| Description | ChatPDF is an AI document assistant that lets you upload PDFs (plus Word, PowerPoint, Markdown, and text files) and ask questions in natural language, returning answers linked back to specific pages so you can verify sources. It's aimed at students turning readings into study notes and at analysts, researchers, and consultants skimming long reports for key takeaways. Its main differentiator is being one of the earliest, simplest ChatGPT-style PDF chat tools, with cited page references and no account required to start. | Perplexity AI is a conversational answer engine that searches the web in real-time and provides cited, accurate answers. Used by 10+ million users who need research-grade answers without the noise of a traditional search engine. |
