Select a word, sentence, or full paragraph in the reader. Ask Syllory to explain the passage as a whole, or choose from 32 translation language options and translate with the surrounding text in mind.
Runs with Apple Foundation Models when Apple Intelligence is available on a supported Mac with macOS 26 or later.
“The handwriting leaned sharply to the right, with careful loops around each name. Most people had come to borrow a book. A few had asked for a map, a quiet chair, or simply a place to sit until the rain stopped.”
The careful handwriting makes the ledger feel personal and preserved. People came to the library for more than books: they also needed guidance, quiet, or a place to wait out the rain.
Your books stay in a local library, with a separate reading place and page setup for each title.
Import EPUB or FB2 files from your own collection. Your place and reading settings are saved for each book, with no in-app store, account, or cloud sync.
Choose a typeface and size, tune paragraph spacing from minimal to relaxed, adjust line spacing, and switch between one or two pages.
Move between Light, Sepia, Midnight, and Mint across the library and the reading view.
Keep the book at the centre. Reading controls fade out of the way, then return when you move the pointer.
Reading layout
Use a single page when you want a narrow, quiet column. Choose two pages for the feeling of an open book. The layout adapts as the window changes size.
Keep track of what's in progress and return to the saved place in any book.
A direction we're exploring: read the original beside an AI translation, then select a word on either page to find its match and understand it in context.

Imported books, reading position, and preferences stay in the local library on this Mac. When Apple Intelligence is available on a supported Mac running macOS 26 or later, selected text and nearby context are processed by Apple’s on-device Foundation Models. Syllory does not send them to its own server.
