Originality.ai

Originality.ai offers text-similarity and AI-writing detection tools that can help editors or writers identify passages that need closer review. Similarity checking can point to overlapping wording, while AI-detection results may prompt a conversation about drafting and disclosure practices.

These outputs are indicators, not definitive judgments. Similarity can arise from correctly quoted material or standard phrasing, and AI detectors can misclassify human-written or edited text. Coverage, settings, and results also depend on the submitted content and the service's current methods.

Review matched passages in context, verify citations, and follow the relevant publisher or institutional policy. Do not treat a percentage or detector label as proof of plagiarism or authorship, and do not use a detector result alone to make a high-stakes decision about a student or researcher.
