Shortwave Overview
Shortwave is an AI-native email client built on top of Gmail by people who worked on Google Inbox, and it shows. Rather than giving you a new mailbox, it connects to your existing Gmail or Google Workspace account and rebuilds the entire experience around speed, AI assistance, and team collaboration. The result feels like what Gmail could have become: a split-tab inbox with bundles, todos, and an assistant that can search years of thread history, draft in your voice, and organize mail with plain-English filters.
An Inbox Built for Triage
The interface is keyboard-first, with a command palette and serious shortcuts for power users: press T to add an email to your to-do list, D to delete, and so on. Split tabs let you view multiple inboxes or searches side by side, while bundles automatically group newsletters and similar mail so you can deal with them in batches. Converting emails into todos, snoozing messages for later, and collapsing threads into task-oriented views makes the inbox behave like a to-do list, which is exactly how many professionals already use email.
AI Assistant and Search
The AI assistant is the headline feature. Semantic search lets you ask natural-language questions over your real thread history — ‘what did we agree on with the client last March?’ — and get grounded answers instead of keyword matches. The free plan limits searchable history to 90 days, while paid tiers extend it to one year, five years, or unlimited. AI summarization condenses long chains in one click, instant smart replies handle routine responses, and the ghostwriter-style drafting learns your writing style from sent mail to produce replies that sound like you. You can even instruct it conversationally: tell it to decline a meeting or accept one and ask for an agenda, and it drafts the appropriate response.
Automation with AI Filters
Shortwave’s filters go beyond Gmail’s rule builder. You describe what you want in plain English — label, star, or archive matching mail — and the AI applies it. This is genuinely useful for taming high-volume inboxes without writing filter syntax. Higher plans add more filters, link tracking, read receipts, and calendar integration, plus multi-account support and custom themes.
Built for Teams
Where Shortwave really differentiates from consumer AI email tools is collaboration. Teams get shared threads, private comments on live emails, shared labels and prompts, and role-based access — effectively turning the inbox into a Slack-like workspace for email. Sister product Tasklet can hook drafts and actions into other apps, and MCP integrations open the door to automation workflows. For support teams and startups where email is a shared responsibility, this is a meaningful upgrade over forwarding threads around.
Platforms and Pricing
Shortwave runs on web, Mac, Windows, iOS, and Android, so your triage workflow follows you across devices. The free plan is a capped demo: basic AI features, 90 days of search history, and the mandatory ‘Sent with Shortwave’ signature. Pro costs $18 per seat per month with deeper AI and longer history. Business at $30 adds team features, read statuses, and AI-powered filters. Premier at $45 extends search to unlimited history with link tracking and an activity feed, and Max at $120 unlocks the top model tier with the highest quotas. Plans mostly bill monthly, and even the top tiers meter daily AI quota.
Where It Falls Short
The hard limit is Gmail-only support. If you use Outlook, iCloud Mail, or juggle multiple providers, Shortwave is simply not an option — Superhuman or a Gmail add-on would be. The free tier’s forced signature makes it embarrassing to use professionally, so realistically you are paying from day one. Daily AI quotas even on expensive plans can surprise heavy users, and per-seat pricing climbs fast for teams. Switching email clients carries a real productivity cost: new shortcuts, new mobile apps, and weeks of retraining muscle memory. Finally, when AI features are enabled, your email content is sent to OpenAI for processing. The company says data is encrypted and not used for training, but it is still another data processor in the loop, which matters for sensitive work email.
Getting Started
Connect your Gmail or Google Workspace account and give Shortwave a few days to index your history — the AI search gets dramatically more useful once it has context. Start with the free plan to learn the keyboard shortcuts and triage flow: practice bundling newsletters, converting emails to todos, and using split tabs before committing to a paid tier. Set up a few plain-English filters for your highest-volume senders, and try asking the assistant a real question about an old thread to feel the semantic search difference. If your team will use it, pilot with two or three people on shared threads before rolling it out — the collaboration features are where the per-seat cost starts paying for itself.
Shortwave vs the Alternatives
Against Superhuman, the other premium Gmail client, Shortwave is cheaper and stronger on AI search and team collaboration, while Superhuman has a longer track record and a famously polished onboarding. Versus staying in Gmail with add-ons, Shortwave demands a full client switch but delivers a fundamentally faster triage experience. Compared with Notion Mail, Shortwave is more mature and cross-platform, while Notion Mail suits Notion-centric users who want a calmer interface. The deciding question is whether you are willing to leave Gmail’s interface behind.
Who Should Use It
Shortwave is the strongest AI email client for people who live in Gmail and want Inbox-era organization plus an assistant that actually understands their history. Start with the free plan to test the split inbox and triage flow, buy Pro when AI search and drafting become daily habits, and consider Business when your team needs shared threads. If you will not change email clients, stay in Gmail and look at add-on tools instead.
