Frequently Asked Questions

Why does ChatPDF limit free users to 2 PDFs per day?

ChatPDF processes documents on their servers via OpenAI API calls — real costs per document. Our browser model eliminates this.

Does ChatPDF support 200+ page documents?

ChatPDF free caps at 50 pages; paid plan supports more. PDF AI Tools has no page limit.

Does PDF AI Tools upload documents to OpenAI for Q&A?

Only the text you ask about is sent to the AI model; no document is stored permanently.

Can I use PDF AI Tools just for ChatPDF-style Q&A?

Yes — open a document and start chatting; other tools are there when you need them.
