Everything you need to know about PDFChat
PDFChat is an AI-powered PDF question-answering tool. Upload any PDF document and ask questions in natural language - the AI will understand your question, search through the document, and provide accurate answers with source citations. It uses advanced RAG architecture combined with Tongyi Qianwen's qwen-long model for deep document understanding.
PDFChat primarily supports PDF files. You can upload PDFs up to 50MB in size. The AI can process documents with hundreds of pages and understand content in multiple languages including Chinese, English, Japanese, Korean, and more.
PDFChat provides highly accurate answers based on the actual content of your PDF documents. Every answer includes precise page citations so you can verify the information directly in the original document. The AI will indicate when it cannot find relevant information in the document rather than making up answers.
Yes, security and privacy are our top priorities. Documents are processed in isolated environments and are not stored permanently on our servers after processing. We do not use your documents to train AI models. All data is encrypted in transit and at rest.
PDFChat offers three pricing tiers: Free plan with 1M tokens/month, Pro plan at $9/month with 10M tokens/month and priority processing, and Enterprise plan at $29/month with unlimited tokens. See our pricing page for full details.
Tokens are the units of text processed by our AI. Approximately 1 token equals 2 characters in English. A typical 10-page PDF contains roughly 30,000-50,000 tokens. The Free plan (1M tokens) allows you to process about 20-30 average PDFs per month, while Pro (10M tokens) supports 200-300 PDFs.
