Our take: Consider Koji if you want an AI moderator to run voice, chat or phone customer interviews in 30+ languages and summarize the findings, after confirming pricing since only EUR figures were found.

Main limitation: Plan prices were published in EUR, not USD, and the pricing page could not be fetched.
