You can absolutely submit screenshots of text conversations as evidence in court. I’ve literally done this myself.
Someone could challenge the veracity of the evidence if they wanted to, at which point you might want to prove that they hadn’t been edited by doing something like showing the copies that are actually on your phone. But you can absolutely submit screenshots.
So… if Duolingo is just AI now, why would anyone pay for Duolingo? Just ask the AI for language lessons yourself.
