Keepframe
Keepframe VS Eightify: Summary first, or learning while you watch?
Eightify helps you understand a video quickly. Keepframe helps you learn from it as it plays.
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.
When Keepframe is the better choice
- Watch closely. Designed to support the viewing session rather than replace it.
- Learn and dig deeper. Concept cards appear during playback, and Dig Deeper opens any concept in the source you choose.
- Keep structured materials. Paid plans add a Brief, Study Notes and a Full Summary, with export.
When Eightify is the better choice
- Triage quickly. For "is this worth my time", a fast summary is the more direct choice.
- Mobile access. iOS and Android with one account across devices. Keepframe is Chrome only.
- Videos without usable YouTube captions. Eightify says it generates transcripts even without them.
More reasons for each
Keepframe
- You regularly learn across languages. Outputs in your selected language when a usable transcript is available.
- You want to start without an account. The free experience works right after installing — no sign-up, no email address.
Eightify
- You want the audience view. Eightify summarizes the comment section; Keepframe does not.
- You value a long track record. Years in market and an extensive review history. Keepframe is newer.

What is actually different
The feature lists overlap. The meaningful difference is when each tool does its work, and how the resulting material is structured for later use.
Eightify leaves you with a concise summary, key insights and a transcript designed for rapid review and navigation. Keepframe's paid workflow adds a Brief, question-and-answer Study Notes and a section-by-section Full Summary, designed as materials to retain or revise from after the session.
Eightify is optimized for compression. You open a video, ask for a summary, and you receive key ideas, timestamped navigation and a transcript. For a two-hour interview you were not sure about, that is exactly the right shape of tool — it is designed to do this more directly than a learning-oriented workflow.
Keepframe assumes the decision to watch has already been made. As the video plays, it can surface a concept card beside the player explaining an idea currently under discussion: what it is, the fundamentals behind it, why it matters. You are not leaving the video to read about it afterward; the explanation arrives while the idea is still on screen.
The timestamped transcript is available in the free experience. On paid plans, the same session can also produce a Brief, Study Notes and a Full Summary, with export enabled.
The third difference matters most when the video is not in your first language. Keepframe generates its outputs directly in the language you select in the panel — or leaves it to automatic detection — independently of the video's language, provided a usable transcript exists. You can watch a lecture in English or Mandarin and get your study notes in Polish, Spanish or Portuguese. Eightify also supports over 40 languages for summarization and translation, so this is a difference of degree and workflow rather than an exclusive capability.
