Want to improve your English while using GPT? Just at the beginning of the dialogue in GPT-4, write
"Please let me know immediately if I make any mistakes in English. If you see any opportunities for me to improve my English (such as making it richer, more professional, or more native-sounding), let me know right away."
And of course, don’t forget about “Act like a X” (for example, "Act like a software engineer in a pair programming session."). In this case, the responses will be more accurate and of higher quality.
