| Name | CheckforAi |
| Overview | CheckforAi was a text-analysis tool for reviewing essays and emails for possible AI-generated content. Its official website now says the service has been sunset; the features below describe its former purpose. Its retained disclaimer describes proprietary and existing AI models trained for English text, with probabilistic risk scores rather than guaranteed accuracy. Human-written text can be flagged, and file checks sometimes covered only part of a document. Its intended review topics included SEO content, academic integrity and personal or business communications. A detector score cannot by itself prove plagiarism, authorship or email identity, and the provider warned against decisions based solely on scores. Google’s guidance emphasizes content quality and value, not protection from penalties through an AI detector. The former listing included Twitter and Substack channels; the sunset page links to Substack for updates on other projects, not an active detector service. |
