On a - slightly humoristic but serious - side note:

Your use-case seems to match pretty much the niche called "plagiarism checker"

(very popular in Germany since some politicians with cheat PhDs had to resign.)

You might find more solutions there.

And on another side note:

A "challenge" is a programing competition where the author already has a solution and wants to entertain the gamers in a competition.

Please don't call it a challenge if you don't know what to expect and just want your problem to be solved for free. :)
