Latest AI Detector Guides
Every guide grows out of our August 2026 test round, where we tried to run a 12-sample set through the free scanners teachers use most and published exactly what happened. New guides land each school term, on the same schedule as our retesting.

Can AI Detectors Detect Paraphrasing? We Ran the Experiment
We hand-rewrote an AI essay the way a motivated student would and ran it through real detectors. Pangram caught the rewrite at 100% confidence, then flagged all three human-written essays as 100% AI in the same session.

How We Write These Guides
Every claim carries a source label: hands-on results come from our published test archive, vendor capabilities from official documentation, independent findings from named research. When we could not test something ourselves, the guide says so in the same sentence as the claim. And when a guide uncovers a free-tier limit or a false-positive pattern, the corresponding review page gets the same correction in the same retest cycle.
Frequently Asked Questions
What does the TeacherDetect blog cover?
Practical AI detector guides for classrooms: what to do when honest work gets flagged, how to design assignments that resist chatbot shortcuts, and how detection tools work under the hood. Every post links back to our tested detector rankings.
Where does the data come from?
From our August 2026 test round (12 samples run through free detector web scanners), official vendor documentation, and named third-party research and reviews. Each article labels which source backs which claim, and we never present documentation as hands-on results.
How often are guides updated?
We retest detectors each school term and update the guides on the same schedule, because vendors retrain their models and change their free tiers constantly. Articles carry their publication date, and test-related claims name the round they came from. Suggestions for future AI detector guides are welcome through the contact page.
Editor's note
Every guide here ends at the same purchasing question. Our tested recommendation for teachers, Originality.ai, covers AI detection and plagiarism in one report, and its scan history documents every verdict for the conversations that matter.
