Tor Messenger is a cross-platform chat program that aims to be secure by default and sends all of its traffic over Tor. It supports a wide variety of transport networks, including XMPP, IRC, Twitter, and others; enables Off-the-Record (OTR) Messaging automatically; has an easy-to-use graphical user interface; and a secure automatic updater.
See the introductory blog post for more information.
Please note that Tor Messenger is still in beta. The purpose of this release is to help test the application and provide feedback. At-risk users should not be depending on it for their privacy and safety.
The current version of Tor Messenger is v0.4.0b1, released on March 6, 2017.

See this matrix to determine where the profile folder is stored on your platform.
Note that as a policy, unencrypted one-to-one conversations are not allowed and your messages will not be transmitted if the person you are talking with does not have an OTR-enabled client. You can disable this option in the preferences to allow unencrypted communication but doing so is not recommended.
We are doing automated builds of Tor Messenger for all platforms.
The Linux builds are reproducible: anyone who builds Tor Messenger for Linux should have byte-for-byte identical binaries compared with other builds from a given source. You can build it yourself and let us know if you encounter any problems or cannot match our build. The Windows and OS X builds are not completely reproducible yet but we are working on it.
