PDF AI: Chat with any PDF

Chat with any PDF using AI: ask questions, summarize, search big documents and scanned files. Every answer cites its page.

Chat with any PDF right in your browser. PDF AI opens as a side panel next to the document you are reading and answers questions about it — with the page number behind every claim, so you can check the source in one click. WHAT IT DOES • Ask questions in plain language and get answers grounded in the document, not in guesswork. When the answer is not in the file, it says so. • Summarize a contract, paper, report or manual in seconds. • Handles big documents. A long PDF is not stuffed into the AI blindly — the assistant sees its outline and searches inside by meaning, reading only the sections it needs. Works comfortably on reports of 100+ pages. • Reads scanned PDFs. If a document has no text layer, built-in OCR recognizes the pages locally in your browser before the chat starts. • Chat with several PDFs at once. Select multiple files and they are merged into one conversation, with answers naming the file and page they came from. • Every answer cites its pages, quotes exactly when wording matters, and renders clean formatting for lists and tables. HOW IT WORKS Open a PDF and click the extension icon, or use the chat button that appears in the corner of PDF pages. The text of your document is extracted on your computer. When you ask a question, only the relevant content is sent to the AI service to produce the answer — the extension itself stores no API keys and requires no configuration. Works with PDFs opened from the web, from local files (enable "Allow access to file URLs" in the extension settings, or simply use the Load files button), and behind logins via the file picker. WHO IT IS FOR Students working through papers and textbooks, lawyers scanning contracts for specific clauses, researchers extracting numbers from long reports, accountants checking invoices, and anyone who would rather ask a 300-page document a question than read it whole. LANGUAGES The assistant understands documents and questions in many languages, including English, German, French, Spanish, Portuguese, Russian, Japanese, Korean, Chinese, Hindi, Indonesian, Turkish, Polish, Dutch and Vietnamese. OCR for scanned files currently supports English text. More at https://pdf-ai.online Questions or problems? Contact us through the support tab — feedback directly shapes what gets built next.
