Ask questions, delegate tasks to specialized agents, pull context from your knowledge bases, and interact with connected tools — all within a single chat interface. Coworker automatically has access to all the tools and integrations configured in your workspace. ## Key Features Use `@` to mention and delegate tasks to any agent in your organization directly from the chat. Select a knowledge base collection to give Coworker context from your documents and data. Coworker discovers and uses all connected tools and integrations automatically. Search, filter, and revisit past conversations organized by time and agent. ## Getting Started Navigate to **Coworker** in the sidebar. You'll see a welcome screen with: * A chat input where you can type your message or use `@` to mention an agent * **Suggestion cards** showing available agents, workflows, and apps you can interact with * Tabs to filter suggestions by **Favorites**, **All**, or **Agents** Coworker welcome screen with chat input, suggestion cards, and sidebar Type your message and press **Enter** or click the send button to start a conversation.
