Chat with PDF

What is Chat with PDF?

Chat with PDF lets you ask any question about a document and get an answer grounded in the document itself, not a generic web search. You upload a PDF, the text is extracted locally in your browser, and the AI answers questions based on that extracted text. Useful for contracts you need to interrogate ("what is the termination notice period?"), research papers ("what statistical test did they use?"), product manuals ("how do I reset to factory defaults?"), and meeting minutes ("what did we agree to do by next Friday?"). The PDF file itself never leaves your browser. Only the extracted text is sent to our AI provider so it can answer your question, and nothing is stored after the response is returned. No account, no upload of the binary, no watermark.

Why use this tool?

The PDF binary never leaves your browser, text extraction runs locally using PDF.js. Only the extracted text is sent to our AI provider for the answer, and we do not log, store, or use it for training. Answers stream in 2–6 seconds and cite the part of the document they came from where possible. You can ask unlimited follow-up questions in the same session (the AI keeps the full document context), and you can switch to the Summarizer view at any time. There is no signup, no watermark, no daily cap, and the tool works on Windows, macOS, Linux, iOS Safari, and Android Chrome.

Common use cases

Reach for Chat with PDF when you need a specific answer from a long document and do not want to read it end-to-end. Common cases: a lawyer asking targeted questions about a 60-page contract; a procurement analyst extracting renewal terms from a vendor MSA; a developer pulling configuration details out of a thick spec; a student preparing for an exam by quizzing a textbook chapter; a hiring manager asking what a candidate emphasised in a long resume; a finance team pulling specific line items out of an audit report. It is also the right fit when a plain search of the PDF would miss the answer because it is phrased differently than your question, the AI understands intent and synonyms, so "what is the SLA?" finds the right paragraph even if the document says "service level commitment".

Frequently asked questions

Does my PDF get uploaded to a server?

No, the PDF binary stays on your device. Text extraction runs locally in your browser using PDF.js. The extracted text is sent to our AI provider so it can answer your question, but the file itself is never uploaded, and the text is not logged, stored, or used to train any model.

How accurate are the answers?

Answers are grounded in the extracted text, so for text-native PDFs (typed contracts, exported reports, research papers) accuracy is high. For scanned PDFs without OCR, image-only pages, or PDFs with complex tables and equations, extraction loses fidelity and answers may miss details. For high-stakes decisions, always verify the answer against the original document.

How long can the PDF be?

Documents up to ~50 pages are loaded into a single context for the AI. Larger documents are still supported, the tool retrieves only the most relevant sections to answer each question, so you can chat with a 200-page report without hitting context limits.

Can I ask follow-up questions?

Yes. The session keeps the full document context, so follow-ups like "and what about the renewal clause?" work correctly without re-uploading or re-explaining what the document is.

Does it work on scanned PDFs?

Only if the scan has been OCR'd (so the text is selectable). Pure image scans with no text layer cannot be read, run them through an OCR tool first to add a text layer.

What kinds of questions work best?

Specific questions ("what is the indemnification cap?", "list every deadline in section 4") work better than open-ended ones ("is this a good contract?"). The AI is a research assistant, not a domain expert, it can find and explain what is in the document but should not be the only basis for legal, medical, or financial decisions.

Can I download the conversation?

Yes. The full transcript (your questions and the AI's answers) can be copied to your clipboard or downloaded as a text file for later reference.

Is there a usage limit?

There is a fair-use rate limit to prevent abuse, but no daily cap for normal use. Hit the limit and you can continue after a brief cooldown. No paid tier required.

1. 1Ask specific, scoped questions, "what is the late-payment penalty in section 5?" gets a better answer than "is this contract fair?". The AI is best at retrieval and explanation, not subjective judgment.
2. 2For long documents, start by asking the AI to list the section headings, then drill into the sections that matter. Faster than scrolling through 100 pages.
3. 3If an answer feels off, ask the AI to quote the source paragraph. That makes it easy to verify against the original PDF.
4. 4For scanned contracts without OCR, run them through an OCR tool first, otherwise the AI has nothing to read.

How does it compare?

ChatGPT and Claude both let you upload a PDF, but they store the file on their servers and require an account, often a paid one for longer documents or higher usage. Adobe Acrobat AI Assistant costs $4.99/month on top of a Pro subscription. ImageAndPDF.com extracts text in your browser (the PDF binary never uploads), runs the AI without storing your text, has no signup, no watermark, and is free.
