Instagram unique/same follower on different accounts, tool?

Hi,

i have a few instagram-pages in the same niche. Did there exist a tool with that i can analyse all accounts together, to see how many unique follower i have?

For example i have two accounts with each 1000 follower, but 100 hundred are following both accounts, so i have only 1900 unique follower.

Did anyone know a tool like this?

Thank you very much

I don't know a tool exactly, but it can be done with iMacros.
Firstly, scrape the usernames of your followers on different accounts and then use excel functions to find/remove duplicates etc.

Hope it helps if you don't find a bot/site that does as you mentioned.

hmm...never saw any tools like this..scraping both account users...then matching and then deleting them...
