Full description
Cloud sync makes switching between phone, tablet and desktop nearly instant. Large file transfers, huge groups, broadcast channels and a lively bot ecosystem are all mature.
One important caveat: regular cloud chats are not end-to-end encrypted by default — only Secret Chats are. Public channels also vary widely in reliability, so verify information independently.
It behaves more like a mix of channels, communities and cloud storage than a conventional messenger, and its usefulness depends on whether your contacts are there.
