Partial The web client, keyboard shortcuts, and AI triage and drafting are buildable on Gmail and Outlook APIs, but reliable multi-account sync, native Mac, Windows, and iPhone apps, and offline support are substantial engineering that vibe coding alone won't reliably deliver.
What it would actually take: A real version would combine a web client (for example React/Next.js) with a sync layer that caches mail from the Gmail and Microsoft Graph APIs and handles push notifications, threading, and search. Native clients need Swift and Electron or Tauri work with local storage. The hard parts are sync correctness at scale, the security and OAuth review required by Google and Microsoft, and maintaining several platform clients.
