ChatWithPDF

ChatWithPDF is a ChatGPT plugin that enables users to query and semantically search PDF documents directly within ChatGPT conversations. Users provide a publicly accessible PDF URL, which the plugin processes and analyzes. The plugin then matches user queries against the PDF content and returns the most relevant matches, making it useful for students, researchers, and professionals who need to extract information from documents without leaving the ChatGPT interface. The tool supports PDFs of any size, language, topic, and length. Installation requires GPT-4 access through the ChatGPT Pro subscription, where users can add it from the Plugin Store. One notable limitation is that the tool requires PDFs to be publicly accessible via URL, which may not be suitable for private or sensitive documents. The plugin prioritizes privacy by not permanently storing PDFs—embeddings are typically purged every 12-24 hours due to vector database constraints.
