ScanMyEssay Plagiarism Checker & AI Detector
Pay-as-you-go plagiarism and AI content detection for academic integrity
Updated August 1, 2026
ScanMyEssay Plagiarism Checker & AI Detector Overview
Viper Plagiarism Checker & AI Detector is the current product sold on the ScanMyEssay domain. It scans uploaded work against essays, journals, internet sources and known AI-generated content, then returns an originality report through a three-step upload, scan and report workflow.
Viper uses pay-as-you-go GBP credit bundles rather than a subscription. Scans are confidential by default, but users can choose repository scanning, so uploaded work should not be described as unconditionally excluded from every repository.

Pros
| Comparison | Where Viper may fit better |
|---|---|
| Turnitin | Viper has public pay-as-you-go credit bundles for individuals without asserting that it is universally cheaper. |
| Scribbr | Credits can be purchased only when a document needs checking. |
| Quetext | The same credit model covers plagiarism and AI-content detection. |
| Copyleaks | Viper avoids a recurring monthly subscription for occasional use. |
| PlagiarismCheck.org | Large bundles lower the GBP price per credit for high-volume scanning. |
Cons
| Comparison | Tradeoffs to check |
|---|---|
| Turnitin | Institutions should compare repository, LMS and governance requirements rather than assume equivalent coverage. |
| Scribbr | Pricing is in GBP and is based on credits and words, not a flat report fee. |
| Quetext | There is no permanent free plan or trial listed on the current price page. |
| Copyleaks | Bulk thresholds are described inconsistently on the official page, so custom volume requires sales confirmation. |
| PlagiarismCheck.org | Users who prefer a recurring monthly allowance may find the credit model less predictable. |
