Atomic Chat

Atomic Chat is an open-source local AI application that runs language models directly on a user’s device instead of sending conversations to a cloud AI service. It provides access to more than 1,000 open models, including Llama, Qwen, DeepSeek, Gemma, and Mistral, with one-click model downloads. Users can chat, analyze files, build local agent workflows, and work without an internet connection after downloading a model. Atomic Chat also supports MCP connections, allowing local models to work with tools such as Notion, GitHub, and Google Drive while keeping the interaction on the user’s hardware. It is available for macOS, Windows, Linux, iOS, and Android.
