A smart comparison tool that analyzes users' actual spending habits (via bank transaction imports or manual category input) and recommends the optimal card or combination of cards to maximize cashback and rewards. The tool continuously monitors changing card offers, sign-up bonuses, and category multipliers across providers, alerting users when a better option becomes available or when they should shift spending to a different card for higher returns.

The explosion of fintech cards (Revolut, Hype, Bybit, Satispay) and crypto-linked cashback options has made the rewards landscape far more complex than traditional bank offerings, while consumers are increasingly cost-conscious and seeking to optimize every purchase amid inflation pressures.
