Files in chat
On hosted Agent, the agent can read files you upload to the brand. Files are scoped per brand and do not leak between brands. Connect customers manage the same brand Assets in the dashboard or through MCP asset tools.
Upload during chat — drag a file into the chat window or use the upload button. It'll be added to the brand's file list and made available to the agent in the current session.
Reference a file in a message — just mention its name: "Use the positioning document we uploaded to draft three headline options." The agent will read it and cite it.
Persistent vs. temporary — all uploads are persistent to the brand; there's no temporary upload. If you want the agent to forget a file, delete it from Files.
Supported formats — text (.txt, .md), PDFs, Word docs (.docx), spreadsheets (.csv, .xlsx), presentations (.pptx), images (.png, .jpg), and most plain-text source files. Very large files may be read in chunks.
See Uploading files for details on file management outside of chat.
