PennyGuard is an AI wallet assistant designed to help people understand recurring spending and make better use of their card benefits. The service is preparing to launch and invites users to join its early-access list. Customers can connect a card or bank account through Plaid and optionally link email to build a fuller picture of their transactions. PennyGuard identifies subscriptions, recurring bills, duplicate charges, bill increases, and introductory offers nearing renewal. It also displays cashback and perks that a customer’s card may already provide, along with applicable conditions, and estimates how much remains available to spend after committed expenses.

When users confirm an action, PennyGuard can help cancel supported services, pursue refunds, or seek lower bills. It supports more than 1,000 major US billers, as well as Apple and Google; some cancellations require users to follow instructions themselves. Bank connections are read-only: PennyGuard says it cannot move money or access bank login details. Membership is paid, with pricing shown before charging, and can be canceled in the app.
