How the scanner evaluates your writing

The CASRAI Plagiarism Checker analyzes your text entirely client-side using heuristics designed around standard academic integrity benchmarks. It scans for:

  • Citation Density: Evaluating the frequency and structure of in-text references compared to word volume.
  • Quote Formatting: Checking if direct wording is wrapped in quotation marks to prevent accidental verbatim plagiarism.
  • Sentence Architecture: Finding complex, passive-heavy sentence structures that may indicate mosaic or patchwork writing.
