Text checks accept up to 5,000 words at a time. - Image scanning runs entirely in the visitor's browser; images are never uploaded. - Text is scored with zero retention and is never used for model training. - Scores are probabilistic, not proof of authorship. Detection over-flags writing by non-native English speakers, short passages, and formal or templated genres, and it is defeated by paraphrasing. Do not present a score as evidence of misconduct.
