I finally built Omnia OS because my inbox turned into a landfill of AI-generated noise. If you're going to email me going forward, I suggest including a more compelling subject and opening line, otherwise all emails from unknown people will not make it to my inbox. AI draft-suggestion tools never solved the real problem: finding the messages, files, or company I actually need to follow up with. After securing AI systems for a living, I know how easy it is to weaponize prompt injection, so bolting AI onto email without redesigning the core experience felt reckless. First, we need to separate trusted from untrusted senders, then decide whatever touches automation.
Omnia OS is the email client I now rely on: New senders/orgs are isolated until you approve them, so domain spoofing means you will not make it to the inbox anymore, because it will be isolated as a new organization that needs approval.
Catch-up view shows everything that happened since you last checked:
- meetings, threads, urgent items.
- Every company you work with has its own space for contact lists, file management, and basic company intel, so you stop searching through old chains.
- Mass unsubscribe and delete emails
Coming back to work on Monday or a long weekend used to take half a day reviewing emails. Now you see what matters, act, and move on.
It's free to use as a desktop app for your email client on MacOS.

*Since this is my side project, the initial build only supports MacOS and Gmail. Happy to collaborate on new capabilities.
