What Is ChatPDF?
ChatPDF does one job and does it fast: upload a document and ask questions about it, with clickable citations that scroll directly to the source passage rather than making you hunt through the file yourself. It's expanded beyond pure PDFs to support Word, PowerPoint, Markdown, and text files, plus multi-file folders, YouTube video chat, flashcard generation, and an AI Writer and AI Detector, but the core "upload and ask" experience remains its clearest strength.
Its dynamic routing between GPT-4o and GPT-4o-mini balances speed, quality, and cost across different question types, and for clean text-based PDFs it responds in 3-5 seconds regardless of document length — genuinely faster than NotebookLM or uploading a document to Claude, according to independent 2026 comparisons. Pricing is straightforward: free at 2 PDFs daily and 50 questions per PDF, $5/month for Plus (50 PDFs daily, 500-page limit), and $15/month for Max (500 PDFs daily, 2,000-page limit).
It's aimed at anyone who wants the fastest possible way to ask questions about a specific document with verifiable citations, rather than a broader research or note-taking platform. See our Research & Search category for tools like NotebookLM if you need a more comprehensive research workspace.
