What is ChatDOC?

ChatDOC is a web tool for asking questions about documents. You upload a file, or a folder of files, and each answer comes with footnotes that jump to the passage, table or figure it was drawn from. It parses cross-page tables, formulas and scanned pages, translates whole documents, and lets users plug in their own API key for models from OpenAI, Gemini, DeepSeek and others. Chrome and Edge extensions and a developer API are also offered.

ChatDOC is a paid product with a free trial, starting at $89.9 per 360 days (a 30-day plan is also sold). See every plan
