Hello troupers !
Many times I need to give fewer amount of important keywords (like on Alamy). Is there any quick way of doing it. DeepMeta can remove a few duplicated, Shutterstock suggestion tool do it also, but only 5 or 6 in a batch of 50.

Is there any brighter program or tool that can do "human'ish" job to help ?

Probably the easiest way is to deal with them in Excel. Search for a particular keyword and bulk delete it. I often use "people, person, man, men" etc. Get rid of men and people. In a large group you may be  deleting several hundred words at a go.

I get the idea, but actually, I use "people" only when there is many people and I use "person" when there is only one person. I don't use both at the same time so I might delete important stuff.

I'm thinking about converting my description into a list of keywords, but some important stuff will be missing.
I don't know... have no easy solution.

my solution for now is to use only the words in the description or title of my file. Then ... I'm working on titles that use the best keywords and it's easy to copy / paste the tile to get only 5 or 6 great keywords.
