Text sent through the connector is handled like any other check. The scan and its result are saved to your account history. We do not sell this data, use it for advertising, or use it to train AI models, and the connector does not show ads. The assistant you use is a separate service with its own privacy policy. Read Section 7 of our privacy policy for details, or contact us for help.

Is the connector free?

The connector has no separate cost. Each check uses words from your account, the same as a check on our site. A free account includes 3,000 words a month. Running both checks on a text uses its word count twice.

What happens when I run out of words?

Does an AI score prove that someone used AI?

Will the result match Turnitin?

How do I unlink it or delete my data?
