Install the extension, open any YouTube video and the summarizer returns the key ideas directly alongside the player. Because the insights are timestamped, you can jump straight to the topic that interests you instead of scrubbing through the timeline. The same summaries are available on the web and through the iOS and Android apps, so a saved video can be caught up with on mobile. Beyond bullet points, Eightify generates transcriptions that often beat YouTube's own subtitles, lets you skim the top comments to gauge whether an audience found the video useful, and produces summaries and translations in more than 40 languages. One-click sharing turns a finished summary into a readable article you can send to a colleague or classmate, which is why it is popular with students, educators, journalists, analysts and busy professionals who need the gist of a lecture, podcast or hearing. The product is freemium: there is a free entry point and paid subscriptions for heavier use, and it has been used by hundreds of thousands of people worldwide. It works on virtually any YouTube video, including long committee hearings, multi-hour interviews and your own uploads. **Pricing & Plans:** Freemium, with a free tier to try the summarizer and paid subscription options for regular, heavy use. Exact prices depend on the current plan menu shown at checkout. - **Timestamped key insights:** Get the main ideas of a video with timestamps so you can jump directly to the topic you care about. - **High-quality transcripts:** Access transcriptions that users report are cleaner and more accurate than YouTube's built-in subtitles. - **Top comment overview:** Skim a digest of the top comments to see whether viewers like you found the video useful. - **40+ language support:** Generate summaries and translations in more than 40 languages for global content. - **Shareable summary articles:** Turn a finished summary into a readable article and share it in one click with colleagues or classmates. **Strengths:** Works inline on YouTube as an extension plus web and mobile apps; Timestamped summaries let you navigate straight to the relevant section; Transcript quality and top-comment digest add context beyond bullet points; Summaries and translations in 40+ languages **Limitations:** The most intensive usage sits behind a paid subscription; Requires an extra extension install for the smoothest YouTube experience; Summary quality still varies with audio clarity and video type [Profile (Markdown)](https://openaitools.app/tool/eightify.md) ## Knowt Knowt is a study platform built around flashcards and AI study tools, and it markets itself as the leading free Quizlet alternative.
