Modern technology has all but eradicated the need for plagiarism checkers these days. That is because the tech savvy students use Ai to write their papers, which automatically return links for the sources used in the development of the topic. Since these links exist, it becomes easier for the students to avoid plagiarism because:
1. The students can easily verify the information sources;
2. The students can easily write an original paper for themselves based on the model and use the links that were previously used to develop the paper.
3. They can easily reformat the cited information within the paper for the writing style that is required for the class.
So plagiarism checkers do currently still exist, but AI has made it difficult for them to stay in business already.
