Deltek: AI Visibility Report
When buyers ask ChatGPT, Claude, and Gemini about architecture & engineering (aec), Deltek ranks #12 of 15, a Visibility Score of 6 in Architecture & Engineering (AEC) .
These rankings are measured from what the three models know from training, not a live web search. The live-web grounded surface is rolling out across the index. Methodology.
Deltek barely registers in the one AEC race it runs.
Where it wins. It does appear in general 'Top tools in 2026' AEC conversations, and its 6.9% mention rate keeps it from total invisibility in a 15-competitor field.
Where it loses. Ranked 12th with a score of 6.4, Deltek loses ground to BQE CORE, Monograph, and BST Global on nearly every practical buying prompt, and the AI models skip it entirely when buyers ask about use-case fit, team size, or a single best pick.
