Shortwave

Shortwave is an email client built around an AI agent. It connects to your mailbox and handles organizing, writing, searching and scheduling from a plain language prompt, so routine triage and drafting happen inside the inbox rather than in a separate chat window. It runs on iOS, Android, Mac and Windows. It is aimed at professionals and teams who live in email. The agent identifies important messages and todos, sweeps the rest, and applies custom filters written in plain English that label, star or archive automatically. It learns your voice from messages you have sent so drafts read like you, offers autocomplete drawn from your own history, and answers questions by searching across your team's messages and attachments. It checks availability, creates calendar events and writes scheduling mail. Integrations reach Slack, Calendar, Notion, Asana and HubSpot, either natively or over MCP, and the agent can browse the web and analyze PDF, text and code attachments. Collaboration features include shared live threads, private comments on messages, assigned owners with a team wide done status and shared, searchable labels. Pricing is published per seat per month and starts with a 14 day free trial. Business costs $30 and provides standard intelligence, five years of AI search history, up to 50 threads per AI search and three AI filters. Premier costs $45 and adds advanced intelligence, twice the AI usage, unlimited search history, 100 threads per search and ten filters. Max costs $120 and adds expert intelligence, six times the usage, 150 threads per search and 50 filters. The company also operates a sister product, Tasklet, for continuous workflow automation, which Shortwave integrates with for automatic reply drafting and connections to other applications.
