Shortwave is the most AI-native email client around, but it is Gmail-only and replaces your inbox. Pidgy works in both Outlook and Gmail, chases stalled follow-ups, and groups email into projects.
Shortwave and Pidgy both lean hard on AI, but Shortwave is a Gmail-only client you switch to, with standout AI search. Pidgy layers onto both Outlook and Gmail, ranks the few emails that need you, chases stalled follow-ups, and groups email into projects with one Inbox Health score. Pick Shortwave if you are Gmail-only and want the most AI-native client. Pick Pidgy if you need Outlook, or want the work organised after triage.

The table shows what each does. Here is why the differences matter.
Shortwave does not support Outlook or IMAP. If any part of your work lives in Outlook, it is a hard stop.
Pidgy reads Outlook and Gmail as one inbox, with a single ranked list across both. For Microsoft users or mixed stacks, that is the difference.
Shortwave is brilliant at finding and drafting, but it does not watch your threads for the ones that stalled, and it does not turn email into tasks or projects.
Pidgy chases stalled follow-ups on its own, groups email into projects, and rolls it into one Inbox Health score, so nothing slips after triage.
Built by ex-Google Inbox engineers, Shortwave has the most polished AI-native experience and the best AI search in the category. If you are Gmail-only, it is a joy.
Pidgy searches your email, but Shortwave's AI search is its signature. If that is your main need and Gmail is your only inbox, Shortwave is a strong pick.
Shortwave replaces your client, and its thread-bundle interface takes a few days to adjust to.
Pidgy works on top of your existing inbox, so you keep Outlook or Gmail exactly as they are.
Both are good tools. They solve different problems.
The one built to close the loop, across Outlook and Gmail.
