Overview

Shortwave: AI-Native Email Client for Gmail

Shortwave is AI-native email client built on top of Gmail — does not replace your account, augments it. Shortwave's pitch is that traditional Gmail clients (and even Gmail itself) treat AI as a bolt-on. Shortwave is rebuilt from the ground up assuming AI is the primary interface: every action — triage, draft, search, summarize — runs through AI rather than through pre-AI affordances. Andrew Lee's Firebase credibility and Sequoia backing have made Shortwave the leading AI-native email client for power users.
