A beautiful desktop app for running local and cloud LLMs. Privacy-first, no terminal required.
Msty is a desktop application that makes running large language models on your own machine actually pleasant. No Python, no command line, no broken dependencies — just download a model and chat. It bridges local models (via Ollama or its own engine) with cloud APIs (OpenAI, Anthropic, Gemini) in one unified, beautifully designed interface, with split-chat comparison, vaults for organizing prompts, and RAG over your own documents.
Who it's for: Privacy-conscious users, researchers, and developers who want local models without the terminal, plus a clean way to compare local vs cloud answers side by side.
Install, pick a model, chat. Msty handles the engine plumbing for you.
Run Ollama models locally or wire in OpenAI/Anthropic/Gemini — compare them in split chat.
Organize prompts and chat with your own files via retrieval augmentation.
Local models never leave your machine; cloud calls are opt-in.
The most approachable way to get into local LLMs without touching a terminal. If you want maximum control and a huge model catalog, raw Ollama + LM Studio is more flexible — but for everyday private chat, Msty is the joy-to-use option.
