Library of AI-written book summaries in audio, PDF and EPUB, with a home-screen quote widget.
SoBrief is a book-summary library rather than a summarizer you feed your own text into. It keeps a catalogue of tens of thousands of fiction and non-fiction titles condensed to roughly a ten-minute read, offered as audio, PDF and EPUB in about 40 languages, with mobile apps on iOS and Android. A home-screen and lock-screen widget rotates key takeaways and quotes through the day, which is the feature regulars mention most. The site blocks automated fetches, so the figures recorded here come from its app store listing and third-party trackers rather than the vendor page: a limited free tier, a Pro subscription, and a one-time lifetime option. No company or country is disclosed.
Pro is reported at $9.99/month or $44.99/year with a lifetime purchase near $79.99 and a 30-day refund window. None of that was legible at source, because sobrief.com answers crawlers with HTTP 403.
Use tool ↗SoBrief competes with Blinkist on catalogue size and price rather than on editorial quality, since the summaries are machine-written rather than commissioned. The multi-format export and 40-language coverage are the real differences, and the lifetime purchase makes it cheap over a couple of years. Nobody is named as the publisher, which matters when the whole product is derivative text about other people's books.
Watch out: Machine-written summaries of copyrighted books with no named publisher is a licensing posture worth thinking about before you build a habit on it.
