I saw this app when it first appeared on AppSumo and ignored it, as the name gave me the impression it only summarised YouTube videos.

It does that and so much more. It manages to consolidate most social media platforms, PDFs, notes, and other media into one workflow. What I really like is that it allows me to bring all my disparate sources of information into a single place.

While there are other apps that attempt to do the same thing, this one works best for me because it is the most intuitive and has a very low learning curve.
