Connects to X (Twitter) and LinkedIn to let you draft, schedule and publish social media posts. Muse can help you compose posts, plan your posting schedule, and manage your social presence across both platforms.

Example request: "Schedule a LinkedIn post about my new product launch for tomorrow at 9am"
