Blinkist is the best-known book-summary app: 9,000+ non-fiction titles condensed into 15-minute "Blinks" you can read or listen to, plus expert guides and an AI summarizer on the top tier. It is excellent at telling you what a book says.
MindShark is not a summary app. You pick a topic — not a book — and it generates a Deep Dive of ten Modules, each made of five-minute Bites that end in a quiz. The point is to know the material afterwards, not just to have heard it.

Blinkist wins if your goal is coverage: the commute-length audio summary of the book everyone is quoting this month. It is polished, the library is enormous, and nothing else does that job as well.
MindShark wins if your goal is retention of a subject rather than familiarity with a book. Summaries are read-and-forget by design; a Deep Dive is quiz-and-return by design. It also costs half as much. Plenty of people use both — Blinkist to find out what is worth learning, MindShark to learn it.
There is a free tier with one editor-picked summary per day. Full access is Premium, with a 7-day trial.
Roughly $99.99/yr for Premium, with app-store SKUs between about $80 and $120 depending on the offer. MindShark Premium is $49.99/yr.
No. Blinkist is a reading and listening app. MindShark quizzes you at the end of every Bite and brings back what you missed.
Not directly. You give MindShark a topic, and it builds a course on the topic rather than a summary of one book.
Blinkist has the bigger library and better audio; Headway is cheaper annually and adds streaks and spaced review. Neither builds a course on a topic you choose.
