Is there any tool for busy people that can summarize text, audio and video of content you are following?

Hello,

I am wondering if there is any AI tool that can summarize content for you, for example summarize emails you get from your email account, audio from the podcasts you follow or videos from YouTube channels you are subscribed to?

A tool for busy people who don't have time to consume everything, but still want to be kept up to date.

Thanks!
