What is Atomic Chat?
Atomic Chat is a local offline AI chat for macOS (Apple Silicon), Windows, Linux, iOS and Android.Runs fully on-device so user data is not sent to external servers, supporting private local AI and offline inference.
Supports 1,000+ LLMs including LLaMA, Qwen, Mistral, Gemma and DeepSeek, with GGUF, MLX and ONNX formats and Hugging Face model browsing.Includes TurboQuant optimizations to accelerate attention and reduce KV-cache memory for faster on-device inference (reported up to 8× faster attention and lower memory use).
Built-in agent support enables autonomous workflows, persistent memory across sessions, context switching and extended context windows for multi-step tasks.One-click model downloads and native desktop/mobile apps simplify setup and model management for developers, researchers and privacy-focused users.
Open-source codebase provides transparency for audits, customization and integration with local AI toolchains.
