Ask Questions, Get Answers from Any PDF

Chat with PDF turns your static documents into interactive conversations. Whether you're reviewing a lengthy contract, studying a research paper, or digging through a technical manual, our AI-powered chat lets you ask natural-language questions and receive accurate, context-aware answers drawn directly from the document.

How It Works

Upload your PDF and our system parses every page, building a semantic index of the content. When you type a question the AI searches the most relevant passages, synthesizes the information, and responds in plain language. Sources are cited so you can verify every answer against the original text.

AI-Powered Document Analysis

The underlying model understands tables, lists, headings, and multi-column layouts. It can compare sections, extract key figures, and even explain complex terminology found in your PDF. All processing happens securely — your files are never stored longer than the duration of your session.

Use Cases

Students use Chat with PDF to study textbooks and highlight important concepts. Lawyers review contracts and surface specific clauses in seconds. Researchers cross-reference findings across multiple papers. Business analysts pull data points from quarterly reports without reading every page. Whatever your workflow, chatting with your PDF saves hours of manual searching.

Is my PDF data safe?+
Yes. Your file is processed in real-time and never stored on our servers. Once you close the tab, the file is gone. We don't train AI models on your documents.

Can I ask follow-up questions?+
Absolutely. The AI remembers the context of your conversation, so you can ask follow-up questions just like chatting with a colleague who read the document.
How accurate are the answers?+
The AI is very accurate for factual questions about the document content. For subjective analysis, it provides well-reasoned responses based on what's in the PDF. Always verify critical information.
Do I need to create an account?+
No. Chat with PDF works instantly — no signup, no login, no email required. Just upload and start asking questions.
What languages are supported?+
The AI can understand and respond in over 50 languages. You can upload a document in one language and ask questions in another.
