Now in beta on iOS & Android

Talk freely.
Own every word.

ChatT is a fast, beautiful messenger with voice & video calls, groups and channels — and no company sitting between you and the people you talk to.

Everything a messenger should be

Crystal-clear calls

Voice and video, one-to-one or the whole group — with screen sharing when words aren't enough.

End-to-end encrypted

Your messages and media are sealed on your device. Only the people you send them to can open them.

Groups for your people

Private group chats for the family, the team, the trip — invite-only, and yours.

Channels for everyone

Public channels to broadcast, follow and discover — from neighbourhood news to global communities.

Share anything

Photos, video, files and rich text that look great on every screen — sent at full speed.

Your data isn't for sale

No ads, no tracking, no data mining. ChatT isn't funded by watching you — because nobody owns it but its users.

Google's closed testing takes three quick steps. Use the same Google account your phone's Play Store uses — otherwise Play won't recognise you as a tester.

  1. 1Join the testers group — one tap, this tells Google you're allowed in.
    groups.google.com/g/chatt-beta →
  2. 2Accept the test on the Google Play testing page.
    play.google.com/apps/testing →
  3. 3Install ChatT from the Play Store link that page shows you.
Join the Android beta

The Play Store listing only appears once you've done steps 1 and 2 — it's invisible to everyone else.

Why can we promise all that? ChatT doesn't run in a corporate data center. It runs on the Internet Computer, a decentralized public network — so there's no server bill paid for with your data, and no single company that can read, sell or switch off your conversations.
