SmallSEOTools Plagiarism Checker
London, UK
What it is
SmallSEOTools Plagiarism Checker compares submitted writing with online sources and returns a report showing matches. Users can paste text, upload files from local or cloud storage, or check a URL. Supported file types include .doc, .docx, .txt, .tex, .rtf, .odt, and .pdf. Reports include duplication scores, exact and partial matches, flagged sentences, and matched-source URLs. Quotations, references, and other properly attributed text can be excluded from the similarity score. The checker says it detects paraphrased content and synonym substitutions as well as exact matches, and supports checks in 25+ languages. Reports can be downloaded in PDF or Word format. The free plan allows up to 1,000 words per scan. The Monthly plan is $9.80 a month, and the Yearly plan is $94.08 a year; both list a 30k-word limit, WordPress plugin, and API. The documented API is for plagiarism checks and account status, while the WordPress plugin checks dashboard content after API setup. The product page says submissions are processed through a secure connection and remain confidential after analysis.
