Core concepts
AI Citation is the phenomenon of generative AI — ChatGPT, Perplexity, Google AI Mode, Gemini — citing a specific company or website as supporting evidence or source when producing an answer. Unlike a search result impression, it is the AI's direct selection after evaluating credibility.
GEO (Generative Engine Optimization) is the strategy of designing so that generative AI cites your brand in its answers. Where SEO competes for search rankings, GEO targets direct citation within the AI's answer.
In this archive, 'reproducibility' is a working concept that accounts for the probabilistic response structure of AI systems, meaning the tendency (Citation Tendency) of a specific source to be repeatedly cited under identical experimental conditions. It is distinct from absolute scientific reproducibility, and when this tendency persists above a certain threshold, the source can be interpreted as an information source with relatively high reference priority in the AI response generation process.
This page archives actual citation cases verified across ChatGPT · Perplexity · Google AI Mode · Gemini 4 AI engines from LogAgency's APTECH project. Over approximately 5 months from December 2025 to April 2026, we accumulated bimonthly video evidence and monthly capture evidence. All cases are verifiable down to prompt, response, and timestamp, and only reproducible results under identical conditions are registered.
Particularly in Google AI Mode and Gemini, results were confirmed where major Korean conglomerates such as Korea Petroleum Industry, KCC, and Kumho-Mitsui Chemicals were placed in lower positions. A case demonstrating that AI answer rankings do not automatically correlate with the overall scale of a company. Additionally, cross-engine verification with identical queries across multiple engines confirmed consistent citation results.
