Llumo

Llumo is a free AI visibility tracking platform that lets you monitor how large language models like ChatGPT, Gemini, Perplexity, and Claude talk about your brand. It scrapes AI responses and shows you exactly when your brand is mentioned, cited, or missing entirely. You get a dedicated instance on your own subdomain, with no monthly software fee — you only pay the underlying AI provider costs if you bring your own API keys.

The platform tracks visibility scores per prompt, share of voice against competitors, and the actual searches AI engines run when answering your queries (query fan-out). Citation analysis shows which domains are cited most and where your brand is absent. You can organize prompts with tags, search across all data, and see trends over time. Llumo supports ChatGPT, Claude, Gemini, Grok, Mistral, DeepSeek, Perplexity, Copilot, Google AI Mode, and AI Overviews. A free tier gives 200 prompts per day, translating to roughly 42,000 AI responses at a fraction of the cost of traditional AI visibility tools.

Llumo is built for SEO professionals, marketing teams, and brand managers who need to understand their brand's presence in AI-generated search results. Use it to track how your brand appears in AI answers, find opportunities to earn citations, and stay ahead of competitors. It's particularly useful for anyone managing brand reputation in the AI search landscape, from startups to enterprise marketing departments.
