Brook: More Than AI

Meet Brook — an AI companion that actually feels personal. Brook is built for real conversation: the kind where you can talk naturally, pick up where you left off, and shape how your companion interacts with you. Brook adapts to you — playful, focused, supportive, practical, or completely custom. Talk by voice, chat by text, share photos, set reminders, generate images, and build an ongoing memory together — all from your iPhone. Brook isn’t just another chatbot. It’s designed to feel present, useful, and yours. Why people use Brook: Natural Voice Conversations Talk to Brook naturally by voice — and interrupt whenever you want. With barge-in, you don’t have to wait for Brook to finish speaking before jumping back into the conversation. Memory That Builds Over Time Brook can remember past conversations, details, preferences, and ongoing threads, so you don’t have to start from zero every time you open the app. Private by Design Brook is built with on-device intelligence and local memory at its core. Many features run directly on your iPhone, keeping your personal context close to you. Brook Adapts to You Customize how Brook interacts with you. Make Brook warmer, sharper, calmer, more playful, more focused, or create something entirely your own with Magic Draft. Photo Understanding Show Brook what you’re looking at. Brook can analyze images and talk with you about what’s in them. Imagination on Demand Ask Brook to draw, imagine, or create a visual idea, then save the result to your photos. Reminders & Follow-Through Brook can help you remember what matters — from one-time reminders to recurring check-ins and ongoing conversations. Weather-Aware Context With location permission, Brook can understand your local weather and use it naturally when it matters — like reminding you about rain, heat, or changing conditions. Works Offline Brook includes an offline chat mode, so you can keep talking even when you don’t have an internet connection. Bring Your Own AI Advanced users can connect supported API keys or local endpoints for more control, flexibility, and their own compute setup. Brook is for people who want AI to feel less like software — and more like something that understands their rhythm. Download Brook and start building a companion that feels like yours.
