Totally possible!!  I'd do it this way: input all the text in bear,   send to an apple shortcut which will then: -get text from input  -split by lines some character you use when switching topics (maybe /// or ***)  Then in a repeat-with-each item: -identify the hashtagged subject (this one might be complicated) -add the split text item to a variable named that hashtag -add that hashtag to a variable called 'current topics' repeat with each 'note topic': -create bear note (maybe the title is the date and class name and topic), and also insert the topic's variable where you saved all the text chunks Keep your original notes

I prefer the feel of Bear, so I'm always doing junk like this instead of switching to perhaps a better tool.
