Own your thoughts. Own your AI.

Chatagi is built on a simple principle: your digital space should be as private as your physical one. It operates entirely within the secure environment of your device, ensuring your AI experience remains a personal, internal dialogue.

Why Chatagi?

A Private Mind: Chatagi lives entirely inside your device. It doesn’t "talk" to servers, it doesn't report back, and it doesn't share your ideas. It is a digital brain that thinks only for you.

Total Autonomy: Because the AI is local, you have absolute ownership of your conversations. No accounts, no logins, and no "cloud" middleman.

Chatagi uses a custom-built engine for a fluid, on-device dialogue that feels immediate. Because it’s 100% local, it is immune to the frustrations of modern connectivity. Whether you’re on a plane, in a remote area, or on slow Wi-Fi, Chatagi delivers a steady, reliable response—no internet required.

Choose Your Intelligence

To get started, download your preferred model and set it as your default. You can switch models at any time in the settings to match your device’s power:

Nano (0.6B): Optimized for efficiency. Best for devices with less than 8GB of RAM.

Small (1.7B): A balanced mind for mid-to-high-end hardware. (Recommended: 8GB+ RAM for the best experience).

Large (3.3B): Our most capable local intelligence. Designed for high-performance devices with 12GB–16GB+ of RAM.

A Note on Performance
Local AI is hardware-intensive. Even on high-RAM devices, larger models may feel slower as they prioritize reasoning depth over raw speed. If a model feels slow or the app becomes unresponsive, we recommend switching to a smaller version (like Nano) for a snappier, more fluid experience.

Your thoughts. Your device. Your AI.
