What is 'Grove' and is anyone trying to replicate its interactive voice questionnaire feature?

One member mentioned a tool called Grove that has a voice-based interactive client questionnaire feature. Another member said they haven't used Grove directly but, after discovering the concept, are working to replicate it themselves — they are close to having a fully interactive, verbal client questionnaire built, though they haven't spent much time on it yet. A third member expressed interest in looking into Grove based on this description.
