Cut your grocery bill with a chatbot's shopping plan
Added October 21, 2026
Tell a chatbot what you spend on groceries each month and ask for ways to spend less without eating less, then try the few tips that fit how you shop.
What happened
On October 21, 2026, a Tom's Guide writer said a $400 grocery run made him ask ChatGPT and Gemini for ways to spend less without eating less. He kept five tips: buy store brands for staples, compare unit prices instead of package prices, swap some meat meals for cheaper proteins like beans, lentils and eggs, buy frozen produce out of season, and do your own prep instead of paying for pre-cut or pre-shredded food. He reported that his next grocery bill was $300.56. The chatbots' monthly savings estimates were their own guesses, and this is one writer's account of one shopping trip, not a controlled test.
Our verdict
Worth a try. The tips are basic, but a chatbot can tailor them to your own list and estimate which changes matter most. The savings come from changing how you shop, not from the chatbot itself.
Tools
Any general chatbot (ChatGPT, Gemini, Claude, Copilot); your store's app or shelf tags for unit prices
