What does "chat with PDF" mean?
Instead of reading a 50-page report yourself, you upload it and ask questions in plain English: "What are the main conclusions?", "What does section 4 say about pricing?", "List all the deadlines mentioned." The AI reads the entire document and answers immediately. It's like having a research assistant who has read your PDF in full and can answer follow-up questions about any part of it.

- "Summarize this document in 3 bullet points"
- "What are the payment terms in this contract?"
- "List all the deadlines mentioned in this report"
- "Does this document mention [specific term]? What context?"

Need a summary without the chat interface?
If you just need a quick structured summary without back-and-forth questions, use AI PDF Summarizer instead — it generates bullet-point key takeaways in one click without requiring an API key.
Privacy: what stays local and what reaches Google
It is worth being precise about how this works, because "AI" and "private" are often oversold. Your PDF file is never uploaded to an ihatepdf server — the document is opened and its text extracted in your browser. To actually answer your questions, that extracted text is then sent to Google's Gemini API using your own key, because the language model runs on Google's infrastructure, not your device. So ihatepdf never sees your content, but Google's API does process it under your account's terms. For genuinely confidential material that must never leave your machine, extract the text and review it locally, or use the on-device summarizer instead.
Get better answers: how to ask
The quality of the answer follows the quality of the question. Be specific — "What is the late- payment penalty in section 7?" beats "Tell me about payments." Ask the model to quote the source ("quote the exact clause and its heading") so you can verify it against the document. Break complex requests into steps, and for long contracts ask it to list every instance of a term rather than summarise, so nothing is missed. If an answer seems off, ask a follow-up — the model keeps the document in context for the whole conversation.
Frequently asked questions
Which documents work best with Chat with PDF?
Any text-based PDF — reports, contracts, research papers, manuals. The clearer the text layer, the better the answers. Scanned documents need OCR first.
Is the Google Gemini API really free?
Yes. Gemini has a generous free tier that covers everyday personal use with no credit card required. Very heavy use can hit rate limits, at which point Google offers paid tiers.
Does it work on scanned PDFs?
Scanned PDFs don't have a text layer. Run OCR first to add a text layer, then the AI can read and answer questions about the content.
Is my PDF content sent to Google?
The extracted text content is sent to Google Gemini API to generate answers. The raw PDF file itself is processed locally — only text is transmitted. Google's standard API terms apply to this text content.
Is there a cost?
The Google Gemini free tier covers everyday personal use. ihatepdf itself is completely free.
