Sometimes a conversation assumes background that has never been spoken aloud. Context is that supporting information. On the desktop app, open Files to inspect the documents attached to this session. Our fictional Willow Cafe launch brief is ready and marked In context. That indicator tells us it is included. Excluded means it remains attached but is not selected as background. Give the next question a clear purpose. For example: compare the conversation with the launch brief, and identify decisions still needed. The brief supplies a reference; the question tells the app what to do with it. Review the answer against both sources. Give the assistant the background that makes an answer useful. On the desktop app, open Contexts from Chat, then choose Add New Context. Start with a name you will recognise later. Our fictional example is Willow Cafe launch planning. Conversation type is optional. Choose Team meeting for this example, then choose Facilitator as your role. The app explains the focus: help keeping the meeting on track and closing decisions. Next, look at Documents that help here. Agenda, open decisions, and recent updates are suggestions for useful background. They are not three separate forms you must complete. Use Content to describe the situation, or use Upload a file to supply a document. Include the goal, the people involved, the decisions already made, and what is still open. In our example, the opening date is a target, responsibilities are named, and the second grinder is still an open decision. Keeping these distinctions clear helps you ask more useful questions. Save your context, then check the result. In this desktop flow, creating a context from Chat also selects it. The selected count and the Team meeting, Facilitator banner show which background is active. Check these before you ask your next question; a saved context and an active context are not the same thing. Your question tells the assistant what you need now. Your selected context supplies the background. Review the response against your source before using it.
