Athene on iPhone, the shelf

Athene.

A reader for your own books.

Coming to the App Store. Free. EPUB and PDF, on iPhone and iPad.

A page of Walden in the Sepia theme

Pages, not scrolls.

Books are laid out as real pages and turned with a swipe. Change the type mid-chapter and the words reflow without losing your place.

A highlighted passage in the Night theme

Mark it up.

Press and hold to highlight or add a note. Bookmarks, the table of contents and search are a tap from the page.

Ask the Owl, answering a question about the page

Ask the Owl.

A reading companion for the passage in front of you: who this character is, what that word meant in 1890. It runs on your device with Apple Intelligence, on your own Ollama server, or with an API key you bring.

The shelf on iPad

Your calibre server, on the shelf.

Point Athene at your calibre-web or OPDS library and browse it as if it were on the device. Downloads cross your own network and nobody else’s.

Free. Forever.

Everything Athene does today is free, with no subscription and nothing collected. No account. No analytics. No server but yours.
