Shortwave added AI to an infinite feed.
You still open it dozens of times a day.
Shortwave made your inbox smarter. Swizero asks a different question: what if your inbox could be finished? A ranked stack you swipe through in minutes, then close.
Shortwave is not the problem. It is brilliant software. The problem is that brilliant software keeps you inside your inbox. What if the answer is not a smarter inbox, but a shorter one?
The AI-powered feed
AI search. Chat with your email. Auto-labels. Smart summaries. Every feature makes your inbox more powerful, more engaging, more worth checking. The smarter it gets, the harder it is to close. You came for AI help. You stayed for over an hour.
A stack you finish
AI ranks your email by importance and presents only the ones that matter as swipeable cards. You swipe through the stack and watch each card disappear. When it is empty, email is done. Not surfaced, not optimized. Done as in close the app and walk away.

A morning with each app
Same person. Same 83 unread emails. Two different experiences.
Open Shortwave. AI has organized overnight emails into smart categories. 83 unread across labels.
Organized. But how long will this take?
Check the AI briefing. It summarizes a stack of threads. Tap into three that look important.
Use AI search to find that contract from last week. Ask a follow-up question in chat. Get a useful answer.
Impressive. But you have been in the app for 9 minutes now.
Start composing replies. AI suggests drafts. Tweak tone. Send four responses.
Notice the AI surfaced a thread you missed. Read it. That leads to two more threads. Open those too.
Wait, I thought I was almost done.
Slack notification pulls you to a team channel in Shortwave. Respond to three messages.
Finally close the app. But the AI briefing badge says '5 new insights.' Open it again.
The AI keeps finding things to show you.
Check again on the web. New categorized emails. The feed refreshed.
When does this actually end?
Over an hour across three sessions. Inbox is organized. But the AI keeps surfacing more.
Open Swizero. The same 83 emails ran through AI overnight. But instead of surfacing all of them with insights, it filtered down to the ones that actually need you.
Quiet. Intentionally quiet.
First card has a one-line summary. No chat sidebar. No follow-up threads to explore. Just one question: act on this, or move on? Swipe left to delete.
Client follow-up. AI draft is already written. You review it, swap one phrase, swipe up to send. No tone sliders, no length controls. Just a good draft.
The AI helped without pulling you deeper in.
Two more cards. A team update you swipe down to archive. A billing notice you swipe left to delete.
Stack is empty. No AI briefing badge. No '5 new insights' notification. The app has nothing more to show you.
The calm of actually being done. No AI badge pulling you back. Just quiet.
Close the app. Phone goes in your pocket. You walk away from email and forget about it. There is nothing new to discover, nothing the AI is about to surface.
7 minutes. The AI showed you less, not more. No briefing badge. No pull-back. Inbox closed.

Switching from Shortwave takes 2 minutes
What you keep, what changes, and what gets better.
Your Gmail stays untouched
Swizero connects via secure OAuth. Your existing labels, filters, and email history remain exactly where they are.
Your Shortwave labels carry over
Any labels or organization you built in Shortwave live in Gmail. They stay. Swizero reads them too.
From AI chat to a ranked stack
Instead of chatting with your inbox, you swipe through the emails that matter. Most people adapt in one session.
From exploring to finishing
The biggest shift: you stop discovering more and start experiencing the relief of done. The AI shows you less, not more.
Simpler, more honest pricing
$9.99/mo for everything. No tiers, no feature gates, no upsells. Shortwave's comparable tier costs nearly 2x more.
Your mornings back
When email actually ends, you get back the 30-50 minutes per day Shortwave's AI kept filling with more insights, more threads, more reasons to stay.
“Shortwave is genuinely impressive software. But I was in the app for an hour every morning. Swizero gets me through email in minutes. Turns out I wanted less, not more.”
