Vanderbilt ran the arithmetic in August 2023. Turnitin claimed a 1% false-positive rate, and Vanderbilt processed roughly 75,000 submissions a year. That is 750 wrongly flagged papers a year, so the university switched the detector off. Which is why the best AI detectors for essays are not the ones with the loudest accuracy claim. They…

You cannot buy Turnitin. There is no individual plan, no free student sign-up, no way to run your own essay through the exact tool your school uses before you submit it.

Fifteen percent of essay submissions now contain more than 80% AI-generated writing. That figure, pulled from Turnitin’s own data, is up five times from just 3% when the company launched its AI detector in April 2023.

Yet when researcher Mike Perkins evaluated 14 AI-detection tools, not one scored above 80% accuracy. So where does that leave you? Searching for the best AI detectors for teachers that actually work…
