Hello everyone!

I'd like to introduce you a new Codeforces (and AtCoder) tool developed by me and my brother. This tool compares accepted submissions between two users, but with a little twist, you can filter the problem by rating and/or tags. In my opinion, the filter feature is very useful because sometimes we don't want to solve too easy problems that our rival has solved. This tool can be accessed here:

Codes for this tool can be accessed here:

Pull requests, feature requests, or bug reports are welcome. Have a nice day!

Example: I'd like to know which problems Yehezkiel has solved but I haven't and those problems' rating must be between 1900 and 2000, and their tags must include data structures AND binary search.
