Plagiarism detectors are software tools designed to identify instances of copied or closely paraphrased content in written work. They compare submitted texts against a vast database of sources, including academic papers, websites, and books, to find similarities. This helps ensure originality and academic integrity in various fields, including education and publishing. These tools are commonly used by educators, students, and professionals to check for plagiarism before submitting work. By highlighting potential issues, plagiarism detectors encourage proper citation practices and help users improve their writing skills while respecting the intellectual property of others.
