Your inbox is encrypted.
It still runs your morning.
Canary Mail promises PGP encryption and cloud AI in the same app. Swizero is honest about the two layers: ranking on-device, summaries via zero-retention cloud. And then it does something Canary never tries: it lets you finish.
Canary sells PGP encryption and cloud AI features in the same app. One promises your data never leaves. The other requires that it does. Swizero is honest about the split: ranking stays on your phone, summaries use zero-retention cloud. Then it does something else entirely: it lets you finish.
Secure but always on
PGP encryption. HIPAA compliance. AI summaries. Smart prioritization. Canary promises all of these in one app. But PGP means your data stays local, while AI summaries require cloud processing. Which is it? Your emails are private, or your emails are processed by AI on a server? The lock is real. The contradiction is also real. And either way, you still check constantly.
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 it empty. When it is gone, email is done. Not a more secure inbox. A finished one. You close the app and walk away.
Feature-by-feature comparison
Not just checkmarks. Context on what each feature actually means for your daily workflow.
How it works
Canary secured the inbox. Swizero replaced it with a session that ends.
What done looks like
Canary protects your data. Swizero protects your morning.
Privacy approach
Swizero is upfront about what happens where. Canary blends encryption claims with cloud-dependent features.
AI email ranking
Swizero's ranking never leaves your phone. Canary's prioritization requires cloud processing.
AI summaries
Both summarize via cloud AI. Swizero guarantees zero retention. Canary's retention policies are less explicit.
AI drafts
Both draft via cloud AI. Both require your data to leave the device for this feature.
Bulk unsubscribe
Canary helps you unsubscribe from lists. Swizero simply never surfaces junk in your stack.
Email encryption
Canary's PGP encryption is genuine for securing email content in transit. If you need PGP, Canary delivers.
HIPAA compliance
Healthcare professionals handling PHI should consider Canary's HIPAA support.
AI data handling
This is the tension: Canary's AI features require the same cloud processing its encryption story implies you avoid.
Ranking intelligence
Another contradiction: Canary's smart prioritization sends your email patterns to a server, despite the encryption positioning.
Mobile app
Canary covers both mobile platforms today.
Desktop app
Canary has full cross-platform coverage.
Email providers
Canary supports nearly every email provider out of the box.
Monthly price
Canary is cheaper as a feature client. Swizero costs more because it replaces your triage workflow, not just your mail app.
Free tier
Canary's free tier works for basic email. Swizero is free during beta, then $6.67/mo annually.
Session model
The core difference: Swizero is built for sessions that finish. Canary is an always-available inbox.

A morning with each app
Same person. Same 94 unread emails. Two different experiences.
Open Canary Mail. The inbox loads with 94 unread emails. The lock icon gives you a sense of security.
Private, sure. But 94 emails is still 94 emails.
AI summaries help you skim. Smart prioritization surfaces a few important threads. You start reading.
Reply to a client. Use AI compose to draft a response. Check the encrypted badge, feel good about that.
Ten minutes in. The lock icon is reassuring but it does not make the pile smaller.
Still scrolling. Bulk-unsubscribe a few newsletters. Delete some promotions. 38 emails left to process.
This is taking a while.
Get through most of it. Close the app. But you know you will open it again before lunch.
Notification. Open Canary again. 7 new emails. Start the cycle again.
Your data is safe. Your morning is gone. Canary protected one and forgot about the other.
33 minutes across two sessions. Inbox is secure. But you opened it twice before 9 AM.
Open Swizero before coffee. Same 94 emails. AI ranked them on-device overnight. The ranking model never left your phone. Cloud AI processed summaries and drafts with zero retention. You know exactly what happened where.
Private and transparent. No tension between the two.
First card: a sensitive work thread. One-line summary gives you the gist without opening the full email. AI draft is ready. You review it, adjust one line, swipe up to send.
Your email content was processed, never stored. That is the guarantee.
Promotional emails, newsletters, and subscription receipts? The AI filtered them out before you woke up. No bulk unsubscribe session needed. They simply never reached the stack.
Two more cards. A team update you swipe down to archive. A personal email you swipe right to flag for tonight. Stack is empty.
Five minutes. Private the whole time. And now you are free. That is what Canary never offered: an ending.
Close the app. No notification will pull you back. No lock icon on an inbox you still check constantly. The session ended. Your data stayed private. Both things can be true at once.
Private and done. Your data stayed safe and your morning stayed yours.
6 minutes. Zero-retention privacy. On-device ranking. And the thing Canary never offered: a reason to close the app.

