I use this every day for research. Instead of watching 2-hour lectures, I get the key points in 30 seconds. Absolute game-changer for my PhD workflow.
The custom prompt feature is brilliant. I set it to extract action items and timestamps — now every video I watch turns into an actionable note automatically.
Been using it with Claude API. The summaries are incredibly thoughtful. Worth every penny of the Pro plan — honestly surprised it's only $11.99/year.
