What is Msty?
Msty is the local LLM client that takes the chat UX seriously — split-screen comparison chats, parallel responses from multiple models, knowledge stacks (local RAG over your files), and prompt libraries. Free for personal use; paid Aurum tier unlocks team features.
Pros & cons
Pros
- Split-chat / parallel-model comparison is unique
- Knowledge stacks make local RAG genuinely usable
- Beautiful UI — feels more like a 2026 product than most OSS alternatives
Cons
- Closed source
- Aurum tier behind a paywall (acceptable, but worth knowing)
What's actually free?
Free for personal use; Aurum tier US$50/yr for advanced features.
