Introducing OpenBook Intelligence — powered by Luna, our AI. Your conversations, your documents and your day, all in one place, and all a little easier. - Documents, done for you — open a form and it fills in what you've already shared, finds where to sign and sends it straight back. No printing, no other apps. - Contracts made clear — the key points and anything unusual, in plain words, before you sign. - Every language, understood — choose yours once and messages translate automatically, in chats and groups. - Luna knows your world — pick up any conversation where you left off, by voice or text. Want it private? She runs entirely on your iPhone. - Calls, Circles and music — group calls, private spaces with the people who matter, and music shaped to your mood. Faster, lighter on battery and more secure throughout.
