Dialogue is an open-source direct connection chat app. Dialogue doesn't keep user name information or logs and does not communicate with a central server. It is currently a work in progress. I can't recommend using it at all until secure connections are supported, which is the next anticipated feature.
To install Dialogue on Windows or Linux, run the installer executable or extract the files from the Dialogue archive. To install Dialogue on macOS, extract the disk image archive, then mount the disk image. Drag Dialogue.app to your Applications folder. Once the install files are copied, run the Dialogue executable.
If you receive an error indicating a missing msvcp140.dll, vcruntime140.dll, or other DLL files when you run Dialogue, you'll need to install the Visual C++ 2015 Redistributable (x64).
The Visual C++ Redistributable installer is located where you installed Dialogue (default directory for the installer is C:\Program Files\Dialogue). Its file name is vcredist_x64.exe.
Run the Visual C++ Redistributable installer, and you should then be able to start Dialogue.
Enter the IP address of the person you want to chat with, then wait for the Connection Status to change to Connected. Next, select the Conversation button to go to the conversation page. Enter text into the message field and then select the Send button to send your message.
