Document chat is a feature that uses Artificial Intelligence to extract information from documents. Users can type queries into a chatbox, and the AI interprets these queries to provide relevant results. This makes it easier and faster to find information without manually searching through the document. The AI's ability to understand and respond accurately to queries saves time and boosts productivity. Users can also refine their queries based on the AI's responses. Overall, document chat transforms how users interact with documents, making information retrieval quick and efficient.
