In Help - Settings, there is an option called Enable PDFgear Copilot. You can deselect that option to turn off the AI feature.
Please note that your document won't be analyzed automatically even when Copilot is enabled. The content is only processed when you start to use AI chat with PDF. The AI does not directly read your text. Instead, it processes the document by mapping all content into coordinates.
