Your inbox is running your business. Badly.

📧

You write 80+ emails a day

It takes 3 hours. That's 3 hours you're not building, selling, or shipping.

🤦

You forgot to follow up

And lost a $20K deal. Not because you're bad at your job — because your inbox doesn't track promises.

💸

$600/year in subscriptions

You don't use half of them. Price increases happen via email. No one's watching.

You don't need a new email app. You need a copilot in the one you already use.

SETUP 30 seconds. Seriously.

Set up in 30 seconds. Seriously.

No new app to learn. No data to migrate. No emails to forward. Just Gmail, but with superpowers.

AI never reads your email. Unless something's actually dangerous.

Local heuristics scan every email — no AI, no API calls, nothing leaves your browser. AI only kicks in on real threats (risk score 40+). Your normal emails are never touched.

Two-Tier Security Architecture

Quick Scan runs locally on every email. Deep Scan (AI) only fires on confirmed threats.

✓ Quick Scan: local heuristics, zero API calls
✓ Deep Scan: AI analysis on threats only (risk 40+)
✓ Brand impersonation detection
✓ Homograph attack prevention (PayPal vs PayPaI)

Privacy by Architecture

Not "we promise we don't read your emails." The architecture makes it impossible.

✓ 100% local processing — nothing leaves your browser
✓ No email storage on any server
✓ SPF/DKIM/DMARC forensics
✓ Pre-click link blocking on suspicious emails

ORIGIN Built by a founder who was drowning in email

Why I built SuperMail.

I was running my business from Gmail — 150+ emails a day. I tried Superhuman ($30/month to read email faster?). I tried every AI tool (they all wanted to read my emails). Nothing worked.

So I built SuperMail. An AI copilot that lives in Gmail, tracks my promises, catches scams, saves me money on bills, and never stores a single email on a server.

I built the tool I wished existed. Now I'm sharing it with other founders who feel the same way.
