The library holds your own material — product notes, research, case studies, transcripts. It's what stops a draft being written from general knowledge when it should be written from yours. The Content Library screen showing folder chips, a document card with its size and status, and controls for adding content ## Adding files Use **Add Content** in the top right. Uploaded files show a size, the folder they're in, and a status — **Ready** means it's been processed and can be used in chat. Give a new file a moment before relying on it. A file that hasn't finished processing won't contribute to what chat writes. ## Folders Files start under **All files**. Use **New folder** to group them, then assign a file to a folder from the dropdown on its card. Each folder chip shows how many files it holds. Worth doing early. A flat library is fine at five files and unusable at fifty, and moving things later is slower than filing them as you go. ## Finding things * **Search** by filename * **Filter** to narrow the list * **All time** to restrict by when a file was added * **Grid** or **List** — list is easier to scan once you have a lot ## Using it in chat The library is one of the context sources, labelled **Content Library** in the composer's **Use context from** menu. It's on by default, so anything you upload is available to draw on without further setup. Two ways to use it: Depost AI finds what's relevant across your library. Good when you're not sure which document matters. Use **Select from library** in the composer's **+** menu. Precise when you know exactly which file the request is about. Upload the things you find yourself explaining repeatedly — your positioning, how the product actually works, the case study you always cite. Those are what turn a generic draft into one only you could have written. ## Shared across the workspace Files uploaded at workspace level are visible to everyone in that workspace. Keep shared reference material there, and anything specific to one brand with that brand. ## Related How Content Library is used alongside your other sources. Point at one specific document for a single request. Where library material earns its keep. Reference material from other people, rather than your own.
