I wrote an IDA plugin that queries #ChatGPT and explains decompiled functions. It's still very bleeding edge, but you can find the code here and try it out:

(Yes, the video was performed on a very basic case for simplicity's sake.)

This is a follow-up of the last few days' experiments: https://infosec.exchange/@justicerage/109443985246830894

I'm still figuring out exactly how much we can do here. There may be a way do do a decompilation plugin too, but it will require more work to integrate with IDA. I'll post more as I discover more!
