An AI-generated answer may be easy to read but hard to trace. A citation links to a source used to craft the output, giving users a way to inspect its basis rather than relying on the answer alone. section 10.2.2
Source links are a shortcut to a fuller footprint of how an answer was produced, especially when a single-step LLM generation leaves that process opaque. They help users verify an output; they do not reveal every step behind it. section 10.2.2
Figure 10.22 Providing transparency into the original sources is a core strategic differentiator for Perplexity.ai. Other AI systems, especially RAG setups, can also benefit from this UX pattern.
Perplexity.ai illustrates how showing original sources can become a visible part of an AI product’s experience. The same pattern can benefit RAG systems. section 10.2.2
