Chatagi vs Eira

Own your thoughts. Own your AI. Chatagi is an on-device AI chat app designed for privacy, control, and local intelligence. Instead of sending every conversation to the cloud, Chatagi runs supported AI models directly on your device, giving you a more private space to think, write, explore ideas, and ask questions. Why Chatagi? Private by Design Chatagi is built around local AI. Your conversations stay on your device, and no account or login is required to start chatting. On-Device Intelligence Download a supported model, set it as your default, and chat directly from your device. After setup, Chatagi can run without relying on a constant internet connection. Fast Mode and Thinking Mode Use Fast Mode when you want quicker responses. Switch to Thinking Mode when you want the model to reason more deeply and show a more thoughtful response style. Choose Your Model Chatagi lets you choose the model size that fits your device: Nano: Optimized for efficiency and faster local use. Small: A balanced option for everyday private AI chat. Large: A more capable local model designed for higher-performance devices. A Note on Performance Local AI depends on your device’s hardware. Larger models may respond more slowly because they require more memory and processing power. If a model feels slow or the app becomes unresponsive, switch to a smaller model for a smoother experience. Your thoughts. Your device. Your AI. Note: AI responses are for informational purposes only and do not constitute professional, legal, medical, financial, or other expert advice.
