Keepframe
Keepframe VS Glasp: A library of what you watched, or learning while you watch?
Glasp is a social web highlighter with a library: you highlight articles, PDFs and videos, generate summaries, and organise everything for later. Keepframe stays with the video you are watching and turns that session into material you keep.
Free plan: 10 analyses per month. No account required.

Which one fits you
An honest split
Sometimes the right answer is not us. Here is where each tool genuinely wins.
Choose Keepframe if your learning is video
- You want the explanation while the idea is on screen. Concept cards surface beside the player as the video plays.
- You want the session to end with study materials. On paid plans the same analysis produces a Brief, question-and-answer Study Notes and a Full Summary you can export.
- You want a predictable allowance. An analysis is an analysis; generating the Brief, Study Notes or Full Summary does not consume another one.
Choose Glasp if you collect across the web
- You highlight more than you watch. Glasp describes itself as a social web highlighter for websites, PDFs and YouTube videos.
- You want a permanent, shareable library. What you save is organised in one place and can be shared and explored with others.
- You want to pick the AI model. Glasp states its summaries can run on ChatGPT, Claude, Mistral AI or Gemini, with a custom prompt and length.
More reasons for each
Keepframe
- Outputs are generated in the language you select, independently of the language spoken in the video, provided a usable transcript exists.
- Nothing is uploaded or filed anywhere else — the work happens beside the player.
- Every concept card carries a Dig Deeper link if you want to go past the summary.
Glasp
- Works beyond Chrome — the vendor lists extensions for Safari, Edge and Firefox, plus iOS and Android apps.
- Highlights and notes from Kindle eBooks can be synced into the same library.
- Export to note apps: the vendor lists Notion, Obsidian and Roam Research, in Markdown, HTML, CSV and JSON.
- Basic YouTube summaries are available on the free plan, within a daily limit stated by the vendor.
Two workflows
How each one works

- Summarise it with the AI model you choose
- Save highlights and notes to your library
- Review, organise and share them afterwards
Keepframe

- Learn and dig deeper during playback
- Generate, review or export materials

What is actually different
Both tools will leave you with something after a YouTube video. The real difference is when the learning happens, and where your material ends up.
Glasp is built for collecting. You highlight what matters — in articles, PDFs and videos — and everything lands in a library you can organise, revisit and share. Its YouTube summariser produces a summary on request, with the AI model and prompt you choose. If your reading and watching feed a long-term collection, that library is the point, and it is something Keepframe deliberately does not attempt.
Keepframe is narrow on purpose. It lives inside YouTube. While a video plays, a concept card can appear beside the player explaining the idea currently being discussed — what it is, the fundamentals behind it, why it matters — so the explanation arrives while the idea is still on screen. The timestamped transcript is available on the free plan; on paid plans the same session also produces a Brief, question-and-answer Study Notes and a section-by-section Full Summary.
There is also a difference in what you keep. Glasp keeps a library: highlights, notes and summaries, stored together and shareable with others. Keepframe keeps documents: the Brief, Study Notes and Full Summary can be exported as PDF or Word files and live wherever your files live. Which suits you depends on whether you are building a collection or studying the video in front of you.

Frequently asked
Quick answers
Do Keepframe and Glasp do the same thing?
Less than it appears. Glasp is a highlighter with a library: it collects what you save and summarise, so you can organise and share it after you watch. Keepframe is a learning layer that works while the video plays and ends the session with study materials. They overlap on YouTube summaries, and differ on almost everything around them.
Can Keepframe summarise a PDF or an article?
No — not as a source. Keepframe reads YouTube videos only. It does export the materials it produces as a PDF or a Word document, but it cannot take a PDF you bring to it. If you highlight and collect mixed sources in one place, Glasp is the better fit.
How is usage counted on each?
Keepframe counts analyses — one per video — and the Brief, Study Notes and Full Summary generated from that video do not consume another. Glasp's free plan caps basic YouTube summaries per day; its paid plans list unlimited basic summaries with monthly caps on advanced summaries.
More questions
Which one is better for a video in another language?
Keepframe generates its output in the language you select, whatever language is spoken in the video, as long as a usable transcript exists. Glasp states its summaries and transcripts support multiple languages, so both are viable — the difference is whether the material is built for a long-term collection or for the session you are in.
Does Keepframe keep a library of my past videos?
Not in the way Glasp does. Keepframe's materials leave as documents — PDF or Word files — rather than living in a social library. If a permanent, shareable collection is the goal, that is Glasp's home ground.
