About Shortwave

Shortwave is the AI-native email client built on top of Gmail. Its standout Ghostwriter feature analyzes your sent mail to learn your tone, word choice, and signature phrases, then drafts replies that sound authentically like you. AI search lets you ask ‘what did Sarah say about the Q3 budget?’ and Shortwave finds and summarizes the answer. The new Tasklet platform (Oct 2025) connects email to Slack, Notion, Asana, and HubSpot. Free for personal Gmail; Business at $9/user/mo; Pro at $14/mo annual.
