The last few days, I’ve been using TurnItIn to check my Metro students’ research papers for plagiarism. The college pays for the service, and I started wondering what free online services are available for detecting plagiarism. I even asked about that on Twitter but received no responses, so I did some research. Here are the ones I found:
- PlagiarismDetect.com – requires registration
- DOC Cop – requires registration
- Glatt Plagiarism Self-Detection Program
- Dupli Checker
- The Plagiarism Checker
- Article Checker
- Plagium – in beta
- CopyTracker Online – in beta
- crossrefme.net – in alpha
I haven’t tried any of these, and I’d be very interested in finding out how they worked for you.
