SmallSEOTools Plagiarism Checker
Verified working Sep 22, 2026
Checks writing for reused passages and points to matching sources.
SmallSEOTools Plagiarism Checker is a web-based originality scanner for essays, articles, assignments, and other written work. Users can paste text, upload common document formats, or scan a URL, then review similarity scores, matched source links, and sentence-level flags.
Why it stands out
- Supports several input paths, including pasted text, document upload, cloud/local files, and URL-based checking
- Breaks results into exact and partial matches instead of showing only one similarity number
- Can include or exclude specified URLs before scanning, useful for checking against a known source page
- Report exports in PDF or Word make results easier to hand off outside the tool
- Language selector covers 25+ languages, broader than many simple plagiarism checkers
Good to know
- The visible free checker shows a 1,000-word input limit
- No-word-limit scans, API access, user seats, and ad-free use appear to require a paid plan
- URL exclusions are capped at 10 entries
- Similarity results still need human review, especially for quotations, citations, and common phrasing

Technical Notes
- Paid options mention access to a Plagiarism API, but the extracted page does not show endpoint, authentication, or rate-limit details.
