# Attachments & Context ## Dropping files into chat In **Chat All** mode, you can drop files directly into the chat input. This narrows the search to only those files — useful when you want answers from specific documents without searching your entire library. Files appear as chips above the input. Remove a chip to stop searching that file. ## Context label The label above the chat input always tells you what's being searched: * **"Chatting with all"** — searching your entire library * **"2 dropped files only"** — searching only the files you dropped * **"2 files + Library"** — dropped files plus your library ## YouTube in chat Paste a YouTube URL directly into the chat. Knowbase extracts the transcript on the fly so you can ask questions about the video without uploading it to your library first. ## Library toggle Use the **library icon** in the input bar to include or exclude your uploaded library from the search. This is useful when you only want to search dropped files or connected tools. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.knowbase.ai/chat/attachments-and-context.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
