What is an AI PDF chat tool, and what should you expect from one?
An AI PDF chat tool lets you upload a PDF and ask it questions in plain English, instead of opening the file and reading it page by page. The AI reads the entire document, answers your question, and shows the page the answer came from. AskYourPDF is the AI PDF chat tool used by more than five million readers to chat with PDFs, generate summaries, and pull cited insights from documents in seconds.
Most AI PDF chat tools limit you to a few questions, a short document, and a single AI model. AskYourPDF is built to be the tool you actually use, not the one you sample and abandon. You get cited answers on every reply, OCR for scanned PDFs, support for documents up to 6,000 pages, and access to the full lineup of frontier AI models (GPT-5, GPT-5.2, GPT-5 Mini, GPT-5 Nano, Gemini 2.5 Flash, Gemini 2.5 Pro, Claude 4.5 Sonnet, and Claude 4.5 Opus) on a single subscription.
If you are a researcher running a literature review on 80 papers, an in-house lawyer reading a 90-page master service agreement, a strategy analyst working through a stack of industry reports, or a student reading a textbook the night before an exam, this page is for you. AskYourPDF is built so you can chat with the documents you actually have to read, in the way you would ask a colleague who already knows the file.
How to chat with a PDF in three steps
Three steps. The third one is the only one that takes any thinking on your part.
Upload your PDF document
Drag a PDF, DOCX, EPUB, or TXT file into the AskYourPDF chat reader, or paste a URL. We support documents up to 6,000 pages on Pro and 877 MB upload size. Scanned PDFs are processed with built-in OCR on Premium and above. Files stay private to your account, are stored on UK servers under GDPR, and are never used to train any AI model.
Ask your PDF a question in plain English
Type the way you would ask a colleague who has read the document. "Summarize this contract." "What is the methodology in chapter three?" "Find every clause about indemnification." You can ask follow-up questions in the same chat, and AskYourPDF keeps the full PDF context in mind across the conversation.
Get a cited answer in seconds
We return your answer with a citation back to the exact page in the original PDF. Click the citation to verify. No hallucinations, no guessing, no surprise paywall after the first message. Switch the underlying AI model per question if you need different reasoning depth or multilingual handling.

Chat with any PDF and get cited answers
You get the full conversational experience on every plan, with citations linking every answer back to the exact page. No five-message limit. No "upgrade to continue" walls mid-conversation. This is why AskYourPDF is the chat-with-PDF tool researchers and lawyers trust for verifiable work.
Switch between GPT-5, Claude 4.5, and Gemini 2.5 per question
AskYourPDF is the only chat-with-PDF AI tool that gives you access to the full frontier model lineup on a single subscription. Switch to Claude 4.5 Opus for legal nuance, Gemini 2.5 Pro for multilingual sources, or GPT-5 for general work.
Chat with multiple PDFs at once with a Knowledge Base
Premium and Pro let you group documents into a Knowledge Base and chat with all of them as a single library. Ask one question, get one cited answer drawn from across every file. Built for literature reviews, contract libraries, and multi-document briefings.
OCR for scanned PDFs, on Premium and above
Photographed contracts, scanned research papers, image-only PDFs. AskYourPDF processes them automatically on Premium, Pro, and Enterprise, so the AI chat reads scanned PDFs as cleanly as native-text PDFs.
Chat in over 100 languages
Ask in your language and get answers in your language. AskYourPDF reads and chats in over 100 languages, with Gemini 2.5 Pro available for the deepest multilingual performance.
Chat with PDFs on every device you use
Web, iOS, Android, Chrome extension, ChatGPT GPT, and the Zotero plugin. The same chat history follows you across all of them, on any paid plan.
Embed PDF chat into your own product with the API
Developers can use the AskYourPDF API to build chat-with-PDF features directly into their own SaaS or internal tools. Same multi-model backend, same citations, same Knowledge Base support.
Your data stays yours
AskYourPDF is GDPR-compliant, hosted in the United Kingdom, and your documents are never used to train any AI model. Knowledge Bases are private to your account unless you explicitly choose to share them.
