Canary Mail vs Shortwave
A side-by-side editorial comparison of Canary Mail and Shortwave — release velocity, themes, recent moves, and the top alternatives to consider.
Canary Mail vs Shortwave: at a glance
What is Canary Mail?
Canary Mail ships AI chat history while sustaining a cross-platform bug fix cadence.
Canary Mail is a privacy-focused email client holding its position through steady maintenance releases across iOS, macOS, Android, and Windows. The bulk of recent updates are stability patches, crash fixes, and platform compatibility work. The 5.23.0 release added AI chat history and conversation management — the first substantive AI UX feature in several release cycles.
What is Shortwave?
Shortwave keeps folding autonomy into the inbox, one AI action at a time.
Shortwave has moved decisively from an AI-assisted email client to an inbox that acts on the user's behalf. The assistant reads, drafts, organizes, and — via the Tasklet integration — triggers automated workflows across thousands of apps, with its work surfaced inside Shortwave rather than buried in Gmail. Every release since late 2024 has pushed more of the email workflow out of the user's hands and into the model's.
Canary Mail vs Shortwave: editorial side-by-side
Canary Mail
5.0COMMS
Canary Mail ships AI chat history while sustaining a cross-platform bug fix cadence.
◆ Current state
Canary Mail is a privacy-focused email client holding its position through steady maintenance releases across iOS, macOS, Android, and Windows. The bulk of recent updates are stability patches, crash fixes, and platform compatibility work. The 5.23.0 release added AI chat history and conversation management — the first substantive AI UX feature in several release cycles.
◆ Where it's heading
The product is not on a sharp new trajectory. It is consolidating its cross-platform presence, patching legacy issues (PGP decryption, SMTP overwrite, iPad rendering), and iterating slowly on its AI assistant layer. OS 27 compatibility across both iOS and macOS ships promptly, signaling that platform parity remains a priority. AI chat features are being built out one small piece at a time.
◆ Prediction
The next likely move is additional AI chat improvements — conversation search, export, or deeper email-context integration — following the 5.23.0 pattern. Platform compatibility with OS update cycles will continue consuming engineering bandwidth alongside feature work.
Shortwave
0.0COMMS
Shortwave keeps folding autonomy into the inbox, one AI action at a time.
◆ Current state
Shortwave has moved decisively from an AI-assisted email client to an inbox that acts on the user's behalf. The assistant reads, drafts, organizes, and — via the Tasklet integration — triggers automated workflows across thousands of apps, with its work surfaced inside Shortwave rather than buried in Gmail. Every release since late 2024 has pushed more of the email workflow out of the user's hands and into the model's.
◆ Where it's heading
The direction is a steadily widening action surface: MCP connectors to external tools, AI Memories, voice, and now trigger-based automation all frame email as an agent runtime rather than a reading pane. Model choices track the frontier closely — Claude 3.7 to Sonnet 4 to the 4.6 family — keeping capability tied to whatever the best available model can do. The team ships broadly across web, desktop, iOS, and Android each cycle.
◆ Prediction
The next moves most likely deepen autonomous execution — more trigger types and tighter loops where the assistant acts with less confirmation — rather than adding new surface features.
