What Smodin Plagiarism Checker is
Smodin Plagiarism Checker compares submitted text with web and academic material, then returns similarity scores, matched source links, and highlighted sections for review. Users can paste text or upload .txt, .doc, .docx, or .pdf files; a scan requires at least 1,000 characters. Smodin says the checker scans more than 1 billion sources and uses keyword and phrase matching against online pages, as well as comparisons with submitted documents. The resulting report helps readers locate matching passages and sources to review and cite. The checker is browser-based, and Smodin also lists Android, iOS, web, and extension availability, plus a plagiarism and auto-citation API. The API is available in 12 languages and uses pay-as-you-go pricing. A free plan is available. The Starter plan costs $10 a month billed annually, while Premium is $16 a month billed annually and includes advanced scans and a Chrome extension. Smodin lists email and phone support, and users may request personal-information deletion through account settings or support.
