Why Developers Switch from Shortwave

Shortwave is expensive — $24/mo for Business, up to $100/mo per seat for Max. That's $1,200/yr per user. Grip Mail is $99/yr.

All AI processing happens on Shortwave's servers — your email data leaves your device. Grip Mail runs AI on-device via MLX.

No BYOK model choice — you're locked to whatever AI Shortwave provides. Grip Mail lets you choose Claude, GPT, Gemini, or free local inference.

The Mac app is Electron-based, not native SwiftUI. On macOS, native apps are noticeably faster and use less battery.

What Shortwave Does Better

We believe in honest comparisons. Here's where Shortwave genuinely excels.

Shortwave's AI search across 5 years of email history is genuinely powerful — natural language queries that find conversations you forgot about. Grip Mail's search is strong but newer.

Personalized writing and AI filters are mature features refined over years of development.

Read statuses and delivery tracking are useful for sales and client-facing roles. Grip Mail doesn't have these yet.

Cross-platform support (Web, iOS, Android) means Shortwave works everywhere, not just on Mac.
