ChatDOC vs Doxy

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.

Doxy is a web document-chat app for asking questions about uploaded files and other source material. Users organise files into projects, ask questions in plain language and receive answers that cite the documents used. Supported inputs include PDFs, Word, PowerPoint, Excel, images, audio, HTML, CSV, ZIP and EPUB files, plus web links and YouTube URLs. YouTube questions use the video transcript. Users can upload and ask questions in many languages, with answers in the question’s language where the source supports it. Pro and Business plans generate multiple-choice quizzes with explanations and open-ended practice exercises from selected sources. The Free plan costs nothing for 3 documents, 20 questions monthly and 10 MB files. Pro costs $4.99 a month for 100 documents, 1,000 questions monthly and 50 MB files. Business costs $9.99 a month with unlimited documents and questions and 200 MB files. An account is required.
