CosmicChat by Mistyoz AI

Chat with LLMs offline

Free · Designed for iPad. Not verified for macOS.

Meet Ceres and Eris, bigger, smarter, fully offline AI. CosmicChat lets you have conversations with CosmicFish, a large language model that runs entirely offline on your device. The app features two CosmicFish model variants: Ceres, fast and lightweight for everyday chat, and Eris, the flagship model with deeper reasoning and broader knowledge. Pick the right balance of speed and capability for your needs. All conversations happen locally on your device using on-device machine learning and your Neural Engine, ensuring complete privacy and data security. Nothing you type is ever sent to a server. You can switch between Ceres and Eris at any time based on your performance needs and device capabilities. The app includes conversation history management, customizable chat interfaces, real-time response generation, and export functionality. CosmicChat is designed for users who want access to a powerful on-device language model while maintaining full control over their data and conversations.
