Both are ai visibility monitoringtools, and both have been checked field by field against their own sites. Below is where they actually differ — and where we couldn't establish a difference.
Profound. A full-stack AEO platform that runs daily structured prompts against up to nine AI answer engines from the real consumer-facing experience (not vendor APIs), pairs that with server-log-based AI crawler/traffic analytics, and closes the loop with agent-built, CMS-published AEO content.
Semrush. Tracks mentions and citations of your brand across ChatGPT, Perplexity, Gemini, Claude, and AI Overviews.

Not published is not a no.Where a vendor never states whether it does something, we say so rather than printing a verdict we can't source — so an empty-looking row is a gap in their documentation, not a missing feature.
