Msty

Anyone who wants to run several AI models from one desktop app, including ones that work offline, will find Msty a reasonable fit.

Msty is an AI chatbot and model manager that puts local and online language models in a single interface, with split chats so you can compare answers side by side.

Personal use is free, and the free plan has no time limit.

Paid plans add things you may want for work.

Aurum Annual costs $99 per user per year and includes Azure OpenAI integration, advanced response metrics, Vapor Mode, code themes, a commercial use license, and use on up to 2 devices.

Aurum Lifetime is a one-time $199 payment that covers all of that, plus future updates and access to the upcoming Msty Studio.

Neither paid plan requires sign up.
