Visit chatpdf.com and drag any PDF, Word, or PowerPoint file onto the upload area — no account creation needed to start your first conversation with a document. Type a natural language question about your document in the chat box (e.g., 'What are the main conclusions of this paper?' or 'Summarize section 3') and press Enter to receive an AI
generated answer with page citations. Review the AI response and click on page citations to verify answers against the original document text. Create a free account to unlock saved chat history, multi
document folders, and the prompt library for reusable queries. Upgrade to ChatPDF Plus ($
99/month) for unlimited document uploads, 2,000

💡 Quick Start: Follow these 5 steps in order to get up and running with ChatPDF quickly.
Explore the key features that make ChatPDF powerful for document ai workflows.
Upload PDFs, Word documents, PowerPoint presentations, Markdown, and text files without creating an account. Drag-and-drop or click to upload, and ChatPDF immediately processes the file, generates an automatic summary, and suggests starter questions — all within seconds. This no-account-needed approach removes the onboarding barriers that slow down most AI tools, making it ideal for first-time users or anyone who needs a quick answer from a document without committing to a new platform.
Ask natural language questions about uploaded documents and receive accurate, contextual answers with specific page-level citations. Every response references the exact section of the document it drew from, allowing users to click through and verify the AI's interpretation against the source text. This citation-first design makes ChatPDF more trustworthy than general-purpose chatbots for document analysis, especially in academic, legal, and compliance contexts where source verification is essential.
ChatPDF intelligently routes queries between GPT-4o for complex analytical questions and GPT-4o-mini for straightforward factual lookups. The system automatically determines which model to use based on query complexity, optimizing the balance between response quality and speed without any user configuration. Simple questions like 'What is the publication date?' use the faster model, while nuanced questions like 'Compare the methodology across sections 3 and 5' leverage GPT-4o's deeper reasoning capabilities.
Create folders containing multiple documents and query across all of them simultaneously. The AI understands relationships between documents within a folder, enabling cross-referencing, comparative analysis, and synthesis across up to 50 PDFs. This feature is particularly valuable for literature reviews, legal due diligence, competitive analysis, and any workflow where insights emerge from comparing multiple sources rather than reading each document in isolation.
Upload documents in any language and ask questions in a different language. ChatPDF handles cross-language interaction seamlessly, translating and contextualizing responses without requiring separate translation steps. This makes it especially useful for international research teams, multilingual organizations, and users working with foreign-language academic papers, contracts, or regulatory documents who need answers in their preferred language.
Generate secure links to share specific documents with collaborators who can access them for free without needing their own ChatPDF account. Shared documents are read-only by default, and the document owner retains full control including the ability to revoke access at any time. This feature enables teams to distribute document insights without requiring everyone to upload their own copy or subscribe to the service.
Save frequently used prompts and apply them across different documents. Useful for standardized analysis workflows like extracting key findings from research papers, identifying risk clauses in contracts, summarizing executive reports, or pulling specific data points from financial statements. The prompt library turns repetitive document analysis into a streamlined, consistent process, reducing the time and effort needed for recurring tasks.
REST API enables programmatic document upload, question submission, and answer retrieval. Build document Q&A capabilities into custom applications, internal tools, or automated workflows using API key authentication. The API supports uploading documents via file or URL, submitting questions against uploaded documents using source IDs, and managing document lifecycle including deletion. It is suitable for developers building document intelligence features without constructing their own RAG pipeline from scratch.
