Elmo

Elmo is an open-source AI visibility platform for answer engine optimization (AEO), also known as generative engine optimization (GEO). It shows how AI answer engines such as ChatGPT, Claude, Perplexity, Gemini, Microsoft Copilot, Grok and Google AI Overviews mention, cite and describe your brand. Add the prompts your customers really ask, and Elmo runs them on a schedule across the engines you pick. It measures: - Visibility: how often your brand appears, per prompt and per model, over time - Share of voice against the competitors you track - Sentiment: how each answer describes you - Citations: which pages and domains models cite - Query fan-out: the web searches models run behind the scenes - Opportunities: a ranked list of prompts and sources where you're missing Every metric is computed by readable code with documented methodology. Self-host free with Docker (MIT license) or use the managed cloud from $29/month. White-label for agencies, plus a REST API and MCP server for Claude Code, Cursor and other assistants.
