Chattin has been shut down. I might continue with the project in the future, but for now I won't.
Chattin is an application to talk with other people. You can join different rooms to talk with different people.
Download from github releases
Or build yourself (on arch linux) using
git clone https://github.com/Robin-floss/Chattin
cd Chattin
makepkg -csi
Open the app, enter an username and a password, then click "register" to register
Chattin uses rooms to communicate with eachother, you both need to be in the same room to see the messages from eachother.
This is an electron application, which uses e2e encryption to chat with other people.
