The thing most people get wrong about Telegram is that its regular chats are not end-to-end encrypted — only Secret Chats are, and you have to start one on purpose, on the device that has it. In Tex there is no such switch.
Groups, media, reactions, GIFs, and messages that delete themselves.
It runs in a browser without installing anything.
Free.
What Tex does differently
Every one-to-one and group chat is end-to-end encrypted, not just the ones you remember to open as secret.
No phone number to sign up.
Gotex and Radar: leaving something in a place, and seeing who is around.
Where Telegram is better
This section is here because a comparison where the author wins everything
is not worth reading. These are real, and they are the reasons to stay where you are.
Telegram's groups, channels and bots are in a different league. Tex has none of that.
Telegram syncs everything across all your devices. Tex's encryption keys live on the device that made them, which is the price of the server never being able to read you: a new device cannot open old encrypted messages.
