BillSensor efficiently tracks SaaS subscriptions by automatically identifying billing emails and notifying users ahead of renewal fees. It is compatible with both Gmail and Outlook platforms. For users of Gmail, the detection process is seamless, as billing emails are accessed in real-time upon inbox viewing, requiring no connection to a Google account, no OAuth permissions, and no initial setup—simply install the extension and it becomes operational instantly. For those using Outlook or Microsoft 365, a single read-only connection via the extension's popup allows for a quick scan of the past year’s billing history, revealing all active subscriptions, including those that might have been overlooked. Each identified subscription is evaluated on a scale from 1 to 10, reflecting problematic billing practices—this includes how difficult it is to cancel the service, whether fees are incurred post-cancellation, and if the service implements silent upgrades or adds seats without user approval. This comprehensive scoring system helps users make informed decisions about their subscriptions.
