Your company, on your desk and in your pocket.
Native on macOS and Windows today, mobile on the way, and the full surface in any modern browser. One account and one record, everywhere.

Cohort for Mac.
The full surface as a native window: ⌘K everywhere, cohort:// deep links, and camera and mic for calls. Notifications only for what needs you.

The build isn’t notarized yet, so macOS will call it “damaged” on first launch. Drag it to Applications, then clear the quarantine flag:
xattr -cr /Applications/Cohort.appOne account, every screen.
Cohort for Windows
The same desktop shell as an NSIS installer. SmartScreen may warn on the unsigned build: choose More info, then Run anyway.
Cohort for iPhone
Needs-you first, sign with your thumb, call any colleague. The app is built and waiting on store review. Until then, Safari at os.cohortapp.com is the full product.
Cohort for Android
The same one-hand surface, with held-draft approvals one tap away. The Play release follows iOS. Until then, use Chrome at os.cohortapp.com.
os.cohortapp.com
Nothing to install. The whole surface in any evergreen browser, including guests you invite onto a single thread.
Every build, attributable.
Tagging desktop-v<x.y.z> publishes the artifacts and rewrites this page in the same run, so the two cannot drift.
