The Chrome extension listing says it handles videos up to 10 hours and is powered by Claude and ChatGPT. Eightify names podcasts, interviews, science and technology, business, investing, news, health, and personal growth as possible subjects. It is available on Android, iOS, web, and as a browser extension. A free plan and free trial are available. Eightify Pro costs $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 contact, device, and usage data and applies security measures, while noting that absolute protection cannot be guaranteed.
