Definition

Claude is Anthropic's AI engine, launched March 2023. It is positioned as the AI engine for professional and enterprise use — particularly favored among writers, researchers, knowledge workers, and developers for its longer context handling and editorial discipline.

Why it matters

Claude's user base over-indexes on decision-makers — journalists, analysts, executives, and professional researchers. The brands that surface in Claude's answers reach the audience that writes about, analyzes, and recommends categories to others. Citation Share on Claude carries downstream amplification weight that consumer-volume metrics underweight.

Example

An asset management firm's audit shows similar Citation Share across consumer engines but a 14-point gap on Claude. Subsequent investigation shows the gap is being filled by financial trade press coverage the firm had deprioritized. The Claude audit reorganized the trade press strategy.
