Integrations

ChatDOC integrations

ChatDOC works mainly as a standalone web application, with a Chrome extension for reading documents and web pages in the browser and access from mobile devices. Users upload files directly, including PDF, DOC, DOCX, EPUB, Markdown, TXT, scanned documents, and website links, rather than connecting to third-party storage or business systems. The underlying PAI Tech PDF parser handles layout and table extraction, and the Pro plan adds optional access to more advanced language models such as GPT-4o. Teams that need ChatDOC inside their own applications can look at ChatDOC Studio, the vendor's related offering, for developer and embedding options beyond the consumer app.
