AI chat that respects your privacy. Chat uses Apple's on-device intelligence to have helpful conversations without sending your data anywhere. No cloud servers. No accounts. No subscriptions. Everything stays on your iPhone. Why Chat is different: Completely Private — Your conversations never leave your device. No data uploaded, shared, or analyzed. No Account Required — Open and start chatting. No sign-up, email, or phone number needed. No Subscription — One download, unlimited conversations. No fees, token limits, or upsells. Remembers What Matters — Learns your preferences over time without compromising privacy. Smart Summaries — Automatically summarizes past conversations for context without storing everything. Works Offline — Chat anytime, even without internet. Powered by Apple Intelligence Chat uses Apple's built-in language model, the same technology behind iOS features. Fast responses, strong privacy, no third-party dependencies. Your data, your device In a world of cloud-based AI that harvests conversations for training, Chat takes a different approach. Your words are yours. We can't read them. We don't want to. Download Chat and experience AI the way it should be: helpful, fast, and completely private.
