Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.4
GPA, above 19 of the 49 other AI research tools we grade
Eightify is a Chrome extension, with iOS and Android apps, that summarizes YouTube videos into key insights with timestamps. It can show an overview of top comments, generate transcripts, and work in over 40 languages. Its Chrome Web Store listing says it handles videos up to 10 hours long and is powered by Claude and ChatGPT.
To get you started, here are 8 things to know about Eightify, taken from its own pages and our grades.

The report card
Best for summaries of YouTube videos
Eightify is a Chrome extension and phone app that summarizes YouTube videos into key points. But it only works on YouTube, its own site blocked our reader so no price could be read, and the Chrome Web Store page gives a 7-day trial and in-app purchases with no figure.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | C | No price could be read: the site answered every request with a Cloudflare block, and the store page names in-app purchases without a figure. With nothing to compare, it sits at C. |
| Free plan and trial | C | A 7-day free trial of the Chrome extension, per its store listing. The listing does not say if a card is needed, and there's no free plan on record. |
| Features | C | Video summaries, customizable insights, transcripts and a top-comments overview. A focused tool that does one job on one site, and the listing doesn't describe summarizing PDFs or web pages. |
| Ease of use | B | No store rating on record. Install the extension and press a button on a video. |
| Platforms and integrations | B | Chrome extension, plus iOS and Android under one account per the listing, though the app store pages weren't read. Only YouTube is listed to connect. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who Eightify is for
- Fits if you want the gist of a long YouTube video before you commit to it
- Works for someone who watches talks and tutorials in Chrome
Who it is not for
- Skip it if you want to summarize PDFs or web pages, since only YouTube videos are described
- Not for you if you want to see a price first, as none could be read
- Watch out: the free trial is 7 days and the listing doesn't say what happens after
- Watch out: the vendor's own site blocked our reader, so this card rests on a store listing
Good to know
Good for
- People who watch long talks, podcasts and interviews on YouTube and want the gist first
- Researchers screening videos before committing time
- Users who want one account across Chrome, iOS and Android
Worth knowing
- Eightify's own site answered every request with a Cloudflare block, so no prices could be read and none are recorded.
- The Chrome Web Store listing describes a 7-day free trial and in-app purchases but states no price.
- It works on YouTube videos; the listing does not describe summarizing PDFs or web pages.
- The listing mentions iOS and Android use under one account, but the app store pages were not read.
Part 02 · Pricing
What it costs
Every plan, the free plan, ways to pay less and how prices have moved
Eightify's current pricing could not be confirmed from its own site.
No price could be read: the site answered every request with a Cloudflare block, and the store page names in-app purchases without a figure.
We could not confirm Eightify’s current prices from its own site, so this guide lists no plans. eightify.app has them.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
To replace Eightify you would be making an AI model, which you can rent by the request but not make. That is not a weekend's work, with an AI app builder or without one.
What you could not
- An AI model, which you can rent by the request but not make.
- A library of papers and sources to search.
- Speech turned into text you can trust.
- A real app for iOS and Android. Something home-made would be a web page.
What this rests on. Eightify’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
