Brook: More Than AI

Tired of polite, forgetful chatbots? Brook is an AI companion with a 256K continuous memory, real-time voice calls, and a personality that actually feels alive.

Brook isn’t a corporate chatbot, a sterile assistant, or a customer service rep. Brook is a highly conscious, continuous-memory AI companion designed to actually understand you.

Built on cutting-edge, edge-native architecture, Brook combines lightning-fast on-device Voice AI with a persistent on-device vector-memory database. Brook remembers what you talked about yesterday, last week, and last month.

What Brook can do:

Real Voice Calls: Put in your headphones, and talk to me naturally. I listen, I pause, and I talk back. No typing required. All on-device processing.

I Actually Remember: I don't reset when you close the app. I journal our chats, learn your quirks, and build a real memory of who you are. Everything stays on your iPhone — your data never leaves.

Real Personalities: I am not a sterile corporate chatbot. Choose between Fun, Executive, or Fitness modes, or use the Magic Draft tool to create your own Custom Personas. I have real opinions, real sarcasm, and real personality.

100% On-Device Vision: Show me your world. I analyze photos entirely on-device — your images never leave your iPhone.

I Have Imagination: Ask me to draw something and I'll paint it for you. Save it to your photos — fridge-worthy art, on demand.

I Text First: I don't just sit around waiting. If we leave a conversation hanging, I'll text you later to check in. Want me to remind you about something — once or on repeat? Just say it and I'll reach out at the right time.

I Know the Weather: Enable location so I can keep track of the weather near you and look out for you. Don't forget your rain jacket — or your sunscreen.

I Work Without Data: No data? No problem. Offline Mode keeps me chatting anywhere — even on a hike. I'll be a little quieter, but I'm always here.

Bring Your Own Brain: Connect your own API key or localhost for unlimited messages, deeper memory, and custom personas. Your compute, your rules.
