What we observed in this categoryauto-generated
Glean dominates the enterprise search software AI visibility landscape with a 37.5% visibility score, exactly 9.9× the category average of 3.8%. Coveo sits second at 25.0%, creating a clear two-brand tier before Microsoft Search at 12.5%. Below those three, every other tracked brand — including established players like Elastic, Algolia, IBM Watson Discovery, and Sinequa — registers 0.0% visibility, meaning the top three brands absorb all meaningful AI narrative share across this 20-brand category.
Luigi's Box presents the most notable divergence between visibility and citation: it holds 0.0% visibility yet earns a 12.5% citation rate, producing a composite score of just 3.8. This means Google AI Mode references Luigi's Box as a source or data point without describing it as a featured solution — a 'cited but not named' pattern. By contrast, Glean, Coveo, and Microsoft Search show identical visibility and citation percentages, indicating full narrative alignment where being mentioned and being cited coincide precisely.
All recorded AI visibility and citations in this category originate exclusively from Google AI Mode; no other engine contributes to any brand's score in the audit data. The top cited external sources include gosearch.ai, meilisearch.com, gartner.com, alpha-sense.com, reddit.com, and youtube.com — a mix of niche AI search tools, analyst coverage, community forums, and video content. The presence of gosearch.ai and thunai.ai among top cited sources suggests Google AI Mode is anchoring category comparisons partly on smaller, AI-native search entrants rather than solely on legacy enterprise vendors.

Sources AI engines trust in this category
Across the 8 buyer-intent queries we ran on enterprise search software, these are the domains Google AI Mode cited most often. If you're not on this list — or if your competitors are — that's a concrete PR / linkbuilding target.
How to read this ranking
Four things worth knowing before you act on the numbers above. These are the same definitions across every industry page — for category-specific observations, see the What we observed section above (where available) and the per-brand insights inline in the ranking.
Visibility = being named
A brand's visibility % is the share of AI answers that mention it by name in the response prose. This is who AI engines actively recommend to the buyer.
Citation rate = being trusted
Citation rate is the share of AI answers that include the brand's domain as a clickable source link. This is what the AI treats as authoritative evidence — different from being named.
Top engine differs by brand
The "top engine" column shows which AI surface each brand performs best on. Big gaps between a brand's score across engines usually points to specific content or schema gaps.
Rankings move month to month
AI engines re-crawl and re-rank on shorter cycles than classical search. We re-audit every brand on this list at least every 30 days and refresh this page automatically.
