Shortwave

Shortwave, built by Shortwave Communications (founded by ex-Google employees), is an AI-powered email client that automates inbox organization, drafts replies in your own voice, and answers questions by searching across your email and attachments. Who it's for: people dealing with high email volume — split inboxes, custom AI filters, and bundle triage are aimed at anyone who wants their inbox actively organized rather than manually sorted — and teams that want shared email visibility (shared threads, private internal comments, task assignment) without switching to a separate helpdesk tool. Strengths: the AI writing assistant is trained on how you personally write, not a generic tone, and its search is built to answer questions across your email history and attachments rather than just keyword-matching subject lines. Native integrations with Slack, Calendar, Notion, Asana, HubSpot, and 3,000+ other apps mean it can sit at the center of a real workflow instead of being an isolated inbox. Weaknesses and limitations: giving an AI tool broad read/write access to an email account is a real trust decision worth thinking through, and switching your primary email client is a genuine workflow disruption, not a lightweight trial. Exact paid-tier pricing isn't shown on the main site — only that a free tier exists — so real cost needs checking on Shortwave's own pricing page. Real-world scenario: someone drowning in a shared team inbox wants messages auto-organized and routed, common replies drafted automatically in their own voice, and the ability to ask "what did the client say about the contract deadline" instead of manually searching threads.
