Suprascribe is an Outlook subscription tracker that reads the receipts, billing confirmations, and renewal notices already sitting in your inbox. It connects via Microsoft OAuth and builds your complete subscription list - for free, with no bank access required.
Suprascribe uses the official Microsoft Graph mail API - the same authentication Microsoft uses for Teams and Office add-ins - with read-only access.
Connect Outlook with one click through Microsoft OAuth, using read-only mail permission. Suprascribe never sees your Microsoft password, and access can be revoked at any time from your Microsoft account settings.
The scanner looks for receipts, renewal notices, and billing confirmations - not your personal messages. Unrelated emails are never read or stored.
Outlook.com, Hotmail, Live, and MSN addresses are the same Microsoft mailbox. Connect once and the scan covers the receipts sent to every alias you have collected over the years.
Connect your Outlook account, run the scan, and get a complete subscription list. No manual entry, no bank linking, no credit card required.
Most subscription detection tools - Rocket Money, PocketGuard - require connecting your bank account via Plaid. That means handing over access to your complete transaction history to find subscriptions.
Suprascribe takes a narrower approach: every subscription generates an email receipt. Scanning those receipts produces the same result - a complete subscription list - without touching your bank account at all. Your financial data stays between you and your bank.
The Outlook scanner finds emails matching subscription patterns, then reads their subject, sender and body so the billing details can be extracted. No email content is stored. The scan is ephemeral - only the extracted subscription name, amount, and renewal date are saved.
