I wish there was a duplicate word statistics feature

I've mentioned this before, but it would be nice to be able to see duplicate words as statistics at a glance in conjunction with the current AI feature.

It would be even more useful if it could be set to nouns, adjectives, etc. For example, pretty / pretty / pretty, even if it is used in various ways, could it be lumped together as a duplicate expression?

If this is possible, I think it would make it easier for me to invest a little bit of retrospective time and add a little more variety to a post that might otherwise be bland with redundant expressions.
