The short version: Stackwise is a shopping optimisation layer that helps you combine the rewards and savings already available to you.
One decision surface for discounts, gift cards, cashback, loyalty and card rewards.
It compares relevant discounts, cashback, gift cards, loyalty benefits and card rewards, then suggests an order of actions for a purchase.
The current product is designed as a recommendation layer. It does not need to hold your money or know your CVV or PIN to tell you which route appears best.
The roadmap is to support major browsers. A Chromium-based extension is the natural starting point, followed by other browsers as usage grows.
Yes. Cashback portals are a core part of the comparison because they can materially change the best route.
That is part of the planned setup experience: identify the card product from a photo without storing sensitive payment credentials.
That is a future expansion path. With user permission, a mobile experience could use location/context to suggest the best payment or loyalty route in person.
The long-term model can combine a premium subscription, disclosed affiliate/referral revenue and B2B partnerships. The ranking experience should remain transparent.
No. It is a shopping and rewards comparison tool. Users remain responsible for checking current product terms and deciding how to pay.
