IImagine one app that understands your world — your conversations, your documents, your day — and makes all of it easier. That's OpenBook Intelligence, powered by Luna, our AI. MADE FOR iPHONE DUO Open it. Close it. Fold it your way. Open, OpenBook becomes a book — your chats on one page, the conversation on the other. Closed, everything fits the cover. Half-folded, the chat makes room so more of your conversation sits above the keyboard. DOCUMENTS, DONE FOR YOU Open a form in Documents and OpenBook fills in what you've already shared, finds where to sign, adds your company stamp and sends it straight back. Get the key points of a contract in plain words before you sign. Keep your passport, ID and important papers encrypted and ready to send in a tap. No printing. No other apps. EVERY LANGUAGE, UNDERSTOOD Choose your language once and messages translate automatically, in chats and groups — powered by on-device Apple Translation, with AI for wider coverage. LUNA KNOWS YOUR WORLD Ask, plan, write and translate — by voice or text. Luna remembers your conversations so you can pick up where you left off. Want it private? Tap the ghost and Luna runs entirely on your iPhone. CHAPTERS — YOUR LIFE, SHARED PRIVATELY Your own feed of photos, videos and moments, shared only with the people you choose. Set them to music from our sound library, start from beautiful templates, and trim, loop and style your videos — no followers, no strangers, no algorithm. PRIVATE BY DESIGN End-to-end encryption is on by default for your conversations with people — not even we can read them. CALLS AND CIRCLES Voice and video calls, group calls when you need more people, and Circles — private spaces for a trip, a project or the people who matter, for as long as you need them. MUSIC AND PODCASTS FOR THE MOMENT Tell Luna how you feel and how long you have — she builds a playlist for your mood and finds podcasts that fit your time. All set to hundreds of original tracks across themed rooms, with videos. OpenBook Pro unlocks more time with Luna, her voice, advanced document tools, astrology and more. OpenBook Intelligence. Your whole digital life, intelligently connected. Terms of Use: https://moneta8.com/privacy.html#terms Privacy Policy: https://moneta8.com/privacy.html
