Athena

A library that fits in your pocket.

Download books once, then read and ask questions anywhere, with no connection.

Athena's AI librarian runs on your iPhone. It searches your books and tells you which sources it read for each answer. Nothing you ask leaves your device.

• Books from Wikipedia, WikiMed, Appropedia and more, kept on your phone.
• Answers from the books, with the sources listed.
• Explore: Article of the day, Today in history and Link Odyssey.
• No account, no ads, no tracking.

The AI needs an iPhone 11 or later. Answers can be wrong; check important facts in the sources.
