Shortwave

What is Shortwave?

Shortwave is an AI-first email client made by a team of ex-Google engineers that automates inbox management, writing, and search through natural language prompts. Available as a freemium service on iOS, Android, Mac, and Windows, it combines traditional email functionality with AI capabilities to reduce time spent on email administration.

The core feature is the Shortwave Agent, an AI assistant that organizes emails, schedules messages, drafts replies, and searches conversations using conversational commands rather than manual sorting. Users can create custom AI filters written in plain English to automatically label, archive, star, or manage emails without coding. The system learns writing patterns from sent emails to generate replies that match individual voice and style. Advanced search functionality lets teams analyze entire email archives and attachments for specific information. Additional capabilities include AI-powered summaries appearing at the top of each email, intelligent autocomplete with personalized suggestions, smart snooze timing, link tracking, read receipts, and scheduled delivery to control when messages arrive.

Integration extends to Slack, Calendar, Notion, Asana, and HubSpot, allowing email automation to trigger workflows across connected platforms. For deeper workflow automation, Shortwave integrates with its sister product Tasklet, which connects to over 3,000 apps. Team collaboration features include shared threads that update in real-time, private commenting within emails, assignable tasks with progress tracking, shared labels creating searchable team archives, and template libraries for common responses.

The interface emphasizes keyboard-first navigation with markdown support and shortcuts. Additional tools include inbox splitting into custom tabs, bundle controls for managing newsletters and promotions, todo conversion transforming emails into action items, and granular push notification controls.
