RewardHive is an AI-powered credit card assistant that helps people get the most value out of the cards they already carry—and find the right ones to add. Most people leave rewards on the table. Card benefits are buried in dense terms, bonus categories rotate, and the “best” card changes with every purchase, so people default to one card and quietly lose hundreds of dollars a year in cashback, points, and missed sign-up bonuses. RewardHive solves this with conversational AI agents that do the optimization for you: Which Card? — Describe a purchase (“$200 at Costco”) and it ranks your wallet by rewards, explaining which card to use and why. Wallet Optimizer — Evaluates your current lineup and tells you whether a new card would actually improve your returns. Recommendations — Searches a catalog of real credit cards to suggest the best match for your spending profile. Conversational profiling — It learns your spending habits as you chat, so advice sharpens over time.
