Who It's For

Why Personal Productivity & Executive Assistants choose this tool

🎯
Built for
Knowledge workers who want private chat and knowledge across several models
In-Depth Overview
Msty is for people who want one place to chat with local and online models while keeping control of data. Studio's free desktop tier lets you chat with local and online models, run Persona and Crew Conversations, use Agent Mode, build Knowledge Stacks for retrieval and work in Prompt, Persona, Skill and Media Studios. The feature matrix lists local inference engines (Ollama, Llama.cpp, MLX), split chats, user memories and MCP tools, though several are marked Limited on Free. Paid Aurum adds Studio Web, Azure and Bedrock providers, Studio Assistants, Shadow Personas, Turnstiles workflow automation, Insights and Forge Mode. Pricing is $149 per user per year for Aurum or $349 one-time for Aurum Lifetime, while Enterprise and Teams needs a minimum of 5 seats and adds SSO, role-based access and audit logs. The company states zero product telemetry and a DPA is available, but also says formal SOC 2 and ISO 27001 certification are not yet complete, which matters in regulated teams. Msty Stack is listed as coming soon, and the pricing view for Go and Nexus was not captured here. If you want a hosted assistant with no setup, a mainstream chatbot is simpler, since Msty asks you to bring your own models or provider keys.
