What is BillSensor?
BillSensor is a free Chrome extension that detects SaaS billing emails as you browse Gmail and alerts you 7 days before renewal charges. No Gmail OAuth, no bank connection required. Tracks 62+ SaaS tools, shows a dark pattern score for each, and provides direct cancel links. Free plan includes unlimited passive detection and Chrome alerts. Pro adds email alerts, cloud sync, and cancellation records.
What it solves
- SaaS free trials convert to paid plans silently, with no warning before the charge hits
- Cancellation flows are deliberately confusing, making it easy to think you've cancelled
- Some tools keep charging even after you've cancelled, with no easy way to catch it
- Tracking multiple subscriptions manually across emails and bank statements is tedious
How it works
- Passively reads Gmail as you browse, no OAuth connection or Gmail account access required
- Detects billing emails from 62+ SaaS tools and logs each subscription automatically
- Fires a notification 7 days before the next renewal charge, giving you time to cancel
- Shows a dark pattern score for every detected tool, so you know exactly how hard to cancel
