If you're drowning in keyword lists and need to figure out what content to actually build, this organizes everything into topic clusters with pillar pages and internal linking structures. You give it keywords, it groups them by intent and semantic similarity, then outputs a content hub architecture with specific article titles, word counts, and a phased roadmap. The templates are pretty thorough, maybe overly so if you just need quick clusters, but they cover the full SEO content strategy workflow from research to implementation checklist. Good for when you're planning a content hub and want the whole strategic framework, not just grouped keywords.
