Frequently asked questions

Does it work on scanned PDFs?

Yes — image-only pages go through OCR first, then the same citation-backed summarization as a text PDF.

How long can the PDF be?

The free trial handles a few pages without signing up. A free account raises that limit; Pro removes it.

Can I ask questions about the PDF afterward?

Yes — every PDF gets its own chat, answered from the PDF's actual text with citations, not a generic model reply.
