How does PDF chat work?
Your PDF is uploaded to our secure server, text is extracted from each page, and processed by our AI engine. You can then ask unlimited questions within your session. The AI reads the entire document and answers based solely on its content.
Your files stay private
Your PDF is processed on our secure server and permanently deleted after your session ends. Extracted text is only used to answer your questions and is never stored, shared, or used for AI training.
