What it is
Msty is a privacy-first AI desktop workspace from CloudStack, LLC. Its main product, Msty Studio, lets you chat with local models through Ollama, llama.cpp or MLX and with online providers in the same app, compare answers in split chats, and organize work into workspaces and projects. It includes knowledge stacks for retrieval, persona and crew conversations, agent mode, MCP tools and studios for prompts, skills and media. The wider Msty family adds Go for bounded task agents and Nexus, a local gateway for model keys and policies. Studio is free for core desktop use, Aurum costs $149 per user per year, and a lifetime license is $349.

Editor's notes
More context from AI BirdView
Msty is a privacy-first AI workspace for people who want to use local models and cloud models in one polished desktop app. Its Studio app sits on top of runtimes like Ollama, llama.cpp and MLX, and also connects to online providers, so you can compare a private local model against a frontier model in split chats. Msty leans toward power users, with personas, knowledge stacks and workflow tools that go well beyond a basic chat window.
What is Msty used for?
Msty is used as a daily AI desk for research, writing and analysis where some material is too sensitive for a cloud chatbot.
- Chatting with local models and online models from the same interface
- Running split chats to compare answers from different models on one prompt
- Building knowledge stacks from documents for retrieval
- Setting up personas and crew conversations where several personas collaborate
- Using agent mode and MCP tools for multi-step tasks
- Managing prompts, skills and media generation in dedicated studios
Who Msty is best for
Msty suits consultants, lawyers, researchers and educators who handle confidential material, as well as AI enthusiasts who like to test many models. Its team edition targets regulated organizations that want SSO and audit logs. Casual users who just need a single assistant, or anyone who does not want to think about which model to pick, may find it more than they need.
Msty pricing
Msty Studio has a Free plan at $0 forever with core desktop features: local and online models, persona and crew conversations, agent mode, knowledge stacks, and limited versions of several studios. Aurum costs $149 per user per year and adds Msty Studio Web, Azure and Bedrock providers, Studio Assistants, Shadow Personas and power-user features such as Turnstiles, Insights and Forge Mode. Aurum Lifetime is a one-time $349 per user. Enterprise and Teams plans need at least five seats and add SSO, user management, role-based access and audit logs at custom prices. Msty Go is in free beta. Figures are from the pricing page as of October 2026.
Limitations to keep in mind
- The free tier limits several features, including crew conversations and knowledge stacks
- Local model quality depends on your hardware
- Msty states that formal SOC 2 and ISO 27001 certification is not yet complete
- The product family (Studio, Go, Nexus, Stack) can be confusing at first
Msty vs alternatives
ChatGPT and Claude are the better choice for people who want one strong hosted assistant with no setup. Poe gives access to many hosted models in a simple consumer app, but without local models. Together Chat is a quick browser playground for open models. Msty wins for users who want local privacy and cloud models side by side, with deep customization and a one-time license option.
Tips for getting started with Msty
Install Ollama or use Msty's built-in local engine first, then add one online provider key so split chats have something to compare. Create a knowledge stack for a single project before importing large document sets. Try the free tier for a few weeks before deciding between yearly Aurum and the lifetime license.
