How does Сhat with PDF work?

Upon uploading a file, Chat PDF analyzes its contents, essentially reading it within seconds. It then automatically generates three prompt questions, offering you a starting point for exploring the file. Additionally, you have the option to ask Chat PDF your own questions about the text, enabling you to quickly access specific information without having to read through the file yourself.

How to make Chat read a PDF?

After you upload your file, the tool instantly starts reading through the whole document. You can then ask your PDF about a specific section within the file, enabling you to uncover detailed insights.

How to summarize a PDF with Chat PDF?

You can easily use our tool as a PDF summarizer. Once you've uploaded your document, simply ask the chat to recap its contents. You can ask, "Summarize it," or request the key points. The more precisely you articulate your needs, the more accurate the results will be.

Does Chat PDF understand other languages except English?
