ChargeDetector
One scan. Every forgotten subscription. 30 seconds.
Free, private tool that scans your Gmail export for hidden recurring charges. No account needed. No data stored — everything runs in your browser. Within 30 seconds, you'll see exactly how much money is quietly leaving your account each year, with direct cancellation links for every service found. Think of it as a financial health check for your inbox.
I built ChargeDetector after discovering I was paying $847/year for subscriptions I'd completely forgotten about.
The moment: I was reviewing my credit card statement and spotted three charges I didn't recognize — Adobe CC ($59.99/mo) from a job I left 2 years ago, a streaming service I'd signed up for during a free trial, and a cloud storage plan I'd upgraded and forgotten.
The problem: Most of us have no idea how many subscriptions are quietly leaving our accounts. Banks don't warn you. Services don't remind you. And checking manually across 2+ years of emails is impossible.
The philosophy: I built this to be genuinely private — everything runs in your browser. No servers. No accounts. No data collection. You upload your Gmail export, it scans subject lines only, detects subscriptions, shows you the damage, and deletes everything. That's it.
Tech stack: Next.js + TypeScript, client-side Gmail API, IndexedDB for processing, zero backend.
I'd love to hear what forgotten subscriptions YOU find. Drop your results below — I'll start: my personal worst was Adobe CC at $719.88/year.
