What is this tool?
The strongest case is triage: deciding whether a long talk, podcast or lecture is worth your time, and if it is, landing on the three minutes that matter. Timestamps are what make that work — the summary is a way into the video rather than a replacement for it. Plan for the cost, though: it is distributed free with in-app purchases, so there is no plan to price before you install and the upgrade meets you inside the product.

Every key point Eightify produces carries a timestamp back into the video, and that single design choice sets the whole workflow: you skim the points, decide whether the video is worth an hour, and if it is, you start at minute thirty-four instead of minute zero. It is a filter on a watchlist rather than a substitute for watching: summaries that do not link back leave you trusting the summariser, and these let you check. The ten-hour ceiling matters for the same reason — the videos where this pays off most are the ones nobody has time to sample by scrubbing.
The product is published by Rational Expressions Inc. and distributed free with in-app purchases, and the Chrome listing carries 200,000 users, a 4.0 rating across 859 ratings and a last update in November 2025 — a real user base and a maintained extension. What none of that gives you is a figure. The upgrade sits behind the install rather than in front of it, so the running cost of a research habit built on this is something you meet later rather than something you compare now.
On data, the developer's declaration on the store listing is narrow but specific: material is neither sold on nor used for anything outside what the extension does. That covers the two things most people worry about. It leaves the rest open — how long transcripts are kept, who processes them, and which model writes the summary. For public YouTube content that is a small question. For a workflow that ends up pointed at internal recordings, it is the one to settle first.
Is this right for you?
Quick fit check against how you actually work.
Choose this if
- You watch long-form YouTube — conference talks, podcasts, lectures — and need to decide fast which ones deserve the full hour
- You want to jump to the part of a video that matters rather than read a summary instead of watching
- You follow video content in a language other than your own, or work across several
- You start on a phone and finish at a desk, since one account covers Chrome, iOS and Android
- You want the video's top comments alongside the summary as a check on what it claims
Consider alternatives if
- Your sources are not YouTube: this is built around YouTube videos, not arbitrary media files or other platforms
- You need to compare a monthly cost against alternatives before installing anything, since the price only appears once you are inside the app
- You expect to lean on free use for more than a trial — viewers in the community repeatedly describe running out of free summaries quickly and going looking for alternatives in the same breath
- You need a documented data-handling position for work material: the developer's declaration covers sale and transfer, and says nothing about retention, sub-processors or which model writes the summary
What people say
Aggregate community sentiment, summarized — not native reviews.
Mixed signals
Viewers who describe the summaries themselves are positive about the quality and the time saved. The recurring friction is elsewhere: on one Spanish-language walkthrough several people reported reaching the end of free use after a handful of summaries, and two of them asked the creator to cover free alternatives instead. How large the free allowance actually is remains the vendor's to state.
Key features
What you can actually do with this tool.
Key points that link back to the video
Each point carries a timestamp that jumps to the moment it came from. Paste a transcript into a chatbot and you get a summary you must take on trust; here a claim can be checked against the source in one click, which matters when the summary is the basis for a decision.
About five seconds per video
The vendor puts the turnaround at roughly five seconds. At that speed summarising becomes a triage habit you apply to everything in the queue rather than a step you decide to spend time on.
Videos up to ten hours
The ceiling is high enough for full conference recordings, multi-hour podcasts and streamed lectures — the formats where reading a summary first saves the most, and where many summarisers stop working.
Transcript and top comments in the same panel
It returns an improved transcript and a digest of the video's most-upvoted comments. The comments are often where a video's claims get corrected, so having them next to the summary is a genuine check rather than an extra.
Forty-plus languages, one account across three platforms
Summaries and interface run in more than forty languages, and a single account covers Chrome, iOS and Android — so a video found on a phone can be read properly later at a desk.
Frequently asked
Common questions about this tool, answered.
What does it cost?
The extension installs free and charges through in-app purchases, so the upgrade price appears inside the product rather than on a page you can read before installing. No plan, allowance or monthly figure is published on a surface that serves a reader. If a predictable number matters — for a team, or for anything you intend to build a habit on — get it from the app or the vendor before committing.
Does it replace watching the video?
It is not built to. The summary's points are links into the timeline, which is a design for deciding what to watch and where to start rather than for skipping the video altogether. Used that way on a queue of hour-long talks it saves a great deal; used as a substitute for a video whose detail actually matters, you are trusting a five-second reading of ten hours of speech.
Can I use it on my phone?
Yes. The same subscription runs on Chrome, iOS and Android under one login, so a video saved on a phone can be summarised there and picked up later at a desk.
