Triages your inbox by urgency and importance, drafts replies in your voice, unsubscribes from noise, tracks emails waiting for replies, detects important threads buried in clutter, and produces a daily email briefing so you never miss what matters. Designed for professionals, founders, and anyone drowning in email who wants their agent to handle the operational layer of their inbox without losing control of what gets sent.
