Atomic Chat is a free, open-source AI chat application that runs language models entirely on your device. No account, no servers, no data collection—after downloading a model, it works fully offline. Choose from 1,000+ open models (Llama, Qwen, DeepSeek, Gemma, Mistral, and more) with one-click download from Hugging Face, and chat with unlimited messages at no cost. Available on macOS, Windows, Linux, iOS, and Android. Built-in TurboQuant compresses the KV cache to make long contexts usable on consumer hardware, and one-click agent runners (Hermes, Cline, etc.) let you extend it into local agent workflows. Apache-2.0 licensed.
