What is Summio?
Summio is an AI-powered iPhone reading app and personal learning companion designed to help people condense long-form content into structured editorial summaries. It supports multiple formats, including books, YouTube videos, articles, and PDFs, translating them into 27 languages.

How to use Summio?
To use Summio, select your source content by searching for a book title/ISBN, pasting a YouTube link, dropping an article URL, or uploading a PDF. Next, choose your preferred summary depth from four available levels (short, medium, long, or detailed). Finally, read the structured editorial summary, chat with the full text using inline dialogue, and save key concepts to your personal library for spaced-repetition practice.
What sources can I summarize with Summio?
Summio supports four main sources: books (via a catalog of 100,000+ titles or ISBN), YouTube videos (via lecture, podcast, or playlist URLs), articles (long essays, magazine pieces, and newsletters), and uploaded PDFs (including research papers and manuals with OCR support).
How does the Dialogue feature work?
The Dialogue feature is a context-aware chat assistant that knows the full text of the source material, not just the summary. It answers your analytical questions and points back to specific passages with citations.
Can I cancel my subscription easily?
Yes, Summio operates with a commitment to zero dark patterns. You can cancel your subscription in one tap directly through your Apple App Store Settings.
