SumAI is an iPhone and iPad app that summarizes YouTube videos, web articles and PDFs and adds study tools. If you watch YouTube at a desk, Eightify fits naturally. If you live on your phone, or need more than YouTube, look at SumAI. _Disclosure: SumAI is our app. Facts about Eightify come from its own public pages and store listings, last checked on 2026-11-12._ ## SumAI and Eightify side by side | | SumAI | Eightify | | --- | --- | --- | | Where it runs | iPhone and iPad | Chrome and Safari extensions, iPhone and Android apps | | Sources | YouTube videos, Shorts and live streams; web articles; PDFs | YouTube videos | | Summary | Five styles: TL;DR, Standard, Detailed, Study Guide, Chapters | TL;DR and key insights, with options for focus, format and length | | Timestamps | Chapters and key moments; tap a time to jump into the video | Timestamped navigation | | Transcript | Full transcript with timestamps, ready to copy | Yes | | Chat with the video | Ask AI, with tappable timestamps | Not listed on Eightify's site | | Mind map, quiz, flashcards | All three, generated with every summary | Not listed on Eightify's site | | Comments | Not included | Overview of a video's top comments | | Languages | Summaries in more than 60 languages | Summaries and translation in 40+ languages | | Export | PDF or Markdown, plus share and copy | Share a summary as a link | | Price (US App Store) | Premium $2.99 a week or $29.99 a year | Pro $9.99 a month or $59.99 a year | | Latest iPhone app update | October 2026 (version 2.0) | April 2025, according to its App Store listing | ## Choose SumAI if - You summarize on your **iPhone or iPad** rather than in a desktop browser. - You also want to summarize **PDFs and web articles**. - You want to **ask questions** about a video and get timestamped answers. - You want a **mind map, quiz and flashcards** for studying. - You want a summary in one of **60+ languages**. ## Choose Eightify if - You watch YouTube on a **computer** and want the summary beside the video. - You need an **Android** app. - You find the **comment overview** useful for judging a video. - You only ever summarize **YouTube**, and want a tool focused on that. ## Built for different screens Eightify grew up in the browser. Its Chrome extension, which its store listing says has 200,000 users, puts a summary next to the video you are watching on YouTube. For people who do their watching on a laptop, that placement is hard to beat: no copying links, no switching apps. SumAI is built for the phone. You paste a link or share from the YouTube app, and everything happens in a native iPhone and iPad app. Both approaches are sensible. The first question to ask is simply where you watch. ## What Eightify does well - **In-page summaries on desktop.** The summary appears where you already are. - **Android support.** SumAI has no Android app. - **Comment overview.** Eightify summarizes a video's top comments, which can tell you quickly whether viewers found it accurate or useful. SumAI does not do this. - **Focus.** It does one thing: YouTube. ## What SumAI adds - **More than YouTube.** Web articles and PDFs go into the same library as videos. - **Ask AI.** A chat with the video, with timestamps in the answers. Eightify's site does not list a chat feature. - **Study tools.** A mind map, a quiz and flashcards for every summary. Eightify's site does not list these. - **Five summary styles**, including a Study Guide and a Chapters style for long videos. - **Export** as PDF or Markdown. ## A note on the iPhone apps Both products have iPhone apps. As of 12 November 2026, the App Store shows Eightify's iPhone app as last updated on 3 April 2025, while its Chrome extension was updated in November 2026. An app that has not changed recently can still work well, so treat this as one data point rather than a verdict. SumAI's current version, 2.0, was released on 26 October 2026. ## Price Eightify has no public pricing page on its website; plans appear after sign-in. The figures in the table are the in-app purchase prices shown in the US App Store, and its Chrome listing describes a 7-day free trial. We could not confirm what, if anything, Eightify offers free after the trial. SumAI is free to download with an optional Premium subscription. ## What they have in common Both work from a video's captions, so neither can summarize a video that has none. And both produce AI summaries, which are a fast way in and worth checking against the video when a detail matters. ## Frequently asked questions ### What is the difference between SumAI and Eightify?
