Happy to help! To give some context: there was a GPT prompt which was something like "Act as a language tutor. I'll have a conversation with you, and you reply back. If I make a grammar mistake, keep the conversation going, but put the correction in a parenthetical statement."
I was using that for a bit, but typing in another language was enough friction (vs. speaking) that I didn't use it that much.
For this, audio is perfect -- all I need is the gentle reminders about what to fix, and why. GPT could probably have a parenthetical part in the official transcript too.
Anyway, hope that helps give context.
