AI Visibility Tracking

Elmo vs Xofu

Elmo is an open-source, self-hostable alternative to Xofu, an AI visibility tracking tool. Both measure how AI answer engines describe your brand, but Elmo ships every line of code, runs on your own infrastructure, and is free to self-host — so your data stays yours and each metric is independently verifiable.

About Xofu

Xofu deliberately narrows to the prompts buyers use when shortlisting vendors — best X for Y, vendor comparisons, solution evaluations — across ChatGPT, Google AI Overviews, AI Mode, and Gemini, tracking recommendations over time. Citation gap analysis shows which sources get cited when competitors appear and the brand does not, prioritizing pages to improve and publishers to target. It ships a snapshot report and an entity audit, free to start with no card.

Popularity grade: B

  • Scoped to bottom-of-funnel shortlisting prompts rather than all mentions
  • Citation gaps returned as a publisher target list
  • Standalone entity audit alongside the tracker
