Checks pasted or uploaded text for web matches with percentage results.

Prepostseo Plagiarism Checker is a browser-based tool for comparing text against online sources and identifying potentially copied passages. It reports unique versus matched content as percentages, points to matching source URLs, and can generate downloadable reports.

Why it stands out

  • Shows both plagiarism and uniqueness percentages at the top of the result.
  • Identifies matched source URLs rather than only giving a single similarity score.
  • Supports excluding a specific webpage, useful for checking content that may already exist on your own site.
  • Makes the word-limit tiers explicit, from free visitor checks to higher premium allowances.
  • Report download options make results easier to archive or share.

Good to know

  • Free unregistered checks are capped at 1,000 words, and free registered checks are capped at 1,500 words.
  • Larger checks, deep search, ad-free use, and higher word limits require premium or enterprise plans.
  • The checker is described as matching against online sources via search engines, so it may not cover every private, paywalled, or offline text database.
