The user will find information here about [**the document view**](/en/functions/working-with-a-document/stages/ai-classification/saving.md), tools for navigating pages, saving changes, and switching between the classification and anonymization stages. The operation of [**AI classification**](/en/functions/working-with-a-document/stages/ai-classification.md), verification of automatically detected data, and editing of marked fields. The user will learn how to remove an incorrect marking, change its position, adjust its size, and check the individual categories of detected data. The section also covers the process of [**anonymization**](/en/functions/working-with-a-document/stages/anonymization.md) of the document, including selecting the categories of data to hide, manually adding additional areas, and downloading the finished anonymized version of the file. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://bluurdoc.bluur.ai/en/functions/working-with-a-document.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
