A private AI personal assistant · Mac today, Windows on the way
Roz keeps up with your life,
so you don’t have to.
An owner-centric assistant that understands the people, promises, and priorities behind your day — running quietly on your own machine, on your terms.
Local-first · your data stays on your machine · your keys never leave it
Built to be trusted with everything.
Most assistants earn their keep by sending your life to a server. Roz earns it without ever leaving your desk.
Local-first
Your life stays on your machine
Roz reads your calendar, contacts, mail, and chat locally. Your data lives on your Mac — not in our cloud, and it stays yours whether or not you're online.
Bring your own key
We're never in your data path
Point Roz at your own model provider and your prompts go straight from your machine to your key. No proxy, no copy, no retention on our side — by construction, not by policy.
Cloud only on your say-so
And even then, a zero-retention relay
Prefer bundled cloud models? They run through a zero-retention relay that never stores prompt bodies — and only ever on your say-so, never by default.
Meet the assistant built to show its work.
Free and local to start — hosted Base at $9.99/mo, Pro at $29 when you want the depth. On Mac today, with Windows on the way.
