Chat with PDF — Ask Your Documents Anything
Upload a PDF, DOCX, or TXT and ask questions in plain language — answers come straight from your document.
What is Chat with PDF?
Cobain AI's Chat with PDF lets you upload a document and ask it questions like you would a person. Drop in a research paper, contract, report, or manual, then ask anything — the AI reads the file and answers based on what's actually written inside it, not guesswork.
