What Is ChatPDF & How Can You Use It?

What is it?

ChatPDF lets you talk to any PDF document as if it were a person who read the entire file. You upload a 50-page paper, and you can ask it "What does section 3 mean?" or "What are the main findings?", and it answers immediately with the exact page numbers.

What can I create with it?

You can create textbook study summaries, contract risk assessments, financial report summaries, and literature reviews.

What makes it different?

Every answer includes clickable page citation pills that highlight the exact paragraph where the answer was found.
