When buyers inquire about Enterprise search AI, AI engines consistently name Glean as the leader, with a visibility percentage of 37.5%. Close competitors include Elastic and Coveo. This makes Glean the most commonly referenced brand by AI engines, standing out in a field of 20 options.
The rankings are shaped by the domains AI engines frequently cite, with top sources including gosearch.ai and instaclustr.com. Many of these sources are aggregator or review sites, which suggests that AI engines emphasize comprehensive evaluations and broad consensus in their responses.
For buyers assessing this list, it's crucial to consider what AI engines prioritize, such as recent reviews, third-party validations, and authority in specific subcategories. Focusing on brands that have strong presence in these areas may guide you to the option best suited to your needs.
At a glance
What we observed in this category
Glean leads the Enterprise search AI category by a wide margin, with a visibility score of 37.5% against a category average of 3.8%. The next three brands, Elastic, Coveo, and Guru, each sit at 12.5% visibility, meaning Glean is three times more visible than any single competitor. That gap is significant because it suggests Google AI Mode has a strong default preference for Glean when generating answers about this category, giving it disproportionate share of AI-driven exposure.
Visibility and citation do not move together in this category. Elastic, Coveo, and Guru each hold 12.5% visibility but record zero citation, while Algolia and Google Vertex AI Search hold zero visibility yet each achieve 12.5% citation. This means some brands are named in AI answers without being linked as sources, and others are cited as reference material without being surfaced as recommended products. Glean is the only brand that scores meaningfully on both metrics, with 37.5% visibility and 25.0% citation.
The top cited sources in this category are dominated by third-party and niche domains including gosearch.ai, instaclustr.com, nimbleway.com, hebbia.com, and gartner.com, with glean.com the only brand domain in the list. This indicates Google AI Mode is anchoring its answers primarily on external commentary and analysis rather than vendor-owned content. Gartner.com appearing in the source list suggests analyst and review content carries meaningful weight in how this category is structured inside AI-generated responses.

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. More on visibility →
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. More on citation rate →
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. How AI engines pick sources →
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. How AI search ranking works →
