Turnitin requires institutional licensing. Individual educators, tutors, and freelance instructors can sign up for aidetectors.io directly in seconds.

Frequently Asked Questions
Is aidetectors.io a good replacement for Turnitin?
Yes, for AI content detection specifically, aidetectors.io matches or exceeds Turnitin's capabilities with higher accuracy (95%+ vs ~85-90%), lower false positive rates, and significantly lower cost. Note that Turnitin also offers plagiarism detection, which is a separate feature — if you need both, you may want to pair aidetectors.io with a dedicated plagiarism checker.
Can individual teachers use aidetectors.io without institutional approval?
Absolutely. Unlike Turnitin, which requires institutional licensing, any educator can create a free account and start scanning student work immediately. Our free tier includes 3 scans per day, and Pro plans are available for individuals starting at $9.99/month.
Does aidetectors.io have fewer false positives than Turnitin?
Yes. Independent testing shows Turnitin's AI detector has a false positive rate of 10-15%, with significantly higher rates for ESL/non-native English writers. Our detection engine maintains a false positive rate under 5% across all writer demographics thanks to specific calibration for diverse writing styles.
Can I use aidetectors.io with my LMS (Canvas, Blackboard, Moodle)?
Yes. We offer API integration and plugins that work with popular LMS platforms. While the integration may require some setup compared to Turnitin's built-in LMS connectors, many educators find our Chrome extension or Word plugin to be even faster for checking individual submissions.
Does aidetectors.io detect plagiarism too?
Our primary focus is AI content detection, where we excel. For plagiarism detection, we recommend pairing aidetectors.io with a dedicated plagiarism checker. This combination often costs less than a Turnitin institutional license while providing better AI detection accuracy.

Turnitin has deep institutional relationships and built-in LMS integrations that make it the default choice for many schools.
