| Problem it solves | Gives students, researchers, writers and businesses a quick, pay-per-check way to see whether a document shows AI-writing signals or closely matches existing sources, without a subscription. | Rewording, condensing or checking text by hand is slow, especially for students and non-native writers. |

| Developer API | No | No |
| Open source | No | No |
| Platforms | Web | Web, Browser extension, Microsoft Word, Google Docs |
