One-time Windows plagiarism-checking licenses with local processing
Updated August 2, 2026
Plagiarism-detector.com Overview
Plagiarism Detector is a Windows application for checking documents against internet, scientific and local sources. The vendor says checked document text is processed on the user’s PC and is not stored on its servers. Paid desktop editions use one-time licenses; the site also provides a free demo and a separate online AI and plagiarism checker.
Key Features
Pricing
| Offer | Current price | Billing and scope |
|---|---|---|
| Lite | $36 one time | Windows license with internet check, PDF support and two-document comparison |

| Pro | $63 one time | Expanded paid desktop license |
| Portable | $71 one time | Includes USB-drive license capability |
The vendor describes these as one-time licenses with no recurring subscription. A free demo and a separate free online checker are available, but they are not the full paid desktop license.
