About PDF.ai

PDF.ai is a cloud tool for chatting with PDF documents conversationally—asking questions, summarizing, and pulling out answers with precise citations back to the source, plus an AI parser that converts PDFs to structured markdown or JSON. It's aimed at researchers, students, and business teams who work through long or multiple documents, as well as developers who need a PDF-parsing API. Its main differentiator is combining ChatGPT-style multi-document chat with source-linked citations and a developer-friendly extraction API in one product.
