Where language stops being a barrier.
01 — The Problem
None of them protect you. All of them own you.
Fragmented Identity
Your messages live in one app, your music in another, your stories somewhere else. Every platform watches, logs and monetises your daily life.
Privacy Theatre
Every platform claims encryption — and technically most mean it. But the key still lives in software they control. One court order, one compromise, and your privacy is gone. OpenBook’s key is mathematically split — no single party, including us, holds it whole.
No AI Culture Layer
AI is defining the next era of music and communication. Existing platforms are retrofitting. OpenBook was designed for this world from day one.
02 — The Product
OpenBook is not a messaging app with features bolted on. Privacy, music, social and AI were designed together from day one — as a single coherent experience. Built entirely in-house, from concept to App Store. Android listing on Google Play within weeks.
Shamir Encryption
Shamir's Secret Sharing splits your key across three locations — device, user, server. No single party, including us, holds the complete key. Device recovery shipping soon. OpenBook Zero Protocol →
Live · Recovery Shipping SoonExclusive AI Music
A full catalogue of AI-generated artists — complete with personas, bios and artwork — owned entirely in-house. Larger than most independent labels at launch.
Void
Moments that exist only in the moment. Send a thought in any language — it appears to your reader in theirs and yours, side by side. No archive, no screenshots. Then it's gone.
Borderless Chat
Built for a world that speaks every language. Type in Arabic, it lands in English. Reply in Hindi, they read it in Thai. Conversation flows; the translation disappears. In India, Thailand, the Philippines, and across the GCC — this is not a feature. It is the entire point. Thirty languages live today, more shipping.
Calls You Asked For
No cold calls. No interruptions. Calls require a request, recipients confirm, then the line opens. The first messaging platform where your phone respects you.
Plus: in-app document signing with company stamps, multi-signature flows, initials, and seamless PDF ↔ image conversion. The workflow tools chat apps forgot — no third-party plugins, no leaving the conversation.
03 — Meet Luna
Every OpenBook user has their own AI — not a chatbot, not a bolt-on. Luna is context-aware, lives inside every conversation, and makes communication effortless for everyone.
Your Personal Assistant
Context-aware. Ready to help with most of your day — drafts, plans, reminders, summaries, translations. You choose what she sees. Read your chats? Only if you say so. Off-limits topics? You decide. The first AI companion designed around consent, not surveillance.
Luna Local · Sovereign AI
Sensitive conversations run on Apple's on-device Foundation Models — they never leave your iPhone. Frontier cloud models available for heavy lifting, but always your choice. The only AI companion built around real data sovereignty: sensitive conversations run on Apple’s on-device Foundation Models and never leave your device. Cloud models are available for heavier tasks — always your choice, never ours.
04 — Revenue
Luna creates the willingness to pay. The surrounding platform creates the reason to stay. Every revenue line below flows from that order.
Free gets them in. Luna converts them. OpenBook’s free tier is genuinely valuable — messaging, music, Void, and an introduction to Luna. The upgrade moment is simple: users hit Luna’s conversation limits. OpenBook Pro at $9.99/month unlocks unlimited AI conversations, extended memory, voice mode, and higher token limits — plus Doc Signer for professional document workflows and Vault for secure file storage. Character.AI, Replika, and Pi have validated $8–15/month willingness-to-pay for AI alone. OpenBook justifies every cent of that and more.
The free tier creates the habit. The habit creates the upgrade. Messaging, music, and a daily taste of Luna keep users engaged long before they pay. That daily engagement is what turns a Luna limit into an immediate upgrade — and what keeps Pro subscribers around long-term.
UAE is the launchpad, not the limit. We start from home — regulatory clarity, GCC capital access, and an 88% expat population already messaging across language lines daily. But OpenBook is built for anyone who lives across languages. India’s 22 official languages. Thailand, Indonesia, the Philippines. The South Asian and Southeast Asian diaspora in the UAE are those markets — when they bring OpenBook home, the network follows.
A second revenue stream is planned — send gold by gram inside a conversation, via a licensed regional partner. Transactional take-rate income on top of subscriptions, no impact to the core model.

Every individual feature exists somewhere. This exact combination, in one private owned experience — nowhere.
