Glyph

Features

Whether it's a novel, a textbook, or a comic, you've got an AI co-reader along for the ride. The summaries, visual lookups, and follow-ups are the point; everything else is built to get out of their way.

AI chapter summaries

Two taps to a summary of the chapter you're in. Generated on demand, never sent anywhere you didn't ask for.

Ask follow-ups in context

Highlight a passage and ask what it means. Glyph keeps the surrounding text in context so the conversation actually tracks what you're reading.

AI book summaries

Catch up on premise, themes, and where you are in the arc, without spoiling what's ahead. Perfect when you put a book down for a while.

Bring your own books

Drop in your EPUB, PDF, and CBZ files and start reading. Adjustable text size, customizable fonts, light and dark themes.

Private by default

Your library never leaves your device. AI requests are anonymized and not retained.

iCloud sync

Library and reading position sync across your devices. No accounts, no servers. Just your iCloud.

Built for studying

Make sense of dense material. Get a chapter summary before a deep read, ask follow-ups on terminology, and review whole chapters before an exam, without leaving your textbook.

Understands graphs & images

Ask about a chart, diagram, or illustration on the page. Glyph reads the visuals in your textbook so you can ask "what's this graph showing?" or "explain this figure" inline.

Comics & graphic novels

CBZ comics and manga work too. Same library, same reader, with AI on tap when you want context on a scene or panel.

Why we built Glyph

Reading apps hadn't really changed in years. Fine at turning pages, and not much else. The problem was simple: put a book down for a few weeks, come back, and you'd have no idea who anyone was or where you'd left off. So you'd reread the same chapters, or quietly give up. Glyph started as the fix for that. A two-tap summary to get you back into the story.

The more we used it, the more it became a reading companion instead of a bookshelf. A dense passage in a textbook, a term you didn't recognize, a chart you couldn't parse. We wanted to ask right there on the page, without breaking off to a chat app or a search tab. Glyph keeps what you're reading in context, so the answers actually track the book in front of you.

We also wanted AI that respects the reader. Your library never leaves your device, requests are anonymized and never retained, and there's no account, no tracking, no ads. Just you and the book. Glyph is built for people who love to read, and we're only getting started.
