Plagiarism checker for SEO

Hello community, 👋
I bought a Semrush subscription for some SEO content generation and I discovered a Tool called SEO Writing assistant, It's an all-in-one amazing tool and give also plagiarism detection, and highlights unoriginal texts, Scores of Originality, Readability, and SEO quality.

But sadly, the Plagiarism checker is a separate paid tool and it's so expensive (for the number of articles that I'm trying to write and scan).

Can someone suggest to me the best SEO Plagiarism checker tool that may show useful Data and highlights like Semrush tool please? Thank you, guys
