Turn any book into a conversation. Glyph is a reader with a companion built in. Whenever a chapter loses you, a passage tangles you up, or a question pops into your head, the companion is right there on the page, ready to summarize, explain, or answer, so you keep moving instead of putting the book down. A companion that reads along with you • Summarize a chapter or a whole book in seconds, so you can catch up or decide what to read next. • Highlight any passage and ask what it means. The companion keeps the surrounding text in context, so follow-up questions actually track what you're reading. • Stuck on a chart, diagram, or panel? Ask about the visuals on the page and get a plain answer. • Coming back to a series after a while? Get a spoiler-aware recap of where the story left off. A reader worth staying in • Adjust font size, line spacing, margins, text alignment, and brightness until the page feels right. • Read paged or in a continuous scroll, with light, dark, and warm themes. • Highlight, bookmark, and take notes, then jump back to any of them instantly. • Search the full text of a book to find that one line you remember. Bring the books you already have • Open EPUBs, PDFs, and CBZ comics from Files, email, or any app that can share them. • Scanned PDFs are read on device so you can search and summarize them like any other book. • Comics get their own reader: page spreads or vertical scroll, pinch to zoom, and right-to-left support. Picks up wherever you are • Your reading spot, bookmarks, highlights, and the companion's summaries and chats sync across your iPhone and iPad with just your iCloud account. • Switch devices mid-chapter and continue at the same spot. • Delete and reinstall, or re-add a book you had before, and everything comes back with it. Private by design • Your library stays in your own iCloud account. We don't sell your data and we don't use third-party trackers or advertising.
