Summio — AI Summaries of Books, YouTube, Articles & PDFs

Overview

A reading companion for iPhone. AI summaries of books, YouTube videos, articles and PDFs — plus a chat with every book you finish. 27 languages.

The reading app for the people who still read— and for those who want to start again. Trustworthy summaries. A library you carry. A conversation with every book.

And the book is still there, waiting. Summio summarises when you need the gist, remembers what you cared about, and quietly hands the full text back when you are ready to sit down and stay. Everything it does is in service of reading — not more feeds, not more scroll, just the clearest path to the idea you came for.
