ChatDOC is an AI-driven document assistant designed to make interaction with lengthy or complex files simple and intuitive. Instead of manually reading through pages of text, searching tables, or trying to interpret formulas, you upload your document—whether it is a PDF, Word, scan, Markdown file or even a website link—and ChatDOC allows you to ask questions in plain language. The system processes the document, uses optical character recognition (OCR) when needed, extracts text, tables and formulae, and then lets you query the material as though you were chatting with it. The responses include citations or footnotes referencing the exact location in the original document so you can verify and trace back sources if required. This makes ChatDOC particularly useful for researchers, legal professionals, students, business analysts or anyone dealing with large volumes of content. You can request summaries, ask for explanations of specific blocks of text, transform visual content like tables or formulas into textual explanations, and work across multiple files in one conversation thread. A free plan offers limited uploads and queries, letting you test the service. Upgrading to a paid tier unlocks higher file sizes, unlimited pages per document, use of more advanced models (for example GPT-4), API access and more nuanced query capabilities. The platform includes documentation and user guides to help you organise your workflow and get the most out of your files. With its combination of document-type flexibility, citation-backed answers and conversational interface, ChatDOC stands out as a productivity tool for unlocking insight from content that would otherwise demand manual review.
