Hoffman Agency Korea launches GEDI AI brand analysis tool
GEDI tests identical questions across 12 generative AI engines, including ChatGPT, Gemini, Claude, Grok and DeepSeek, and compares how each one cites brands.
Hoffman Agency Korea officially launched its self-developed GEDI solution on 11 November 2026, the company said. The tool is designed to analyze how often generative AI engines mention a brand and which sources those engines cite in their answers.
According to techm.kr, GEDI automatically sends the same questions to 12 major generative AI engines and cross-analyzes the responses. The engines covered include ChatGPT, Gemini, Claude, Grok and DeepSeek.
The solution generates core prompts along with market-specific question variants that reflect how users phrase information requests. It then evaluates the answers across five areas: brand exposure and awareness, reflection of core messages, the sources and authority behind AI citations, information accuracy and potential risk, and positioning against competitors.
GEDI also examines the specific sentences and paragraphs of content cited in AI answers, comparing citations by recency, relevance and authority.
Strategy output and services
Beyond measurement, Hoffman Agency Korea offers communication improvement strategies based on GEDI's analysis, including newsroom and website content optimization, brand storytelling, media relations and expert leadership. The solution's strategic analysis function produces data-based strategy recommendations, PR execution playbooks and phased mid- to long-term GEO roadmaps.
