I think you need to sprinkle in some sort of speaking 1-1 with someone instead of chatgpt. That active recall/skill will help not only with speaking but it'll reinforce integration with all your other Korean skills. They'll probably to point out certain nuances/patterns (either culturally or grammatically), that'll probably help you remember language better than an text or AI bot could teach.
Thank you so much for your suggestion. I'll definitely do this once I am more into learning so right now, i only use AI to test me on vocab.
