What Turnitin does well
The default AI writing indicator in higher education, embedded in the submission flow most students already use.
Where it falls short
You cannot run it on your own work, and its documented false-positive rate falls hardest on non-native English writers.
The verdict
The tool you are being measured by and cannot access. The honest substitute is a checker that shows you the same signal family and explains it.
Where TextAsMe differs
Every tool above returns a score or a rewrite and stops. TextAsMe marks each sentence, names the signal that fired on it, metronome rhythm, low perplexity, dead metaphor, stock transition, no concrete detail, and rewrites toward a measurement of your own writing rather than a generic human average. The writing analysis and your Style DNA run in your browser, and the text you check for a real AI score is never stored.
