I use ChatGPT's conversation mode to supplement my language learning (A2/B1-ish French and 1hr/wk 1-on-1 tutor). I tend to use it in the car, just asking about random facts or ideas or playing 20-questions.

The format forces me to just use my voice and listening skills - in other words, I'm forced to not touch my phone. It's also rather challenging because I'm doing two things at once and the hope is that I won't actually spend much brain power overthinking my responses - something I tend to do if I was talking to myself instead which typically turns into more of a rehearsal format.
