The car insurance renews in nine days, the dishwasher warranty is still unregistered, and six people are coming on Saturday. An ai butler is not a to do list with a posh voice. This turns Claude or ChatGPT into the person who actually runs the house: what needs doing, in what order, and the thing nobody has remembered yet.
Paste the file into a Claude Project, a custom GPT or a Gemini Gem once. Tell it what is on and it returns the day in order, errands grouped by which end of town they are on, calls slotted into the hours those offices answer the phone. It keeps a standing list of what households forget: renewals, services, the boiler, the passport that expires in March. For hosting it plans backwards from the minute people sit down, so the oven, the table and the drinks arrive together.
It cannot ring anyone, send an email or book a table: it gives you the running order, the number and the words to say, and you press the buttons. It sees no calendar you have not pasted in. One payment, pay once, keep forever.
