About this review

EssayDetector reviews language patterns with a hosted model and a transparent deterministic fallback, always labeling which method ran. Results are probabilistic review cues, never proof of authorship, and submitted text is never stored. Maintained by the EssayDetector team; page last updated 2026-08-12.
