Which one is for you
Pick Eightify if
- 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
Look elsewhere if
- 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
Pick Liner if
- Fits if you want every line of an AI answer tied to a source you can open
- Works for students drafting a literature review or hunting for citations, on a desktop
Look elsewhere if
- Skip it if ads in your answers would bother you and you don't plan to pay
- Tight if you lean on the agents, since Pro's 1,000 credits go at 30 to 80 a request
- Not for you if you do your research on a phone, as Liner Scholar and Liner Write are desktop only
- Watch out: Liner doesn't offer refunds, so cancel before the renewal date
- Too light for agent work on the free plan, which allows 1 upload a day and lists 0 agent credits
How we grade them
| 2.4GPAEightifyFair | 2.6GPALinerGood | |
|---|---|---|
| Value for money | CNo 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. | CPro is $14.99 a month billed annually, or $17.99 monthly, which sits above this category's middle of about $12. It does cover all three products and drop the ads. But the agents run on credits: Pro gets 1,000 and one Deep Research request spends 40, and unlimited uploads mean Max at $29.99. |
| Free plan and trial | CA 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. | CAdvanced Search is unlimited, but the rest is thin: ads in the answers, 1 file upload a day, and the plan table lists 0 agent credits, though the FAQ says there are some. So Deep Research and the Scholar agents, the reason you'd come here, are shut. Caps you'll hit. |
| Features | CVideo 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. | BIt covers the whole job: a citation on every line of an answer, Deep Research reports, Scholar agents for literature reviews, citation finding and peer review across 480 million papers, and Liner Write for the drafting. What it hasn't got is a trick its rivals lack. |
| Ease of use | BNo store rating on record. Install the extension and press a button on a video. | C4.4 on the App Store from 1,371 ratings, which is middling rather than good: our higher band starts at 4.5. Asking a question is simple enough, but credits are the thing to learn, since each agent request costs between 30 and 80 of them. |
| Platforms and integrations | BChrome 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. | AWeb, Mac, Windows, iPhone, Android and extensions for Chrome and Edge, plus a search API and MCP servers that hand its scholar search to other AI agents. The catch is that Liner Scholar and Liner Write are desktop only. |
| Best for | summaries of YouTube videos | AI answers with a source on every line |

More comparisons
How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
