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.
