Verdict
What is ChatPDF?
ChatPDF answers questions about a PDF you upload, pointing back to where in the document the answer came from.
What it does well
The single-document question: what does this contract say about termination, what does this report conclude, where is the figure I need.
Who should use it
Students, and professionals who occasionally need to interrogate a long document.
Who should not use it
Anyone handling confidential client or commercial material without first checking the data terms — and anyone doing this daily, who would be better served by a general assistant with a document workspace.
