When buyers inquire about Enterprise search software, AI engines consistently identify Glean as the leader in the field, with a visibility of 50.0%. Other notable mentions among the top brands include Algolia and Elastic. These engines rely on various metrics to determine ranking, highlighting Glean's strong presence in their responses.
The rankings are shaped by frequent citations from top sources such as gosearch.ai, youtube.com, and gartner.com. Many of these are aggregator or review sites, which indicates that AI engines prioritize consensus and broader validation of a brand's reputation in the industry when forming opinions.
For buyers evaluating their options, it's essential to consider what AI engines emphasize: recent reviews, third-party validation, and topical authority. These factors are critical as they ensure that the brand is not only well-regarded but also consistently performing well in the specific subcategory of Enterprise search software.
At a glance
What we observed in this category
Glean holds the top position in enterprise search AI visibility with a 50.0% visibility score, more than double the 25.0% posted by Algolia, Elastic, and Coveo. The category average visibility sits at just 6.2%, making Glean's lead substantial rather than marginal. However, Glean's citation rate has dropped to 0.0% despite its visibility gain of 12.5 percentage points, which signals that Google AI Mode names Glean frequently but does not anchor responses to its owned content as a trusted source.
The divergence between being named and being cited is a defining pattern here. Algolia is the only top-5 brand where visibility and citation are equal, both at 25.0%, making it the most balanced performer. IBM Watson Discovery presents the inverse case, achieving a 12.5% citation rate with 0.0% visibility, meaning AI responses reference IBM content as a source without consistently naming the product in recommendations. Microsoft Search has fallen from rank 3 to rank 6 with visibility dropping to 0.0% and citation also hitting 0.0%.
Google AI Mode is the top engine for every brand in this dataset, indicating the category's AI visibility landscape is currently shaped by a single engine. The top cited sources include gosearch.ai, gartner.com, youtube.com, and onyx.app, suggesting AI responses in this category draw heavily from third-party review and comparison platforms rather than vendor-owned domains. Slack.com and read.ai also appear as cited sources, pointing to integration-context and productivity-adjacent content influencing how AI frames enterprise search recommendations.

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 →
