Shortwave
AI email client for Gmail
A modern Gmail replacement with AI summaries, an assistant, and bundling. If you're on Gmail and want a new inbox app, Shortwave is a strong option.
Syve vs Shortwave
Both tools apply AI to your email. The biggest practical difference: Shortwave replaces your Gmail client. Syve sits on top of Microsoft 365 or Outlook.com and hands you a strategy-ranked briefing without changing where you read email.
Syve
Strategy assistant for Outlook / M365
Not a new email client. Syve keeps you in Outlook and delivers a morning briefing ranked against a strategy doc you upload, plus drafted replies, a meeting audit, and an end-of-day recap.

When to pick which
Pick Shortwave if you're on Gmail and want a smarter inbox app. Pick Syve if you're on Outlook or Microsoft 365 and the real question isn't "how do I read email faster" but "which of these threads actually move my quarter forward, and can something else handle the rest?"
