AI Legal Assistant
The AI legal assistant category exhibits clear market segmentation between AI-native startups (Harvey, Spellbook, Luminance) and established legal information incumbents (LexisNexis, Westlaw, Thomson Reuters). Harvey's 70% shortlist rate with maximum model diversity signals strong cross-model recognition as the category leader, while Spellbook and Ironclad cluster tightly at 57-58%, suggesting a competitive second tier. The 46-47% shortlist rates for legacy players indicate their AI offerings achieve meaningful but secondary consideration, likely reflecting brand strength rather than AI-first innovation. However, 0% prompt coverage means no tools were actually tested, leaving a critical gap between perceived market position and validated capability.