Migrating from Canary Mail, step by step
The exact steps, the real time it takes, and the honest reasons you might keep Canary.
- 1
Keep Canary installed
0 secDo not uninstall anything. Nothing here touches Canary, your licence, or your mailbox. If you use Canary for PGP threads, you should keep it either way.
- 2
Install Swizero on iOS
1 minJoin the beta and add the app from your invite. It is built mobile-first for one-handed use, so there is nothing to set up on a Mac or a PC.
- 3
Connect your Gmail
30 secSign in with Google through secure OAuth. Swizero ranks your mail on-device, and your labels, filters, and full history stay in Gmail exactly where they are.
- 4
Swipe your first stack
2 minSwizero ranks your inbox and hands you a fixed card limit. Swipe left to clear, down to archive, right to flag, up to reply. Most people finish their first stack in minutes.
- 5
Run both for a couple of weeks
Use Swizero for the daily triage and keep Canary for anything that needs PGP, a non-Gmail account, or a desktop. They do different jobs, and running both is a perfectly sensible end state.
- 6
Drop Canary only if it stops earning its place
If you bought a lifetime licence there is nothing to cancel, and it costs you nothing to leave installed. If you are on Growth or Pro+ you can simply let the year run out. Nothing was migrated or deleted, so switching back is instant.
Where Canary Mail is the better choice
We are not going to pretend Canary has no edge. On several things it is simply ahead of us, and here they are.
Real PGP end-to-end encryption
Canary has genuine PGP support with key management built into the app. If you exchange encrypted mail with anyone, Swizero cannot do this and is not planning to fake it.
It runs on everything
A single Canary licence covers macOS, iOS, Windows, and Android. Swizero is iOS-first, with desktop still to come.
Every provider in one app
Gmail, Outlook, iCloud, Yahoo, and plain IMAP all work in Canary, with several accounts side by side. Swizero starts on Gmail, with Outlook planned.
A free tier and a lifetime option
Canary's free plan covers core mail on up to two devices, and both Growth and Pro+ can be bought outright as one-time lifetime licences. Swizero is subscription only.
Canary Mail plans and prices (a free tier for up to 2 devices, Growth at $3/mo billed yearly at $36/yr, and Pro+ at $10/mo billed yearly at $100/yr, both also sold as one-time lifetime licences, with a single licence covering macOS, iOS, Windows, and Android) as published on canarymail.io, last checked July 2026. Swizero launch scope reflects the current iOS beta.

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.
Keep Canary for PGP
If you need PGP encryption for specific contacts, keep Canary for those threads. Use Swizero for your daily triage. They complement each other.
From inbox to stack
Instead of scrolling a traditional inbox with a lock icon, you swipe through a ranked stack. Most people adapt in one session.
From always checking to actually done
The biggest shift: you stop refreshing an encrypted inbox all day and start experiencing the calm of a stack that empties. Private and finished.
Honest privacy model
No tension between encryption claims and cloud AI. Swizero tells you exactly what runs on-device and what uses zero-retention cloud.
Your mornings back
When email actually ends, you reclaim the 20-40 minutes per day you spent re-checking a secure inbox that still never told you when to stop.
“I picked Canary for the encryption. Swizero surprised me because I stopped checking constantly. Five minutes and I close the app. Privacy matters, but so does my morning.”
