# Msty

> Private AI workspace for local and online models

Msty is a family of privacy-focused AI apps from CloudStack, LLC, led by Msty Studio, a desktop workspace for chatting with local and online models. Studio adds side-by-side split chats, personas, an agent mode, document-grounded Knowledge Stacks and image generation, and it keeps data on your own device. The desktop app is free for personal use, and an Aurum license permits commercial use and adds a browser version and advanced features. Msty Go, a separate agent app, is in beta.

## Ways to pay less

- **Aurum Lifetime for a one-time payment** (Lifetime license): Aurum Lifetime costs $349 per user once and includes lifetime updates and access, against $149 per user per year for the Aurum subscription. Source: https://msty.ai/pricing/
- **Enterprise bundle across Msty products** (Other savings): Msty offers a single enterprise agreement that combines Studio, Go, Nexus and Stack, priced by seat count and deployment shape instead of as separate product plans. Source: https://msty.ai/pricing/

## Key features

- **Local and online models in one hub:** Runs local models through Ollama, llama.cpp and MLX and connects hosted providers, so both kinds sit in the same organized model list.
- **Split Chats:** Runs models side by side on the same conversation so you can compare tone, depth and accuracy without losing context.
- **Agent Mode:** Carries out multi-step, tool-aware tasks instead of single prompts. MCP tools are connected through the Toolbox, which is limited on the Free plan.
- **Knowledge Stacks:** Grounds answers in your own documents and notes with organized, source-aware retrieval. The feature is marked Limited on the Free plan.
- **Personas and Crew Conversations:** Personas are reusable assistants built in Persona Studio, and Crew Conversations put several of them in one thread to work on a task together.
- **Data kept on your device:** Studio stores data locally and does not sync it between devices; Studio Web keeps its data in the browser's local storage. Msty says it sends no product telemetry.

## Good for

- Individuals who want local and hosted models in one desktop app
- Privacy-sensitive work where data should stay on the device
- Buyers who prefer a one-time lifetime license to a subscription

## Worth knowing

- Msty's terms limit the Free tier to personal, non-commercial use; work that earns revenue requires an Aurum or Enterprise license.
- The browser version, Msty Studio Web, needs an Aurum license, and several Free-plan features, including Knowledge Stacks and MCP tools, are marked Limited.
- Data does not sync between devices, an Aurum license covers 2 desktop devices, and Enterprise & Teams plans start at 5 user seats.
- Msty states that formal SOC 2 and ISO 27001 certification are not yet complete.
