Is Chegg Plagiarism Checker Accurate?

While Chegg’s plagiarism checker is a useful tool, its accuracy is not as comprehensive as Turnitin or Copyscape. Let’s explore its accuracy in different areas:
1. Database Coverage
✅ Chegg scans a large number of web sources, including articles, books, and academic journals.
❌ It does not have access to private university databases, meaning it won’t detect matches with student-submitted papers in Turnitin or SafeAssign.
2. AI Detection Capabilities
✅ Chegg uses AI-powered plagiarism detection to highlight paraphrased or similar content.
❌ It may not detect AI-generated content effectively, making it less reliable compared to AI detection tools like Turnitin’s AI Detector.
3. False Positives & Missed Matches
✅ Chegg is good for catching direct copy-paste plagiarism from public sources.
❌ It sometimes produces false positives, flagging common phrases or cited content incorrectly.
❌ It may miss reworded or paraphrased plagiarism, unlike Turnitin, which has an advanced paraphrase detection system.
4. Speed and Report Accuracy
✅ Fast scanning – Chegg provides plagiarism results within minutes.
❌ Lacks detailed analysis – Unlike Turnitin, Chegg does not offer a detailed originality score or a side-by-side comparison of sources.
