AisleSplit sorts your grocery list by the store you actually buy each item from. Star your go-to store once (Costco for paper towels, Trader Joe's for bananas), and it remembers every week. Snap a receipt and AI pulls out every item and price, building a real price history by store and brand, so you can see where things are cheaper. Works with any grocery store, for just you or your whole household, with one live list shared by up to 3 people.
