CMO Owls is a parliament of 21 specialized AI marketing agents that work from one shared strategy: SEO and GEO audits, content drafting and scheduling, social intelligence and competitor tracking, connected to a business's real website and accounts.
Here we publish the free tools behind cmoowls.com/tools as open source (MIT): plain code, no AI calls, nothing stored.
