FAQ
How does OriginCheck detect AI-generated text?
It measures sentence entropy, vocabulary diversity, burstiness, and perplexity patterns that differ between human and AI writers, then combines them into a single confidence score.
What file formats are supported?
You can upload PDF, DOCX, and plain-text (.txt) files. Minimum 150 words are required for a reliable analysis.
Is my students' data kept private?
Uploaded documents are analyzed in memory and never stored on our servers. No assignment content is retained after the report is generated.
