Email hasn't evolved in a decade. signet is a user-centered, agent-enabled, multi-account email system built for how people actually work now — several identities, constant context switching, and an agent that drafts alongside you instead of narrating at you.
01
Multi-account, first-class. Most of us run three or four identities — work, side project, personal, a board seat. signet treats each as equal: one inbox, coded pills, and a composer that can't send from the wrong account.
02
Agent-enabled, not agent-narrated. The agent reads threads, drafts replies, and extracts the decision you actually have to make. You approve with Y, reject with N, edit with E. No “AI is thinking…” chrome.
03
User-centered, not feature-centered. Five GTD tabs, a compact 56px row, and one keyboard shortcut per action. We took things away until the inbox matched how you actually triage.
04
Built for 2026, not 2014. Email hasn’t meaningfully changed in a decade. signet is a ground-up rewrite around the constraints of today — agents, multiple identities, and people who live in their inbox.
