AI runs here. Not out there
Osaurus is a free, open-source, native Swift app that runs local AI entirely on Apple Silicon Macs, keeping data on-device and working offline. It connects one-click to Ollama, MLX, or LM Studio, optionally adds ChatGPT, Claude, or Gemini for cloud tasks, and supports building autonomous agents that can read files, run tools, and execute parallel jobs.
Your Mac. Your AI. Free.
Open models run entirely on your Mac — your data never leaves. Add ChatGPT, Claude, or Gemini when a task needs them, and carry one shared memory across all of them.

What is local AI?
Your AI runs here. Not out there.
Most AI tools send everything you type to a server. Local AI keeps the model on your machine — so your conversations, code, and files stay completely private.
As seen on
Private
Nothing leaves your Mac. No telemetry, no training on your data, no servers in the loop.
Offline
Wi-Fi off. Still works. Models run on your Apple Silicon chip — no internet required.
Fast
Inference runs on your M-series chip. No round trips to a server — results in milliseconds.
Free
MIT licensed. No subscription, no usage caps, no billing. Yours to use and modify forever.
Model support
Local first. Cloud when you need it.
Start private and offline. Reach for the cloud only when a task demands it.
Local — runs on your Mac
Cloud — when you need it
Reads your files. Runs your tools. Remembers your work.
Drop a folder. Give it a job. Osaurus can read, write, and execute — like having a local AI assistant that actually knows your environment.
Agents. Not just chat.
Build agents that run autonomously — voice control, folder watchers, browser plugins, parallel jobs. Let your local AI work while you sleep.
Off the grid. By design.
Wi-Fi off. Still works. Your data stays on your Mac. Nothing leaves unless you say so — not even anonymous analytics.
Open source
Open. Forever free.
MIT licensed. Built in public. Read it. Fork it. Ship with it.
