Short answer

How can I redact and watermark documents with my AI?

You give your AI instructions to find and hide sensitive text or overlay watermarks on specific files. The AI uses the build_document tool to generate a new, secured version of your file. You'll get a finished document that meets your privacy requirements.

The outcomes

Where your files end up

Depending on what you ask, your AI produces one of these results.

SECURED

Redacted files

The AI identifies sensitive info and uses build_document to create a version where that data is completely removed.

PROTECTED

Watermarked files

Your agent applies text or image overlays to the document to mark ownership or status.

REVIEW

Human verification

You check the redacted areas to ensure no sensitive context was accidentally left behind before sharing.

ORIGINAL

Untouched files

If the AI can't find the data you mentioned, it leaves your original document exactly as it was.

The workflow

What your AI does when the request arrives.

The AI handles the heavy lifting of document manipulation through a single specialized tool.

  1. Analyze the file

    Your agent reads the document to locate the specific text, names, or patterns you want to hide.

    build_document

  2. Apply security layers

    The AI prepares the redaction masks or watermark placements based on your specific instructions.

    build_document

  3. Generate the new file

    The AI executes the changes by building a fresh, modified version of the document.

    build_document

  4. Deliver the output

    The process finishes once the new file is ready for you to download or view.
