| Integrations | The MCP server can be used with Claude Desktop, Claude Code, or another MCP client. | Basic and Unlimited plans list Microsoft Word and Google Docs plugins. |

In their own words
AI Detector Pro
AI Detector Pro is a web product for identifying signs of AI in documents and revising or humanizing text. For English documents, it highlights passages likely to trigger AI detectors and shows predicted text and overused AI phrases. Detection is listed for English, Spanish, French, Arabic, German, Korean, and Portuguese writing. AI Eraser suggests English wording changes, with a choice about how much to revise. Other tools include tone analysis, phraseology, and a pinpoint editor. The Free plan includes three AI scans per month and no humanizations. Basic allows 103 scans per month, while Unlimited provides unlimited scans; both list unlimited humanizations, multilingual detection, the editor and tone analysis, as well as Word and Google Docs plugins. API access requires an eligible subscription: report requests cost $0.09 per unit of up to 4,000 characters, and other endpoints are free. The company says user text may be shared with third-party AI models for core functionality. User content is automatically deleted at the beginning of the fourth month after entry, while documents created with the product remain until the user deletes them or the account is deleted. The site cautions that model randomness can lead to incorrect identifications or humanizations.
