## Direct answer

Run Privacy Scanner or Sanitize for AI in your browser, redact hits, Deep Clean metadata, then copy only the text you need into the AI tool.

## Introduction

AI tools are not a private vault. Sanitize on your device first so you are not pasting payroll, IDs, or client secrets by accident.

## Steps

1. Open Sanitize for AI or Privacy Scanner.
2. Note emails, phones, and ID-like strings.
3. Auto-redact or manually redact as needed.
4. Deep Clean, then export or copy a minimal excerpt for the AI.

## Text export vs full PDF upload

Pasting cleaned text is usually safer than uploading an entire PDF with hidden layers and metadata.

## Limits

- Pattern tools miss some names and formats.
- Scanned PDFs need OCR before text sanitize works.

## FAQ

### Does sanitize upload my PDF?

Not to mypdf — work stays in the browser.

### Safe to upload to AI page?

Yes — /safe-upload-pdf-to-ai is the checklist landing.

### Is this enough for company policy?

Follow your employer’s AI policy; this is a technical hygiene step.
