SageChat: Private AI Chat

Now with DeepSeek V4.1 Flash. Bring your own key for fast reasoning, coding, and everyday AI chat in SageChat’s private, flexible workspace.

Chat with AI on your iPhone without handing over your keys.

Run supported models on-device. Or bring your own API key for OpenAI, Anthropic, Google, xAI, DeepSeek, Moonshot, and Z.ai. Keys stay on your device. Providers bill you directly. No markup.

Compare models side by side. Attach photos and files. Turn a voice note into a prompt.

WHY INSTALL • On-device / local models for private chat • Bring your own key when you want a cloud model • Multi-model compare in one workspace • Voice notes, photos, and documents • Web-enabled models where the provider supports it

HOW PRIVACY WORKS • On-device chat keeps prompts local • Advanced Lab keys stay on your device and are not sent to SageKey Labs • Advanced Lab requests go directly to the provider you pick • Managed Sage is an optional hosted path if you do not want to add a key. It is not required to install or to chat on-device.

Start on-device. Add a key only if you want one.

SageChat Pro is an optional auto-renewing subscription. Payment is charged to your Apple Account. Subscriptions renew unless canceled at least 24 hours before the end of the current period. Manage or cancel in your App Store account settings.
