About DrillBit and your file

Checks are run on DrillBit, an Indian plagiarism and AI-detection service, and you receive DrillBit’s own report. To run a check, your PDF is uploaded to DrillBit and handled under DrillBit’s terms and privacy policy. Those terms allow DrillBit to keep uploaded documents for archiving and further use, though its website also says documents are not permanently stored. If your work must not be stored outside your university, please talk to us before uploading.
