Superhuman vs Shortwave vs alfred_ — February 2026
What Is Superhuman?
Superhuman launched in 2014 with a waiting list that became legendary in productivity circles, promising the world’s fastest email experience. It delivers on that promise. Superhuman connects to your Gmail or Outlook account and replaces the native interface with one built around speed: every action has a keyboard shortcut, the split inbox separates important messages from everything else, and the interface is visually stripped of anything that creates friction.
Superhuman costs $30/month ($25/month billed annually). There is no free plan. The price reflects its positioning as a premium tool for professionals who process high volumes of email and see the time investment as clearly worth it. Superhuman AI — included in the subscription — drafts replies in your voice, suggests responses, and auto-labels incoming messages based on patterns it learns from your behavior.
What Is Shortwave?
Shortwave is backed by Google and built by the team that previously built Inbox by Google (a beloved Gmail client that Google discontinued in 2019). It connects exclusively to Gmail and reimagines the inbox around AI organization rather than speed. Shortwave groups email into smart bundles (like Inbox did), surfaces AI-generated conversation summaries at the top of threads, and provides powerful natural language search across your entire email history.
Shortwave has a generous free plan. Personal Pro is $9/month ($7/month annual) and adds unlimited AI summaries, priority support, and early features. Teams plans start at $29/month and add shared inboxes, team channels, and collaboration features. For Gmail users who want AI email organization without Superhuman’s price, Shortwave is a compelling option.
Superhuman vs Shortwave: Key Differences
Superhuman's philosophy:
Email is a bottleneck, and speed is the solution. The fastest email client removes every millisecond of friction — every extra click, every mouse movement, every loading delay. Process your inbox faster, then get back to real work.
Shortwave's philosophy:
Email is disorganized, and AI organization is the solution. Smart bundling, summaries, and intelligent search mean you spend less time hunting through your inbox and more time acting on what matters.
The core philosophical difference produces completely different products. Superhuman makes every interaction with your inbox faster — you’re still reading, prioritizing, and responding to every message, but you’re doing it more efficiently. Shortwave makes your inbox less overwhelming — you see bundles instead of individual messages, summaries instead of full threads, and AI-powered organization instead of manual label systems.
On price, the gap is significant: Superhuman at $30/month is more than three times the cost of Shortwave at $9/month. Superhuman also works with both Gmail and Outlook, which is a meaningful advantage for professionals using Microsoft 365. Shortwave is Gmail-only — if you’re on Outlook, the decision is made for you.
The shared limitation of both tools is that they make you better at processing email, but they don’t remove the requirement to process it. You still read every message. You still decide what needs a response. You still manually create tasks from action items buried in threads. You still deal with the calendar conflicts that show up as email requests. Both tools improve the email experience significantly — but neither automates the judgment layer.
- No autonomous triage: Both tools help you process email faster, but you still read and decide on every message
- No task extraction: Neither pulls action items from email threads into a task list automatically
- No follow-up tracking: If someone owes you a reply, both tools require manual reminders or snooze management
- No calendar management: Meeting requests and schedule conflicts are surfaced but not handled autonomously
- No daily briefing: Neither synthesizes your email, tasks, and calendar into a morning briefing of what matters most
When to Choose Superhuman
When to Choose Shortwave
The Third Option: alfred_
If the real problem isn’t email speed or email organization but the volume of judgment email demands — alfred_ ($24.99/month) takes a fundamentally different approach. Rather than giving you a faster or better-organized inbox to process yourself, alfred_ processes it for you. It triages every incoming message, identifies what genuinely requires your attention, drafts replies in your voice for emails that need a response, extracts action items from threads and adds them to your task list, and delivers a morning briefing of what matters most that day.
alfred_ works with both Gmail and Outlook, costs $24.99/month (less than Superhuman), and also handles calendar management: detecting conflicts, preparing meeting context, and managing scheduling requests. For individual professionals who spend meaningful time on email every day and want that time back, alfred_ goes beyond what either Superhuman or Shortwave offers. 30-day free trial.
Our Verdict
Superhuman for email speed; Shortwave for AI organization; alfred_ for autonomous inbox management.
Superhuman and Shortwave are both excellent AI email clients, but they serve different users and solve different problems. Superhuman is the premium choice for professionals who want to be dramatically faster at processing their inbox and are willing to pay $30/month for that experience — especially valuable for Gmail and Outlook users who live in their inbox. Shortwave is the smart choice for Gmail users who want AI organization, conversation summaries, and powerful search at a much lower price point. Both tools make you better at email. alfred_ at $24.99/month takes the next step: removing most of the processing burden by handling triage, draft replies, task extraction, and calendar management autonomously — so you spend time on decisions, not administration.
