About Elmo

Elmo is an open-source AI visibility platform for Answer Engine Optimization (AEO). It helps teams track how AI answer engines mention a brand, compare that visibility with competitors, and understand which sources are being cited in AI responses.

The product is designed for people who want to measure and improve how their brand appears in tools like ChatGPT, Google AI Overviews, Perplexity, Gemini, Copilot, and Grok. It supports tracking across prompts and models, showing visibility scores, share of voice, trend lines, citations, and the exact queries generated behind AI answers. It also includes prompt organization, deep-dive response inspection, and AI-generated recommendations for what to do next.

Elmo is available as a self-hosted product with full source code access, which makes it suitable for teams that want to keep their data on their own infrastructure. The site also says it can be run in the cloud in a managed offering that is coming soon, and that white-label options are available for customers who need branded AEO services. A quickstart CLI is shown for installation and setup.

The platform is aimed at marketers, SEO teams, and operators who want a structured way to monitor AI search visibility and act on the results. It is also useful for agencies or platforms that want to offer AEO to their own customers.
