Eightify
What it is
Eightify uses AI to summarize YouTube videos and highlight key information. Its summaries include timestamps for jumping to particular topics and an overview of a video's top comments. The service also provides transcripts, a transcript generator, and transcript summarization. Users can tailor key insights by focus, format, length, and grouping, then share summaries as links or export them. Summaries and translations are available in more than 40 languages. The Chrome extension listing says Eightify handles YouTube videos up to 10 hours long and is powered by Claude and ChatGPT. Named use cases include podcasts, interviews, science and technology, business, investing, news, health, and personal growth videos. Eightify is available on Android, iOS, web, and as a browser extension. A free plan and free trial are offered, alongside Pro at $9.99 a month, billed monthly, or $59.99 a year, billed annually. It does not summarize webpages or accept file uploads. Eightify says it collects account, device, and usage details and applies security measures, while noting absolute protection cannot be guaranteed.
