Promise
Track what you owe, what you're waiting for, and what you need to remember.
Promise connects to your email and other sources to build a memory of commitments you've made, follow-ups you need to do, and things you're waiting on. Muse can show you what needs attention today, search your memory, and help you capture and mark items complete.
Try asking Muse: "Show me what I promised to do this week and who I'm waiting to hear back from."
