Shortwave

Shortwave is an AI-native email client that sits on top of Gmail and reimagines it around bundled threads, conversations and an AI assistant. Its assistant can summarize long threads, draft replies in the user's voice, schedule meetings via natural language, search across all email with semantic search, and answer questions like 'when did we last talk to this customer?'. Shortwave supports custom AI agents that automate recurring workflows, plus features like Send Later, snoozing, split inbox, reminders and shared inboxes for teams. It works on web, macOS, iOS and Android and integrates with Google Calendar and Notion. The product targets founders, sales teams and busy professionals who want a faster, AI-augmented email experience without leaving Gmail.
