AI Search
The AI search category reveals a stark divide between established enterprise search infrastructure providers and emerging conversational answer-engines. Traditional players like Elastic, Algolia, and Glean command the highest shortlist rates (52-68%), suggesting buyers prioritize proven search capabilities enhanced with AI over pure conversational interfaces. Microsoft's 43% shortlist rate reflects its dual positioning through Azure Cognitive Search and Bing integration. The category's 22 consensus brands against only 12 evaluation brands indicates mature vendor awareness but selective evaluation criteria, with buyers gravitating toward platforms offering hybrid search, vector databases, and RAG capabilities rather than standalone answer-engines.
