AEO tools fall into three buckets: schema generators, llms.txt managers, and end-to-end platforms that do both plus citation tracking. The end-to-end platforms win because AEO is a system, not a checkbox.
If you want one tool, pick an end-to-end AEO platform that attaches to your live site with one script tag, configures schema and llms.txt, and tells you where you are cited.
SiteSonar is the end-to-end AEO platform: AI visibility, curated answers, visitor identification, and conversion routing, all from one script tag. See the full platform →
Standalone schema generators (Schema App), llms.txt editors, and citation trackers (Profound, Otterly) each cover part of the job. They work, they just leave you to stitch the parts together.
