Crystal-clear calls
Voice and video, one-to-one or the whole group — with screen sharing when words aren't enough.
Pakistan's own messenger · Now in beta
Talk freely.
Own every word.
ChatT is a fast, beautiful messenger with voice & video calls, groups and channels — and it runs on Internet Computer cloud engines hosted entirely in Pakistan, so your conversations stay in the country.
Everything a messenger should be
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 nationwide communities.
Share anything
Photos, video, files and rich text that look great on every screen — sent at full speed.
Your data stays in Pakistan
Your account, your messages and the files you send live on cloud engines inside the country, not in a foreign data centre. No ads, no tracking, no data mining.

Beta openGoogle'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.

Why can we promise all that? Because ChatT is sovereign: it doesn't run in a foreign company's data centre, but on Internet Computer cloud engines hosted entirely in Pakistan. Your account, your messages and your media are held in smart contracts on machines inside the country, under Pakistani jurisdiction — there's no server bill paid for with your data, and no foreign company holding your conversations.
