Frequently Asked Questions
How does PlagiarismGuard detect plagiarism?
We use vector embeddings and text similarity algorithms to compare submissions against indexed web content and your historical submission database, surfacing matches even when text is paraphrased.
What file formats are supported?
You can upload PDF, DOCX, and plain text (.txt) files. Bulk ZIP uploads are also supported so you can check an entire class at once.
Is student data kept private?
Yes. Submissions are encrypted in transit and at rest, never shared with third parties, and automatically deleted after 90 days unless you choose to retain them.
