ChatPDF — Conversational AI for Documents
ChatPDF is a purpose-built document-AI platform that applies conversational LLM capabilities to PDFs, Office files, images and web content. It lets users upload documents or paste links and then interact with the content through natural-language chat. Responses include anchored citations and quick links back to the original source for easy verification.
Key features
- Conversational document QA: Ask questions in natural language and get concise, context-aware answers based on the uploaded files.
- Multi-file chats & folders: Combine multiple PDFs or documents in a single chat to compare, cross-reference, and synthesize across sources.
- Cited sources & side-by-side view: Answers include citations that link to exact pages/sections and a split view keeps the document and chat visible together.
- Summaries & translation: Generate article or chapter summaries and translate documents into your preferred language.
- Broad file support: Accepts PDFs, Word (.doc/.docx), PowerPoint (.ppt/.pptx), Markdown (.md), text, and common image formats (JPG/PNG) for OCR-style workflows.
- No sign-up trial + paid tier: Free access (limited daily documents) with a Plus plan offering higher throughput and features.
- Security & compliance: TLS/SSL in transit, encrypted storage, and enterprise-grade storage options claimed (SOC2 Type II provider).
- Smart routing to LLMs: Platform optimizes queries across performant models (mentions GPT-4o/GPT-4o-mini routing) for speed and quality.
Primary use cases
