Project description: AI agents (ChatGPT, Gemini) are the new search engines, but brands can't track how they're recommended. I built Meridian—an analytics platform for Generative Engine Optimization (GEO). It monitors AI mentions, visibility score, and sentiment across thousands of LLM answers in 10+ languages. The system audits content gaps and generates prioritized fixes to improve Share of Voice in AI responses. Early users saw +9% visibility gains and first-page AI placements. Meridian turns AI discovery from a black box into a measurable, optimizable channel.
