I Googled "applescript loop through apple notes" and this was the first result: https://apple.stackexchange.com/questions/225938/notes-scrip.... Looks exactly like what ChatGPT came up with for you minus the dialog.

I then Googled "applescript print to console" and got this: https://stackoverflow.com/questions/13653358/how-to-log-obje... ; admittedly this answer took a few minutes to read through, but the second most upvoted answer recommended using log, which your ChatGPT-developed solution (eventually) used.

This all took me < 5 minutes.
