About Sentient OS
Sentient OS is a desktop assistant for Mac that builds a private picture of its user's work and life from local sources, then helps act on it. An on device model reads notes, messages, emails, calendar entries, screenshots and files, and assembles that knowledge overnight so it is ready for the day ahead.
The product has two main modes. Sidekick takes a handed off task and carries it out on the computer using its own cursor, a form of computer use that already has context about the person. Double Tap drafts a reply to an email or message in the user's own voice, which the user can send in two taps. The site also shows proactive suggestions, such as flagging that a subscription is about to renew or pulling together flight options and a budget from a group conversation.
It is aimed at individual Mac users who want to hand off routine computer work and communication. The app downloads for macOS and can be installed with a Homebrew cask, and the vendor describes it as open source. A Windows version is listed as a waitlist.
The vendor does not publish a pricing page or paid plan prices. The site advertises free access for life to early adopters through an in app code.
