Pros

Competitor

Pros
Turnitin ScanMyEssay is far more accessible for individual users, offering transparent pay-as-you-go pricing instead of institutional contracts. It is easier to use without academic enrollment and provides quick scans without complex onboarding, making it practical for freelancers, students, and independent researchers.
Grammarly Compared to Grammarly, ScanMyEssay focuses more deeply on plagiarism and AI detection rather than general writing assistance. Its reports are clearer for academic integrity checks, and users do not need an ongoing subscription just to run occasional originality scans.
Quetext ScanMyEssay offers a simpler pricing structure with granular credit control, which can be more cost-effective for large documents. Its AI detection is bundled directly with plagiarism checks, avoiding separate feature tiers that can complicate usage.
Copyscape Unlike Copyscape’s web-focused plagiarism checks, ScanMyEssay is designed for full document uploads, making it more suitable for essays and dissertations. It also includes AI-generated text detection, which Copyscape does not natively provide.
Scribbr ScanMyEssay is generally more affordable for repeated scans and does not lock advanced checks behind premium academic services. Its faster turnaround and flexible credit bundles suit users who need frequent checks without editorial add-ons.

Cons

Competitor

Cons
Turnitin Compared to Turnitin, ScanMyEssay may be less authoritative in institutional settings where Turnitin’s proprietary databases are required. Some universities may not officially recognize ScanMyEssay reports for formal submission or misconduct investigations.
Grammarly ScanMyEssay lacks advanced writing feedback such as grammar correction, tone suggestions, and style improvements that Grammarly provides. Users seeking an all-in-one writing assistant may need to pair it with another tool.
Quetext Quetext offers a more modern interface and citation assistance features, which ScanMyEssay does not emphasize. Some users may find ScanMyEssay’s UI more functional than polished.
Copyscape Copyscape is faster for checking short web content, while ScanMyEssay is optimized for longer documents. For marketers checking multiple URLs quickly, ScanMyEssay may feel slower and less streamlined.
Scribbr Scribbr integrates premium academic editing and direct Turnitin-powered checks, which ScanMyEssay does not include. Users needing formal proofreading and citation correction alongside plagiarism checks may find ScanMyEssay limited.
