About this tool

Elmo is an open-source AI visibility platform focused on Answer Engine Optimization (AEO) and Generative Engine Optimization (GEO). It helps brands understand how AI models such as ChatGPT, Claude, and Gemini talk about their brand, which sources they trust, and what specific actions are needed to earn recommendations.

Purpose Elmo's core purpose is to measure and improve a brand's exposure in AI answer engines. Traditional SEO focuses on how web pages rank in search results, whereas AEO/GEO focuses on whether a brand can be mentioned and cited in AI-generated answers. Elmo simultaneously tracks the web searches that AI engines conduct when answering and the sources they cite.

Key Capabilities

  • Coverage of multiple answer engines: Elmo tracks ChatGPT, Google AI Mode, Google AI Overviews, Gemini, Perplexity, Copilot, Claude, as well as models such as Grok, Mistral, DeepSeek, and Qwen. Among these, consumer products such as ChatGPT and Google AI Mode are scraped from the interface users actually see, rather than approximated through APIs; other models are covered through direct API calls and OpenRouter.
  • Visibility and share of voice: It runs fixed prompts to each AI engine on a schedule, scores brands by how often they appear in answers (0 to 100%), and calculates a brand's share of voice relative to competitors based on mentions, while also breaking down the domains and URLs cited by models. Because AI answers vary from run to run, Elmo repeatedly samples and reports trends rather than single-run results.
  • Answer records: Each answer records whether the brand appeared, which competitors appeared alongside it, and which sources the model cited.
  • Opportunity recommendations: It ranks optimization opportunities by impact and continuously updates them so users know what to do next.
  • Self-hosting and data autonomy: Open source, MIT licensed, Docker-based, with all data stored in Postgres, supporting self-hosting at any time, with no lock-in.
  • Integration capabilities: It provides API and MCP access, allowing integration with existing tech stacks and agents.
  • BYOK: Supports Bring Your Own Key (BYOK) to track any AI model.
