What both publish
| Fact | Check-Plagiarism | Copyscape |
|---|---|---|
| Licence | The opened vendor pages describe a hosted commercial service and do not state an open-source licence. | The terms reserve copyright in the service and restrict copying and access to authorized users, so Copyscape is proprietary rather than open source. |

| Purpose | The service checks text for plagiarism and reports duplicated sections, similarity percentages, and matching sources. | Copyscape checks web content and new human- or AI-generated content for plagiarism and duplicate text found online. |
