Both tools want to save you time in your inbox. They solve very different problems and, for most people we talk to, they're not really competitors — they answer to different buyers.
A keyboard-first email client built primarily for Gmail (with Outlook support added more recently). Optimized for the person who lives in their inbox all day and wants to move through it faster. Shortcuts, snippets, snooze, split inbox.
An AI assistant for Microsoft 365 and Outlook.com that ranks your inbox and calendar against a strategy or OKR document you upload. Optimized for the person who doesn't want to live in their inbox — who wants a briefing, drafted replies, and a plan for the day.

If you love your inbox and want to fly through it faster with the best keyboard experience on Gmail, Superhuman is excellent. If your problem isn't speed — it's that your inbox and calendar are drifting out of sync with what your quarter is supposed to be about — Syve is built for you.
