Citations
Every claim carries a pointer back to where it came from.
Named by Shape of AI. The pattern that separates “search that answers” from “chatbot that asserts.” The interesting design space is where the citation lives: inline superscripts (Perplexity), per-passage jumps (NotebookLM), or source chips (Quark) — each trades reading flow against verifiability differently.
Why it works. Users rarely click sources — but their presence changes trust, and the 5% of clicks that happen are the highest-stakes moments in the product.
Steal: make the jump land on the exact passage, not the page top. Skip: citation theater — decorating ungrounded generation with links it didn’t actually use.
