b/AI: Private AI Chat

Chat with AI completely privately. Free to download, no cloud servers, no data collection. Your conversations stay on your device, always. Private AI made simple.

Meet b/AI - Your completely private AI chat companion that respects your privacy.

FREE TO DOWNLOAD No cost to get started. No monthly subscriptions required.

TRULY PRIVATE CONVERSATIONS Every conversation happens entirely on your device using Apple's on-device AI models. Your chats never touch the internet, never reach our servers (we don't even have any), and are never seen by anyone but you.

Unlike other AI chat apps that send your conversations to cloud servers, b/AI processes everything locally on your iPhone or iPad. You're not the product - you're the customer.
