Tips for the best result
- Chat with PDF reads the text of your PDF. If it says there is no text, the PDF is a scan: make it searchable with OCR PDF first.
- Long documents: about the first 25 pages of text are used. Split a longer PDF and use each part.
- Check names, amounts and dates in the PDF itself before relying on them. AI is fast, but it can be wrong.
- Answers and summaries can be copied, or saved as a Word file to edit and share.
- Don’t use AI tools for confidential documents; the AI service may keep what it receives under its own terms.
