Other platforms

Octuo is currently Apple + Web only. Linux and Windows desktop clients are not on the V1 roadmap. iOS and macOS are the primary client surfaces; the web app is the cloud-only equivalent.

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.
