Elmo is an open-source platform designed for tracking and optimizing brand visibility across AI answer engines. It addresses the needs of organizations and marketers seeking to understand how AI models mention, cite, and represent their brands in generated responses. The tool specifically supports Answer Engine Optimization (AEO), which focuses on measuring and improving a brand's presence in AI-generated answers, as opposed to traditional search engine rankings.
The platform enables users to monitor brand mentions, analyze citations, and benchmark their visibility against competitors across a wide range of AI models, including ChatGPT, Google AI Overviews, Perplexity, Gemini, Copilot, Grok, and others. Elmo provides a dashboard that displays current visibility, trends, citation breakdowns, and key metrics. Users can filter visibility data by AI model, time range, and tags, and view per-prompt visibility scores with comparative trend lines. The tool allows for detailed citation analysis, identifying which domains and URLs are most frequently cited by AI models, tracking changes in sources over time, and categorizing citations by brand, competitor, social, and more.
Additional features include the ability to search, tag, and organize prompts, as well as inspect individual AI responses to see which brands are mentioned, what sources are cited, and how responses are constructed. Elmo also offers competitive benchmarking, enabling users to compare their brand's AI mention rate against competitors and identify areas where their visibility can be improved. Trend tracking over time helps users observe the impact of content changes and market shifts on their AI visibility.
Elmo is delivered as a self-hosted solution, allowing organizations to run the platform on their own infrastructure with full access to the source code, ensuring data privacy and avoiding vendor lock-in. It is free and open source to self-host, with no license fees or per-seat pricing, and users only incur costs for their own infrastructure and any AI provider API keys they choose to use. Managed cloud hosting and white-label options are also available for those seeking additional support, branding, or integration features. The platform is developed by Blue Whale Software, LLC.
