Not only a summary but key findings from books I’ve read and didn’t even think about.

### 5/5 — Amazing new take on this complex problem space

*2023-04-24*

Though we all want read all the great books but it is obviously not possible. This app is helping me find great new books to read for my interests as well as giving me summaries of other great books out there while i look through. Great recommendations, summaries with amazing UX. Still new to the app and will soon add here more things which i like about the app.
