ChatDOC is a document Q&A service: upload a file, ask questions, and get fast answers, clear explanations, and concise summaries of long materials.
Ask questions across document formats
ChatDOC supports multiple formats, so you can work with more than just PDFs:
- DOC/DOCX
- Scans
- Web pages
- EPUB
- Markdown
- TXT
It can answer questions about tables, formulas, and images, and it keeps context across different pages.
Verifiable answers with sources
With TapSourceβ’, you can see where an answer comes from:
- Links to the exact passages used
- Quick checking of quotes and conclusions
This is useful for studying, research, legal documents, and day-to-day work files.
Translation and large document libraries
ChatDOC can help translate materials while preserving the original layout. Itβs also designed for working with large numbers of files and pages, so you can find what you need without manually scrolling through long documents.
