Understanding Plagiarism Scores

Our originality scoring system categorizes results as follows:

  • 90-100% Original: Excellent - Content shows high originality with minimal matches. Suitable for academic and professional use.
  • 70-89% Original: Good - Some matching content detected. Review highlighted sections and add proper citations where needed.
  • Below 70% Original: Needs Improvement - Significant plagiarism detected. Major rewriting and proper citation required.

Best Practices for Avoiding Plagiarism

  • Always Cite Sources: When using someone else's ideas, data, or direct quotes, provide proper citations following your required style guide (APA, MLA, Chicago, etc.).
  • Paraphrase Properly: When paraphrasing, substantially rephrase the original text and still cite the source. Changing a few words is not sufficient.
  • Use Quotation Marks: For direct quotes, use quotation marks and provide exact page numbers in your citation.
  • Develop Original Ideas: Build upon existing research with your own analysis, interpretations, and conclusions.
  • Keep Track of Sources: Maintain organized notes and references throughout your research process to avoid accidental plagiarism.
  • Use Plagiarism Checkers: Regularly check your work with tools like this one before final submission.
