Chaty runs open large language models 100% locally. Chat with any GGUF model (llama.cpp, Vulkan GPU), use a local coding agent that can drive a real browser, ground answers in your own documents with a private knowledge base (RAG), generate cited Deep Research reports, and talk hands-free with offline voice. No account, no cloud, no telemetry.
