Quick Setup (< 1 hour)

You can use Osaurus to run AI agents directly on your Mac without sending data to external services. The tool provides persistent memory for agents, lets them execute code in a sandbox, and works with any AI model including local MLX models on Apple Silicon. Agents can remember past interactions, run real tasks, and maintain cryptographic identity while keeping everything on your machine. Built natively in Swift for macOS, it offers privacy-first AI agent management.
