This is a ready to use system prompt for an online store chatbot, not a piece of software. You fill in one questionnaire about your policies and catalogue, paste the prompt into any chat tool that accepts a system prompt, and it handles the four questions that fill an ecommerce inbox: where is my order, can I return this, what size am I, and is it in stock.
Inside the file you get the store questionnaire, the full system prompt, install instructions for a Claude Project, a ChatGPT custom GPT, a Gemini Gem and an n8n, Zapier or Make automation, five test messages with the correct answers, and five sample conversations. The bot is built to never invent a delivery date or a stock level: it collects the order number and email and routes the shopper to tracking or to a human.
One purchase, yours forever. Pay once, keep forever, no account, nothing to install. It runs in Claude, ChatGPT, Gemini, Copilot and any platform with a system prompt field, and you edit it yourself whenever a policy changes.
