Prepost SEO Plagiarism Checker (Alternative)
Explainable overlap highlights + AI rewrites + citation tips. Compare your draft against references you provide—then export a shareable report. Independent tool, not affiliated with PrepostSEO.
Compare your draft against references you provide, highlight overlaps, then generate AI rewrites and citation tips.
Tip: longer drafts make overlap signals more stable.
Example: competitor copy, your previous version, or a source paragraph.
Best-effort extraction. Limit: 3 URLs.
Loose catches more overlaps (more false positives). Strict is safer for exact copying.

Use the checkerCoverage & limitations
Set correct expectations before you rely on the result.
- This is a similarity self-check based on the references you provide—no claim of scanning paid or institutional databases.
- Use overlap highlights to find risky sentences, then rewrite in your own structure and wording.
- If you used a source’s unique idea or wording, cite it (and quote when wording is close).
- URLs are extracted on a best-effort basis; some sites may block automated fetching.
- Do not paste confidential information; export only what you want to keep.
- No guarantees. Treat outputs as guidance, not legal advice.
