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.

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.

Reads your files.
Runs your tools.

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.

Osaurus dinos with devices

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.
