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?", "Summarize the risks identified." The AI reads the document and answers immediately. It's like having a research assistant who has read your PDF in full and is ready to answer questions about it.

Is my PDF content sent to Google?
The text extracted from your PDF is sent to the Google Gemini API to generate answers. The raw PDF file itself is not uploaded — only the extracted text content. Google's API terms apply to the text content. For highly sensitive documents, consider whether you're comfortable with the text being processed by Google's AI service.
Frequently asked questions
Does it work on scanned PDFs?
Scanned PDFs don't have a text layer — the AI needs text to read. For scanned documents, you'd need to run OCR first to create a text layer.
What's the maximum PDF size?
Very large PDFs may hit Gemini's context window limits. For best results, use PDFs under 100 pages or split a large document and chat with each section.
Is there a cost?
The Google Gemini free tier covers everyday personal use. ihatepdf itself is completely free.
