The chat bubble on your site is either useful or a liability, and the difference is the prompt behind it. This is a ready-made system prompt, not a widget: text that tells an AI model how to answer visitors using only your plans, your prices, your policies and the page list you give it.
Inside you get a 15 point questionnaire, the full system prompt built for a website widget (answer first, up to four lines of structure, exactly one link and only to pages you listed, page context awareness, lead qualification, and a hard rule against confirming features you did not list), setup steps for Claude, ChatGPT, Gemini and your widget or n8n and Zapier, five pre-launch tests, and five sample conversations.
One payment, pay once, keep forever, no software. Paste it into any chat widget or AI tool that has a system prompt field, and update the questionnaire whenever your pricing page changes.
