What Atomic Chat is

Atomic Chat runs language models locally on your device, allowing chat, document analysis, and a local API to work offline after a model is downloaded. It supports more than 1,000 models, including Llama, Qwen, DeepSeek, Mistral, Gemma, and Phi. You can upload files and ask local models to examine contracts, medical records, financial files, and other documents. MCP connectors link tools such as Notion, Google Drive, Slack, GitHub, Figma, and Supabase through STDIO, HTTP, and SSE. A local OpenAI-compatible endpoint supports agent tools including OpenClaw and Hermes. Atomic Chat lists web search, app integrations, and mobile apps, and runs on Windows, macOS, Linux, iOS, and Android. It is open source under Apache-2.0. The free plans cost nothing forever, require no account or subscription, and list no usage caps. Anonymous app analytics may be sent.
