PaperCheck gives estimates from AI-text detectors and a plagiarism comparison against arXiv papers. Results can be wrong and are not a decision about whether anyone used AI or plagiarised.
PaperCheck is not affiliated with Turnitin or any university.
Only upload documents you have the right to submit. You remain responsible for your work and for following your institution's rules.
Free limits apply per person. Creating several accounts to get more free words is not allowed and leads to the loss of free access.
We may change or stop the service at any time.
