I love it. Gonna try and get some of my friends to use this! Plus there's something unabiguously cool about chatting through the terminal... hacker aesthetic or something like that.

How would you say your privacy + tech measure up against Signal and WhisperSystems? I love those folks and what they build and have been using Signal primarily for texting for a while now.

I agree, I wish Signal could work in my terminal somehow in a way that's more secure than their "Desktop" application. They were storing the decryption keys in plain text in a SQLite database iirc. I understand why they have to store it, but it's just bad if it's plaintext.
There signal-cli [1] which works pretty nicely. Uses SMS for initial signup.
