Last reviewed 2026-06-19

Shortwave is an AI-native email client built on top of Gmail by a team of ex-Google engineers who previously built Google Inbox and Firebase. It rebuilds the inbox experience (bundles, snooze, split inbox) and layers a "Shortwave Agent" that searches your mailbox in natural language, drafts and rewrites replies, summarizes threads, auto-labels via AI-powered filters, and assists with scheduling, all from a single prompt. Founded by Andrew Lee and Jonny Dimond and shipping since around 2022, Shortwave has shifted its positioning from "AI email client" to "automate your email with AI," with an agentic framing for business communications. Email drafting is review-gated (the user approves and sends), so the core is a copilot, while filters and the agent run multi-step actions you configure and observe.
