About

Your company's communication, centralized: every department, office and announcement in one place.

One place for everyone

Departments, offices and teams each have their groups; the company and every office have channels for announcements, with a discussion under every post. A newcomer joins every group of the department in one step, and a person who leaves is removed from all of them at once.

Administration

Owners and administrators invite by link, pin posts, add and remove people and decide who writes in a channel.

Sealed communication

Letters, voice and video calls, photos, videos and files are end-to-end encrypted with post-quantum cryptography: ML-KEM-768 and ML-DSA-65, the NIST standards designed to withstand quantum computers. Nothing readable leaves the devices of the conversation.

Sign in your way

With a phone number, with an e-mail address, or with a 24-word phrase generated on your phone that needs neither. A confirmed number lets the people who have it in their address book find you, and shows you which of your contacts are already here.

Your history stays yours

Conversations live on your devices. An optional daily copy goes only to your own iCloud, sealed with the key your 24 words open. No advertising, no trackers, no third-party analytics.
