NoPlagio

O que é NoPlagio?

NoPlagio is an online text-review service for students, educators and writers. It checks documents for overlap with public web material and academic sources, and offers a separate detector that estimates whether text may have been generated by AI.

A plagiarism report highlights matching passages, links to sources and marks paraphrases and citation issues. The AI detector gives a document-level probability score and flags likely sentences. Use these results to review a draft and its sources; they are signals for human review, not an academic integrity decision.

Similarity and risk signals help locate text for closer review. Color marks distinguish paraphrases, incorrect citations and correctly quoted text, and source links let you inspect each match.

Screen for likely AI-generated writing

The AI detector provides a probability score for the full document and flags sentences it considers likely AI-generated. It supports more than 50 languages and offers a downloadable PDF report.

Students can inspect matched passages and source links in a thesis, essay or project paper, then review citations and paraphrases before submitting it.
