What is Tor Messenger? Anchor link
Tor Messenger is an instant messaging client that sends messages over the Tor anonymity network. It is available for Linux, macOS, and Windows. Tor Messenger supports a variety of messaging networks and protocols including IRC, XMPP, Twitter, Google Talk, and others. In addition, off-the-record encryption is built in.
In its default configuration, Tor Messenger only communicates via the encrypted off-the-record (OTR) protocol. This means that if you want to talk with someone who doesn't have a program capable of chatting over OTR, you won't be able to communicate with them. You can change this option by going into “Tools -> OTR Preferences” and unchecking “Require encryption,” but keep in mind this will send your conversations over plaintext so your instant messaging provider can see the message contents.
Tor Messenger is still in beta, which means that it may have reliability or functionality shortcomings. Use with caution.
