The official feature claims describe AI writing and algorithms, not agents, tool calling, or an agent runtime: https://www.growthbarseo.com/
Rank Math
AI assistants and one-click AI fixes exist, but the product is primarily a WordPress plugin and official sources do not document an autonomous agent API or agent orchestration.
