What Eightify is
Eightify uses AI to summarize YouTube videos and extract their key information. Summaries include timestamps for jumping to topics, an overview of top comments, and video transcripts; a transcript generator and transcript summarization are also provided. Users can shape 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 and is powered by Claude and ChatGPT. Listed use cases include podcasts, interviews, science and technology, business, investing, news, health, and personal growth. It runs on Android, iOS, the web, and as a browser extension. A free plan and free trial are available. Pro costs $9.99 a month billed monthly or $59.99 a year billed annually. Webpage summarization and file uploads are not available. Eightify says it collects names, email addresses, IP addresses, device details, and usage data.
