Download Octuo

Octuo is a personal operating system. Pick your platform.

macOS

Signed with an Apple Developer ID and notarized by Apple. The first time you open it, macOS asks you to confirm — that's Apple's standard check for apps downloaded from the internet.

Checking the latest signed release…

Confirming the current macOS build needs JavaScript, because we verify the release signature in your browser. Email us for a direct link: support@tutuo.ai

iOS / iPadOS

The Octuo app for iPhone and iPad, signed in to the same account as your Mac and the web.

We'll link to the App Store listing here as soon as it's live.

Web

The full Octuo Web client is not available in production yet.

Web access is not available yet. We'll enable it in a future release.

Other platforms

Octuo is currently Apple-first. Linux and Windows desktop clients are not on the V1 roadmap. See the cards above for current macOS, iOS, and Web availability.

If your team genuinely needs a Linux or Windows client, send a one-line email to support@tutuo.ai with the use case — it helps us prioritize.
