It is a little more than semantic search. Their value prop is curation of trusted medical sources and network effects--selling directly to doctors.
I believe frontier labs have no option but to go into verticals (because models are getting commoditized and capability overhang is real and hard to overcome at scale), however, they can only go into so many verticals.

Interesting. Why wouldn't an LLM based search provide the same thing? Just ask it to "use only trusted sources".
