In their own words
SmallSEOTools Plagiarism Checker
SmallSEOTools Plagiarism Checker compares submitted text with online sources and returns a report identifying matches. Users can paste text, upload files from local or cloud storage, or check a URL. Upload formats include.doc,.docx,.txt,.tex,.rtf,.odt, and.pdf. Reports show duplication scores, exact and partial matches, flagged sentences, and source URLs. Quotations, references, and other properly attributed material can be excluded from the similarity score. The checker says it detects paraphrased content and synonym replacements as well as exact matches, and supports checks in more than 25 languages. Reports can be downloaded in PDF or Word format. The free plan allows up to 1,000 words per scan; paid plans start at $9.80/mo. An API is documented for plagiarism checks and account status, and a WordPress plugin checks content from the dashboard after an API is added in its settings. The product page says submissions are processed through a secure connection and remain confidential after analysis.
