Chatwithpdf is a ChatGPT plugin that allows users to semantically search PDF documents using ChatGPT. Users must provide a temporary PDF URL to the tool, from which they can query or analyze the document. Chatwithpdf extracts relevant information from the document and matches queries with processed data to return the most relevant matches. The web-based tool is readily available without installation. The tool does not store any data permanently, and all PDFs are immediately wiped.
