Chat with PDF – Free AI PDF Assistant

4 min read · Updated June 2026

Imagine being able to ask questions about any PDF document and get instant answers — without reading through hundreds of pages. That's exactly what our free Chat with PDF tool does. Upload a research paper, contract, book, or report, and start asking questions. The AI reads the document and answers based only on what's in the file.

What Can You Use It For?

  • Research papers — Ask about methodology, findings, or conclusions without reading the full paper
  • Contracts & legal docs — Find specific clauses, terms, or obligations quickly
  • Textbooks & manuals — Get explanations of concepts or locate specific instructions
  • Reports & proposals — Extract key data points, summaries, or recommendations
  • E-books & articles — Discuss themes, characters, or arguments from long-form content

How It Works

  1. Upload your PDF — Go to our Chat with PDF tool and select your file (up to 20MB).
  2. Text is extracted — PDF.js extracts all text from every page, right in your browser. The actual file never leaves your device.
  3. Ask questions — Type any question about the document content and get AI-powered answers instantly.

Privacy First

Your PDF file never leaves your device. Text extraction happens entirely in your browser using PDF.js — an open-source library from Mozilla. Only the extracted text is sent to our AI API to answer your questions. The original file stays on your computer. This is fundamentally different from services that require you to upload your document to their servers.

Free vs Premium

Free users get 3 questions per day to try the feature. Premium subscribers get unlimited questions, larger file support, and priority processing — perfect for professionals who work with documents daily.
