The shortlist
Summio
AI-native and open-input — point it at any book, video, article, or PDF and you get a structured editorial summary you can chat with.
Blinkist

Gamified reading with daily streaks and challenges; strong onboarding for new readers.
Shortform
Editor-written long-form guides with commentary — closer to an analytical book club than a summary app.
Common questions
What is the cheapest AI book summary app?
Summio is the cheapest of the apps in this list at $39.99/year (Premium) — Blinkist is $99.99, Headway $89.99, Shortform $197. Free options like 4 Minute Books exist but are blog posts, not apps.
Which app summarises the most books?
Summio has the widest reach because it is open-input — any book you can name or upload as a PDF. Curated apps like Blinkist or Shortform have several thousand pre-written summaries each.
Can these apps summarise YouTube videos and PDFs too?
Only Summio. Blinkist, Headway, Shortform and Mentorist are book-only catalogues. If you also want to summarise YouTube, articles, or PDFs from one app, Summio is the only option here.
