We file it under Local LLM tools, the category of tools to run a model on your own machine, and it also overlaps with general AI chatbots and note-taking and knowledge bases. The category lists 6 verified tools on this site.
The publisher is CloudStack, LLC, based in United States.
Who is it for?
It is mostly useful to these profiles: developers, researchers, and freelancers. The need it covers is simple to state: run a model on your own machine.
Msty is a good candidate if:
- you want to try before paying
- you must keep your data in Europe or on your own machine
Before deciding, run a trial on a real task and measure the time saved: it is the only criterion that really counts.
How much does Msty cost?
Pricing model: freemium (limited free use, then paid). A free plan is offered, usually limited in volume or features.
The first paid plan costs $149 per year (Studio Aurum, per user, billed annually), according to the pricing page, checked on October 24, 2026.
Per month, that is cheaper than the category median ($20 per month, based on tools with a published price).

Data and privacy

Local processing is the most favourable case: your files do not leave your machine for the features concerned.
Exporting your content: Markdown, JSON. Being able to get your data back makes switching tools easier later.
Three habits apply to every AI tool:
- turn off the use of your content for training if the option exists
- use a work account separate from your personal account
- review everything the tool produces before publishing or sending it
