What it’s for
The Prompt Composer is where you write and send a question in Chat. The text box reads What would you like to know about your business? A few controls sit around it.
Before you start
Everyone who can use Chat has the composer. Some settings, such as Web Fetch, show only when your company has them turned on.
Steps
Write and send
- Type your question. Drag the text box to resize it for a longer prompt, or choose Expand to open the composer full screen. Escape closes it.
- Type @ to mention documents, metrics, users, tables, Signals, projects or shared items. Each mention becomes a chip that guides the assistant to the right resource. Chips persist with the conversation.
- Read the prompt quality coach next to Send. It gives you feedback on what you write before the assistant runs.
- Choose Send, the arrow. While an answer runs, it becomes Stop.
Add files and templates
- Choose Chat Tools, the plus.
- Choose Add files (Ctrl+U) to attach a file, or search documents you already uploaded by name.
- Or choose Templates to start from a prompt template. You can also open templates from the @ menu.

Chat can read the documents you attach, including spreadsheets, PDFs and Word files.
Change chat settings
- Choose Chat Settings, the cog.
- Turn on or off Assisted Prompting, Sequential thinking, Web Fetch, Syntax highlighting, Dark mode and Full width. Each has an About item that explains it.

Set your defaults for these in Profile. See Setting your user preferences.
Pick the model
- Open the composer’s model menu and pick the model for this chat.
- Choose Use as default for new chats to make it your default.
