Our verdict on PrePostSEO Plagiarism Checker
PrePostSEO Plagiarism Checker is an online plagiarism detection tool for students, teachers, researchers, writers, and bloggers. It compares submitted text with online sources, reports plagiarism and uniqueness percentages, and identifies matched URLs and documents. Users can paste text or upload DOC, DOCX, PDF, and TXT files. The product also supports multilingual checking, citation generation, specific URL exclusions, and rewriting of matched text, making it suitable for individuals who need flexible document and web-content checks across devices.
Its broad platform coverage is a central strength. PrePostSEO is available through the web, Windows, macOS, iOS, Android, and a plagiarism-checking API. Reports can be downloaded in HTML or PDF format, while source exclusions give users control over specific URLs that should not affect a check. The product supports multiple languages and lists 20 language versions, though the available details do not define a plan-specific language count. The API can connect plagiarism checking to websites or other online platforms, but API is the only listed integration.
Pricing follows a freemium model. A free plan is available, while the Monthly plan costs $7 per month and includes 2,500 words per submission, 10,000 submissions, no ads, and no captcha. The Yearly plan costs $5.25 per month with annual billing and includes 2,500 words per submission, 125,000 submissions, no ads, and no captcha. The product is a good fit for mobile users and people who value file-format, language, and platform coverage. Users handling longer checks or requiring academic-source matching should consider alternatives built around those needs.
