ChatPDF

Documents like contracts, manuals, essays and research papers are where ChatPDF earns its keep. ChatPDF is an AI PDF summarizer and question answering tool that extracts the text from a PDF, passes it to GPT, and lets you ask about the file in plain language.

Each answer comes with cited sources, so you can check a claim against the part of the document it came from instead of trusting it blindly.

ChatPDF works in any language, which helps when your document and your questions are in different ones.

Summaries and answers are free.

It is also listed as an AI API, so developers may find a use for it alongside students and office workers who just want a faster way through a long PDF.
