Chat with Your PDF Using AI
Got a 100-page report and need one specific fact? Instead of reading the whole thing, ask a question and get an answer with the exact page it came from. Chat with PDF lets you have a conversation about your document — ask follow-ups, request clarification, explore the content interactively.
How to Chat with Your PDF Using AI
- 1Load the PDF into the chat tool
Drop your PDF onto the chat page. The tool extracts text from the document in your browser using PDF.js. The extraction is local — your PDF file stays on your device. Only the extracted text is used for the chat context.
- 2Wait for AI processing
The extracted text is indexed and prepared for the AI model. Depending on document length, this takes a few seconds. A progress indicator shows the indexing status. You can see the document preview while the AI processes.
- 3Start asking questions
Type your question in natural language. 'What is the revenue forecast for 2026?' or 'Summarize the key findings.' The AI searches the document content and returns an answer with citations pointing to specific sections or pages.
- 4Review answers and follow up
Each answer includes references to the source text so you can verify against the original. Ask follow-up questions to dig deeper. The chat maintains conversation context, so 'tell me more about that' works naturally.

Chat with PDFFrequently Asked Questions
Is my PDF content sent to the AI when I chat with it?
Only the extracted text content is sent to the AI service. The original PDF file, its images, formatting, and metadata stay in your browser. You can use your own API key for maximum privacy.
What kind of questions can I ask about my PDF?
Any question about the document content. Summarize key points, extract specific data points, compare arguments across sections, explain concepts mentioned in the document, or find specific clauses. The AI is particularly good at synthesizing information spread across different pages.
Does the chat remember previous questions?
Yes, the chat maintains conversation context. You can ask follow-up questions and the AI understands references to earlier parts of the conversation. The context window is limited by the AI model's token limit, so very long conversations may lose early context.
What's the maximum PDF size for the chat feature?
The tool handles documents up to several hundred pages. The limiting factor is the AI model's context window. Very large documents may be truncated to fit within the model's token limit, focusing on the most relevant sections.
Can I use the chat tool offline?
No. Chat with PDF requires an AI service connection. Unlike our purely local tools (merge, split, compress), the chat feature sends extracted text to an AI provider. The PDF file itself stays local, but the AI processing requires an internet connection.
Your PDF stays on your device
Only extracted text is sent to the AI service. The PDF file, images, and formatting never leave your browser. Use your own API key for full privacy control over what data is transmitted.
