When buyers seek recommendations for IT documentation software, AI engines frequently point to IT Glue as the leader in this space, followed by Confluence and Hudu. With IT Glue appearing in 50% of AI-generated answers, its prominence in discussions far exceeds that of its competitors.
The rankings reflect the influence of frequently cited sources like Reddit and YouTube, as well as software review platforms such as Ferndesk. These sites often compile user experiences and expert reviews, providing a comprehensive view of the software landscape and intensifying the visibility of certain brands.
For buyers, this ranking underscores the value assigned by AI engines to platforms that garner recent reviews or third-party validation. Understanding which brands have topical authority in specific subcategories can guide decision-making, helping you choose software that's both well-regarded and backed by community and expert insight.
At a glance
What we observed in this category
IT Glue leads the IT documentation software category with a visibility score of 50.0%, exactly four times the category average of 12.5%. This gap is significant because it means Google AI Mode surfaces IT Glue in response to twice as many queries as its nearest rivals, Confluence and Hudu, both sitting at 37.5%. For brands outside the top three, visibility drops sharply to 25.0% or below, suggesting a steep concentration of AI attention at the top of the ranking.
Citation patterns diverge sharply from visibility in this category. IT Glue holds the top visibility score yet has a citation rate of 0.0%, while ClickHelp sits at rank 8 with zero visibility but a 50.0% citation rate, the highest in the dataset. Confluence is the only top-five brand earning both meaningful visibility (37.5%) and citation (12.5%), making it the sole brand that Google AI Mode both names and links to. This split suggests AI answers describe many brands without anchoring to their owned domains.
Every brand in the top ten lists Google AI Mode as its top engine, confirming the audit is effectively a single-engine landscape with no diversification across other AI platforms. The top cited sources in the category are dominated by third-party and community properties, including reddit.com, youtube.com, and ferndesk.com, rather than vendor domains. ClickHelp and GitBook appear as cited sources themselves, indicating that some vendor content earns reference links even when the brand is not surfaced prominently in AI-generated brand mentions.

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 →
