Key Features & Benefits

Ask Questions About Any PDF

Upload any PDF document and ask questions about its content. The AI reads and understands the entire document, providing accurate answers based on what is actually written in the file.

Page References

Every answer includes references to the specific page or section where the information was found. This makes it easy to verify the AI's responses and navigate directly to the source material in your document.

Client-Side PDF Extraction

Your PDF is processed entirely in your browser using client-side technology. The raw file is never uploaded to any server — only the extracted text is sent to the AI for analysis, ensuring your document privacy.

Follow-Up Questions

Ask as many follow-up questions as you like while your document stays loaded. The extracted text remains in your browser, so every answer is grounded in the full document without re-uploading anything.

Key Topic Extraction

Every answer highlights the key topics it covers, giving you a quick view of the themes inside your document and helping you decide what to ask about next.

Reliable Text Extraction

PDF text extraction runs entirely in your browser and handles long files reliably. The text sent to the AI is capped at about 16,000 characters (roughly 4,000 tokens) per question - for very long documents, split the PDF or ask about one section at a time.

Related Sections

When other parts of the document are relevant to your question, the AI lists them alongside the answer so you can jump straight to the most useful passages without scrolling through the whole file.

Copy & Export Answers

Copy any AI response to your clipboard with a single click for use in your notes, reports, or presentations. Each answer preserves its formatting and page references for easy reference.

AI PDF Reader – Frequently Asked Questions

How does the AI PDF Reader work?
Upload a PDF file and the tool extracts the text content using client-side PDF processing. The extracted text is then sent to an AI model that can answer your questions about the document. The AI provides answers with page references so you can verify the source.
Is my PDF file uploaded to a server?
No. The PDF file is processed entirely in your browser using client-side JavaScript. Only the extracted text is sent to the AI for analysis. Your original PDF file never leaves your device, ensuring complete document privacy.
What types of PDFs are supported?
The PDF Reader supports text-based PDFs including reports, research papers, contracts, manuals, and articles. Scanned PDFs (images of text) may not work well because the tool extracts text, not images. For scanned documents, use the OCR tool in Visual Lab first.
How many questions can I ask about one document?
You can ask as many questions as you like about a single document during one session. Each question counts as one use of the tool and is answered against the full extracted document, so you can ask follow-ups at any time without re-uploading anything.
Can the AI read tables and charts in PDFs?
The AI can read text that is extracted from PDFs, including text within tables. However, visual charts and graphs that are rendered as images cannot be read by the text extraction engine. For image-based content, use the OCR tool instead.
What is the maximum PDF size I can upload?
Text extraction in your browser handles PDFs up to 50 pages and around 10MB. The text sent to the AI is capped at about 16,000 characters (roughly 4,000 tokens) per question. For longer documents, split the PDF or ask about specific sections - the file itself never leaves your device.
Are the AI's answers always accurate?
The AI provides answers based on the document content, but like any AI system, it can occasionally misinterpret context or miss nuances. Always verify important answers against the original document, especially for legal, medical, or financial content.
Is the PDF Reader free to use?
Yes, the PDF Reader is free to use with daily usage limits. Each question you ask counts as one use. No credit card is required. You need a free account to use this tool.
