AI Search
AI search is a two-brand race for discovery attention. Elastic surfaces in 83% of buyer queries about enterprise search and AI-powered search tools, visible across ChatGPT, Claude, Gemini, and Perplexity. Algolia lands in 63% of the same queries with identical four-engine visibility, while Glean trails at 49%. The category is contested — no single brand owns the conversation, but Elastic and Algolia together account for most AI citations in discovery prompts. When buyers pit tools head-to-head, the picture shifts: Elastic wins more comparison queries than it loses, Glean holds its ground, but Algolia scores near the floor despite strong discovery share.

The shortlist
Across 35 buyer-style "AI Search" queries
Elastic shows up in more than four out of every five buyer queries about AI search and enterprise search tools, visible across ChatGPT, Claude, Gemini, and Perplexity. Algolia surfaces in 63% of those same queries with the same four-engine footprint. Glean lands in 49% of discovery prompts, also across all four engines. No other brand breaks 35% — Lucidworks Fusion, Microsoft Copilot, Constructor.io, Bloomreach, Weaviate, and Perplexity each hover between 26% and 34%, fragmenting the rest of the shortlist.

Buyer questions
What AI cites for top AI Search questions
Buyers ask AI for enterprise search tools by deployment model and use case — phrasings like 'best AI-powered enterprise search tools for internal company knowledge', 'which RAG-based search tools query private knowledge bases with LLMs', 'top search platforms with merchandising controls and result boosting for content teams'. The questions stay top-of-funnel, naming workflows and technical requirements. No head-to-head comparisons, no pricing questions, no trust or conversion prompts surface in the current query set.
