# Msty review

A private, local-first AI desktop app for chatting with local and cloud models side by side, with an optional paid tier for enterprise gateway and knowledge features.

By Noah — last updated & pricing verified September 15, 2026.

> **Msty** is a desktop AI chat application that runs local language models and connects to cloud providers from one interface, aimed at users who want a polished, no-command-line way to try local LLMs.

Its core feature is "parallel multiverse chats": running the same prompt against multiple models side by side to compare responses, plus the ability to switch models mid-conversation without starting over. Local inference uses a bundled MLX (Apple Silicon) and llama.cpp engine, so users can download and run open models with a single click instead of separately installing Ollama or LM Studio; more than a dozen cloud providers (OpenAI, Anthropic, DeepSeek, and others) can be connected in the same workspace. Msty also supports uploading local documents for retrieval-augmented chat, with files staying on the user's machine.

Msty is developed by CloudStack, LLC, is closed source, and is distributed as a desktop app for Windows, macOS, and Linux. The company has expanded the product line into Nexus (a free local model gateway), Go (a beta bounded-agent product), and an enterprise tier for teams needing SSO and audit logs.
