Build an "Ask AI about us" widget — a row of icon buttons that deep-link a visitor into their own LLM app (ChatGPT, Claude, Perplexity, Google AI Mode, Grok) with a prompt pre-filled about the product or page. Use this skill whenever the user wants "ask AI" / "open in ChatGPT" / "explain this with AI" buttons, LLM deep links, a way for visitors to learn about the product from their own AI assistant, or wants to add AI-assistant call-to-actions to a site footer, docs, or landing page. Includes the verified per-provider URL schemes and the critical rule that the injected prompt must be self-contained.
