Chat with PDF Using AI
Upload a PDF and talk to it like a person — ask questions, request explanations, or ask for an outline, and get answers grounded in the actual content.
Chat with PDF is Cruxly's AI chat that keeps the entire text of your uploaded document in context. Instead of hunting for the right paragraph by hand or flipping through dozens of pages, you just ask — and get an answer grounded in the document's actual content, not the model's general knowledge. The same feature works for YouTube videos too — if you've already analyzed a video on Cruxly, the same chat is available for it.
