Verdict
Choose Scrunch when
- AI-search / GEO matters to you. Core product is explicitly AI-search visibility, citations, brand presence, model comparison and AI-answer optimization.
- Research depth matters to you. Strong AI-search research and monitoring depth across prompts, models, competitors, citations, sentiment and trends.
- Context gathering matters to you. Uses site maps, AI-bot traffic, citations, competitors, personas, funnel stages and internal sources/Knowledge Studio in the official product announcement.
- GEO readiness matters to you. Site Diagnostics identifies blockers and citeability/retrievability opportunities; AXP can serve agent-ready HTML, but AXP is an Enterprise/custom capability.
