Shortwave

Best for team collaboration and AI summaries

Shortwave reimagines email as a collaborative workspace with Ghostwriter that learns your unique writing voice and style to generate contextual responses. AI Summaries appear at thread tops, condensing long conversations into key points for quick understanding. Smart Bundles automatically group related emails (e.g., all shipping notifications, newsletters, receipts) enabling 45% faster inbox zero by processing batches instead of individual messages. Tasklet automation connects email to Slack, Calendar, Notion, Asana, and HubSpot using plain English commands—"When I star emails from clients, create Asana tasks" executed without code. The built-in calendar integrates with email context, enabling AI scheduling that understands email discussion context and suggests optimal meeting times. Conflict checking prevents double-booking across calendars. iOS and Android apps provide full functionality mobile. For teams coordinating via email, Shortwave's collaboration features combined with AI assistance create a modern email experience that respects how people actually work together.
