Ensemble of stylometry + two fine-tuned DeBERTa models, scored in ~300-word windows, with a per-sentence heat map for mixed authorship.

Results on the Chicago Booth benchmark (1% false positives): plain AI 99.7%, after a StealthGPT humanizer 85%. On generators the models never saw (889 texts): 92.6% flagged. Weak spots published too: TOEFL exam essays 8.8% false positives (1.1% in precise mode), humanizers, short texts.

I’m looking for adversarial and non-native-writer texts to break it. DM me if you want a hosted demo with file upload.
