Double cards

Hi!

I use Kitsun as a dictionary when I read, and I usually add most of the words I look up to a deck.
Every now and then, though, I forget I’ve already added a word and end up with duplicates.

Is there any easy way to detect or flag duplicate cards?
I tried sorting by meaning and other fields, but with hundreds of words it’s almost impossible to catch them all.

Thanks in advance!

One could filter cards by ‘known’ and ‘0’ level; assuming you already have the originals in review, one can hibernate or delete those cards. Doing this every so often should filter out the duplicates.
