SoBrief
Read any book's key ideas in about 10 minutes
Overview
SoBrief is a book summary app built to get you the core ideas of a book in about 10 minutes instead of the several hours a full read takes. The library is large, tens of thousands of titles across business, psychology, self-help and more, and reading the text summaries is free. The audio version, which a lot of users prefer for commutes or workouts, sits behind the paid tier.
This is a tool for people who want to sample a lot of books quickly, not for people who want the actual depth and nuance of the source material. A 10-minute summary of a 300-page book leaves a lot out by definition, and some users have flagged paywalls that show up sooner than expected on features they thought were free. Treat it as a way to decide which books are worth your full attention, not a substitute for reading them.
