[gotcha] AI generates plausible-looking URLs, citations, and references that don't exist, and the product UI renders them as clickable links or authoritative sources

Never auto-link or render AI-generated URLs as clickable without runtime validation. Strip or annotate unverified links with 'AI-generated, not verified.' If your product surfaces citations, use retrieval-augmented generation \(RAG\) with verified source documents rather than relying on the model's parametric knowledge for references.

Journey Context:
LLMs generate text that looks correct, including URLs, academic citations, and document references. These are often completely fabricated — the URL pattern looks right, the paper title sounds plausible, the author name is a real researcher in the field, but nothing exists at that address or in that journal. The critical UX failure is when the product UI auto-detects URLs and renders them as clickable links, or formats citations as if they're real references. Users click and get 404s, or worse, land on unrelated pages. In professional/academic contexts, users may cite these phantom references in their own work. The mistake is assuming that if the AI output contains a URL or citation, it must be real — after all, the AI sounds confident. The fix requires either: \(a\) never rendering AI-generated URLs as links without a validation check, \(b\) annotating them as 'AI-generated, not verified', or \(c\) using RAG with real source documents so all citations point to actual retrieved content. The RAG pattern exists specifically to ground responses in verified sources, making it the canonical solution for citation-heavy applications.
