Osaurus

Run AI models and agents on your own Mac

MacFree, open source

The verdict

Running AI on your own Mac, with no cloud account needed, is what Osaurus does. It works offline once a local model is loaded, remembers your conversations on the Mac, and can work from a folder of your files. It asks before editing anything and keeps changes in a folder you choose. You can also connect cloud models, with a panel that shows what left your computer.
