Brief, Study Notes and Full Summary?

The Brief is a short executive overview — core thesis and key takeaways. Study Notes are structured, organized notes built for revision. The Full Summary is a detailed written walkthrough of the video, section by section.

Where do the documents come from?

Every document is written from that video’s captions — the same transcript you can open in the Transcript tab. Nothing else is consulted: no other sources, no fact-checking against the web. That is why each exported document carries the line “Based on the video’s captions — check key facts against the video.” Treat it as a faithful write-up of what was said, not as a verified account of what is true.

How long do the documents take?

The transcript opens once you analyze the video — it arrives together with your Live Frames. The Brief, Study Notes and Full Summary are generated when you ask for them; how long that takes depends on the length of the video. They are not kept after a page reload or once you move to another video, so export the ones you want to keep.

Is there a free plan?

Yes. Free gives you a monthly allowance of video analyses, Live Frames on every video you analyze, the timestamped transcript, Kept Frames with your own notes, and Dig Deeper. For your first 7 days you can also create and export the Brief, Study Notes, Full Summary and your Kept Frames — within your monthly allowance, with no card required.

What can I do on Free after the first 7 days?

Live Frames, the transcript, Kept Frames and Dig Deeper stay available on Free, and you can still copy available text to the clipboard. Creating new documents and exporting files require Pro or Power.

Can I export the result?

Yes. Documents export as Word (.doc) or PDF, your Kept Frames as Word, PDF or a ZIP of their Snapshots, and the transcript as plain text, subtitles (.vtt) or Word. Export is included in Pro and Power, and in your first 7 days on Free. The notes you add and the text generated for you are yours to use for your own learning. Snapshots are intended for personal notes and learning. Rights in the source video and on-screen material remain with their respective rights holders.

How much of a video does each plan cover?

Live Frames are built around where you are watching, not from the top of the video, so the coverage lands on the parts you actually reach. Free covers the area around the part you are watching. Pro reaches further ahead, for talks, lectures and longer videos. Power keeps building across the whole video, including multi-hour material — on very long material Free and Pro eventually run out of new Live Frames for that video, and Power does not.

How do languages work?

You choose the language your Live Frames and documents come out in — 95 languages are available. The transcript stays in the language of the video, and the extension's own interface is in English. Pick your output language before you run the analysis: changing it afterwards means analyzing the video again.

How does privacy work?

You choose which videos to analyze. For the feature you choose, the extension uses the video's transcript and details — including the description and a selection of comments for “Should you watch this?” — to produce what you asked for; a public video’s transcript may also be kept for a limited time in a shared cache. Usage is tied to a pseudonymous installation identifier and we don't sell your data. Full details are in the Privacy Policy.

Can I cancel paid plans?

Yes. Paid plans are billed monthly or annually and you can manage or cancel your subscription at any time. Need help? Email support@keepframe.one.
