You have a 200-page report and need to find specific information — what does the policy say about parental leave, what was Q3 revenue, what's the risk assessment for project X. Reading the whole document is slow; Ctrl+F finds keywords but misses paraphrased mentions. PDFKits Chat with PDF lets you ask natural-language questions and get cited answers grounded in the document. Free, no signup, with the AI inference running through a privacy-respecting backend.
The tool extracts text from your PDF, chunks it semantically, then for each question runs retrieval-augmented generation (RAG): it pulls the most relevant chunks and asks a large language model to answer using them, with citations to the source pages. You get an answer plus the specific page numbers where the supporting content lives — verifiable, not just hallucinated. Works for legal contracts, research papers, technical documentation, financial reports, and any structured PDF.
Drop the file. PDFKits extracts text via pdf.js (locally in your browser) and chunks it into semantically meaningful pieces.
Type a natural-language question in the chat box. PDFKits finds the most relevant chunks via vector similarity and sends only those (not the full PDF) to the AI provider for answer generation.
The response appears with footnote-style citations to the source page numbers. Click a citation to jump directly to that page in the PDF preview. Continue the conversation with follow-up questions — the context persists in your browser session.
"What's the termination clause?" "What's the SLA penalty?" "Is there an exclusivity term?" — answered with citations to specific contract sections in seconds.
Students and researchers explore unfamiliar papers by asking "what's the main hypothesis", "what data did they use", "what are the limitations" before reading in full.
Engineers find specific API behaviors, configuration options, or troubleshooting steps in long product manuals without scrolling through 500 pages.
Employees ask HR policies — "how many sick days do I get", "what's the work-from-home policy" — and get cited answers from the company handbook PDF.
Adobe Acrobat AI Assistant costs $5/month extra on top of the $19.99 Acrobat subscription. ChatPDF.com requires signup and uploads your file. PDFKits Chat with PDF is free, no signup required. Text extraction runs entirely in your browser. Only the question and the most relevant text chunks (not the full PDF) are sent for AI inference — minimizing data exposure while keeping the feature usable.
No. PDFKits extracts text in your browser, then for each question sends only the most relevant chunks (typically 2-4 paragraphs) to the AI provider for inference. The full PDF binary never leaves your device.
Citations make the answers verifiable. Always check the cited pages — RAG-based AI is good at retrieval but can still occasionally misinterpret. For high-stakes decisions, verify the answer against the source.
English, French, Spanish, German, Portuguese, Italian, Chinese, Japanese, Korean, and most major languages. The AI handles questions and PDFs in different languages, including cross-lingual Q&A.
Practical limit is ~50 MB or ~500 pages. Larger documents can be split first using our Split PDF tool, then queried in parts.
Yes — copy the chat or use the export option to save the Q&A as a text/PDF file.
Search finds exact keyword matches. Chat understands semantic meaning — you can ask 'what's the punishment for late delivery' and it finds the relevant clause even if those exact words don't appear.
Currently one PDF per session. For multi-document Q&A, merge them first with our Merge PDF tool.
