about hashtags

is there any tool that finds duplicate #?
(you add like 20+ # and it checks if any of them is 2+ times.)

any tool or way that helps you find quality hashtags is appreciated.
I am using ig a lot (more from other content than the searching bar) and all-hashtags,
have seen-used some of them: risedecoded, autogramtags, displaypurposes, hashtagify me

Well you can simply add them in excel or similar text tools and delete duplicates. Not really sure how that helps with your second problem but atleast one problem solved
