BrainyPDF

BrainyPDF lets you chat with PDFs using AI. Ask questions, get summaries, and extract key insights from your documents in seconds.

BrainyPDF is an AI-based PDF assistant that enables users to ask questions about PDF files and receive intelligent, contextual answers. Whether you’re reading a dense research paper, legal contract, instruction manual, or business report, BrainyPDF helps you save time by summarizing, highlighting, and answering questions from within the document — all through a conversational interface.

Designed for students, educators, researchers, and business professionals, BrainyPDF makes document analysis more interactive, personalized, and efficient, all without requiring users to scroll through hundreds of pages manually.

Features

How It Works

  1. Upload a PDF File: Drop a PDF into the browser or click to upload a file.

  2. AI Pre-Processing: BrainyPDF scans and indexes the content to understand structure and context.

  3. Ask a Question: Type any question about the document such as “What is the main conclusion?” or “Summarize section 2.”

  4. Receive an Answer: The AI responds with a well-formulated, context-aware answer in seconds.

  5. Continue the Conversation: Ask follow-up questions to dig deeper into specific parts of the document.

  6. Close and Exit: Your session ends when the browser tab is closed, with all uploaded files deleted soon after.
