ChatDOC vs PDFCite

ChatDOC is a web document assistant that lets you converse with uploaded files in natural language. It can summarize, extract, locate, analyze, and rewrite content from PDFs, Word files, Markdown, ePub, TXT, and scanned documents. A folder upload supports questions spanning multiple documents. Responses include page and reference citations, links that highlight source passages, and highlighted numerical values for checking answers. ChatDOC provides an API for embedding document processing and generated responses in other applications. Its PDF Parser API recognizes text, tables, and images and converts PDF material into formats such as JSON. Processing requires an internet connection. The service runs on the web, through a browser extension, and via API. A free plan is available; Pro costs $8.99 a month or $89.90 a year, with larger limits.
