CosmicChat
The app that runs CosmicFish on your iPhone. Models run locally on the device — no cloud, no account, no data leaving your phone.
On-device
Supported models run entirely on your device. Optimized Core ML builds keep them fast and battery-conscious.
Private
No account, no tracking, no telemetry. Your conversations stay on your phone.
