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 ↗About SoBrief
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.

Pros & cons of SoBrief
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.
Pros
- Catalogue in the tens of thousands, far larger than curated rivals
- Same summary available as audio, PDF and EPUB
- Around 40 languages supported
- Native iOS and Android apps plus a home-screen widget
Cons
- Summaries are machine-generated, so accuracy varies by title
- Publisher and country are undisclosed
- The site refuses automated access, so pricing cannot be verified at source
Best for
- Readers who want a large catalogue over hand-edited summaries
- Commuters who want the same summary as audio and EPUB
- Non-English readers underserved by Blinkist
Not for
- Anyone who needs summaries they can cite or trust verbatim
- Readers who prefer editorially commissioned condensations
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.
