Which AI Video Generator Do AI Engines Recommend Most? (2026 Cross-Engine Leaderboard + Citation Autopsy)

A cross-engine measurement of which AI video generation tools five grounded AI answer engines (ChatGPT, Gemini, Google AI Overviews, Grok, Perplexity) recommend, plus a citation autopsy of the 284 sources those engines cited. Measured 2026-06-17. 22 tools ranked by cross-engine consensus (engines-naming) and mention volume; Creatify is the only tool named by all five engines. Citation autopsy finding: 33 percent of citations point to the vendors own sites, a markedly higher vendor-cited share than the B2B/GTM companion study. Asymmetric query coverage disclosed (only 4 of 16 prompts answered by all five engines) so no cross-engine agreement coefficient is computed. Part of the Lattice AI-recommendation research family.
