what you're actually comparing

Superhuman is a premium email client built on top of Gmail and Outlook. It's famous for two things: a keyboard-first design that makes email fast, and a price that filters for serious users. It was acquired by Grammarly, and Superhuman Mail now sits alongside Grammarly's wider suite — Mail starts at $30/month monthly or $25 annually, with a Business tier at $40/$33 that bundles the rest. When it launched, it felt like the first email client that took speed seriously.

Shortwave is a Gmail-native email client with AI as the primary feature. Built by ex-Googlers, it focuses on AI-powered triage — summarizing threads, bundling related emails, drafting replies, and surfacing what actually needs your attention.

Both are selling the same promise: email that doesn't consume your day. Their methods are different.

where shortwave wins

AI that's actually useful. Thread summaries are Shortwave's best feature. If you come back from a three-day vacation to a 45-email thread, Shortwave gives you a two-paragraph summary before you read a single message. Superhuman's AI features are newer and less integrated.

Price — but check the direction. This used to read $9/month vs $30/month in Shortwave's favour. It no longer does: Shortwave starts at $30/seat and runs to $120, while Superhuman is $30 monthly or $25 annually. If you are choosing on price today, Superhuman wins, and the gap widens if you were considering Shortwave's higher tiers.

AI drafting. Shortwave's reply drafting learns your writing style over time. Drafts that need minimal editing. Superhuman has AI drafting too, but Shortwave's feels more like your own voice.

Gmail integration depth. Shortwave was built by ex-Google engineers and integrates with Gmail's infrastructure directly, not through a sync layer. Labels, filters, and Gmail-specific features all work as expected.

Bundling. Shortwave's automatic email bundling — grouping newsletters, notifications, and conversations together — is a different way of organizing your inbox that some people find significantly better than a flat inbox.

where superhuman wins

Keyboard speed. Superhuman's keyboard shortcut system is the most complete of any email client. Every action has a shortcut, the search is instant, and the muscle memory for power users is genuinely faster than any other email client. If you process hundreds of emails daily by keyboard, this matters.

Social features. Superhuman's read receipts, send later with reminders if no reply, and the social graph (who you email most) are features that power users build workflows around. Shortwave doesn't have equivalents.

Multi-provider. Superhuman supports Gmail, Google Workspace, and Outlook/Exchange. If your team uses different email providers, Superhuman can handle both. Shortwave is Gmail-only.

Polish. Superhuman has been refining a narrow set of features for years. The animation, the attention to interaction detail, and the feeling of a premium product are real. At $25–30/month, the product quality reflects the price — and it is now being compared against a rival that costs the same or more.

Team features. Superhuman's team inbox sharing and comment threading on emails has some enterprise use cases that Shortwave doesn't match.

things to know

Superhuman requires application. As of its early years, you needed to request access and sometimes do an onboarding call. This may have changed, but the exclusivity was part of the positioning.

Neither replaces Gmail's web app entirely. Both clients are layers on top of Gmail. If someone sends you a Google Doc and you click it, you're in a browser. Some features require falling back to Gmail.com.

Shortwave is still maturing. Shortwave is younger than Superhuman. Some features feel less refined. If you try it and something feels rough, it might be fixed in a few months.

The real alternative. For many people, the best email client is just Gmail with some habits — unsubscribe aggressively, use labels, check twice a day. Paid email clients don't fix the volume problem; they make processing it more bearable.
