Most store terms are lifted from another shop's page, which is how a returns window from another country and a clause about software licences end up on a site selling candles. This terms and conditions generator prompt starts from your shop instead: what you sell, who you sell it to, where you ship, when an order actually becomes a contract, and what your returns policy really is.
Paste it into Claude, ChatGPT or Gemini and it asks eight questions, then writes ordering and acceptance, pricing and listing errors, delivery and the point risk passes to the buyer, returns and refunds, consumer cancellation rights, age limits, account misuse and liability. It is written for a shop that takes orders and ships goods, not for an app or a subscription product. It hands the result over as a draft and tells you to put it in front of a lawyer before it goes live if you take payment in a regulated market.
Buy it once and reuse it. Redraft your terms when you add a product line, open a second country or change the returns window, and keep the version you replaced.
