| Description | ChatDOC is a cloud-based AI file-reading assistant that lets you upload PDFs, Word docs, scans, web pages, EPUB, Markdown, and text files, then ask questions and get answers grounded in the document. It's built for students, researchers, and professionals who need to digest long or complex documents quickly, and its main differentiator is TapSource citations that link every answer back to the exact footnote, table cell, or highlighted passage in the source so you can verify it. It also parses cross-page tables, formulas, and images and can translate files while preserving the original layout. | ChatGPT by OpenAI is the world's most popular AI assistant with 200+ million weekly active users. From writing and coding to research and creative tasks, ChatGPT helps people get more done with conversational AI. |
