What is the word limit to check plagiarism?

When checking for plagiarism, there is no specific word limit. This means you can check any amount of text, regardless of length. However, some plagiarism detection services may restrict the maximum number of words that can be checked simultaneously.

Are free plagiarism checkers efficient enough?

Free plagiarism checkers are a great way to ensure that your content is original and free of copied material. However, these tools are efficient enough to detect any similarities between your work and others, which can help you identify and address any issues before they become a problem.

However, these tools may only detect some forms of plagiarism, such as using quotes or paraphrasing without proper attribution.
