Real use cases (2)
Real use caseMoney & bills
Swap a budgeting app for a spreadsheet and an agent
The poster dropped his finance tracking app. He keeps a Google Sheet and uses a Gemini Spark skill: he tells it what he spent, it logs it, and it answers questions about his spending. He says the same idea works for workouts or anything else you track.
Real use caseMoney & bills
Get money back when the price drops right after you buy
Two weeks after buying a Pixel phone, the poster saw a $250 promo on the same model. He had Muse contact Google Store support about it, and says he got $270 back without doing much himself. He doesn't share the steps, so treat it as one person's result.
