Even as a tool it lacks predictability / reproducability. If I give instructions to download a paint program, start a new canvas of 1920x1080 and use the gradient tool to go from red to green, you’re going to get the same result every time. If I instead told a class of students to ask an AI to generate a red to green gradient on a 1920x1080 canvas, the results would not be consistent.

I use AI, but it is a tool with flaws.

Do note, because it’s using email, the recipient and sender are not private, along with the time, and probably the relative size of the messages.

The specific content of each message should be private as long as the encryption is done well. I haven’t looked at it so I don’t know if it implemnts safeguards to verify who you’re messaging with (besides using the email address) and I don’t know if it uses PFS (Perfect Forward Secrecy) to protect against a key getting compromised.
