AISEO Plagiarism Checker
ChatGPT pluginCheck text and review sources
Check a passage against published sources with AISEO. Review the returned plagiarism score, uniqueness score, matching sources, and matched sentences.
Use the results to inspect overlap and decide where quotations, citations, or revisions need attention. Similarity scores are indicators. They do not prove plagiarism, establish authorship, or guarantee that a passage is original.
Paste between 40 and 10,000 words for each check. An AISEO account and sign-in are required. Results depend on source coverage and your account's available allowances. The plugin checks supplied text; it does not publish your work.
