There's a coffee shop downtown that has a chatbot on its website. Ask it anything: "What oat milk options do you have?" "Are you open on holidays?" "I'm allergic to nuts, what can I safely order?" "What's the WiFi password?" It answers every question instantly, accurately, and with the same friendly personality as the baristas.

The shop owner built it in an afternoon. She wrote a detailed system prompt describing the menu, hours, policies, and the shop's personality. She fed in the allergen information for every item. Now the chatbot handles 50+ customer questions per day that used to interrupt her staff.

You don't need to be a tech company to build a chatbot. You need a clear purpose, good information, and the right system prompt. Today you'll build one from scratch.
