Scan your inbox for hidden subscriptions in 30 seconds

Hey hunters! Launching ChargeDetector tomorrow morning. Here's the story:

A few months ago I discovered I'd been paying for Adobe Creative Cloud for 18 months after leaving my job. That's $1,079 I'll never get back. So I manually searched my Gmail receipts took over an hour and found 7 other forgotten subscriptions totaling $1,795/year.

I built ChargeDetector to make this take 30 seconds instead of an afternoon.

What it does:
