| AI detection | The detector provides sentence-level analysis, confidence scores, and an overall AI probability for text associated with major language models. | The service estimates whether text resembles writing generated by systems such as GPT, Claude and ChatGPT. |
| API | The API is a REST interface that returns overall AI probability and can provide sentence-level scores. | The public REST API accepts scan requests and returns AI-likelihood and plagiarism results; the help page says it supports 30 languages. |
| Browser extension | The Chrome extension lets users select text on webpages for AI detection and displays sentence-level results. | The extension scans Google Docs, web pages, or selected text and includes writing replay, typing behavior insights, and shareable reports. |
| Integrations | The vendor lists a Chrome extension, a Microsoft Word plugin, and an API as integrations; it says there are no LMS integrations at the moment. | Originality.ai offers a Moodle integration for reviewing submitted work for AI-generated text and plagiarism within Moodle. |
