Verdict
Choose Kafkai when
- Keyword research quality for SEO content matters to you. Provides keyword gaps, strategy tagging, and topic analysis, but not a large general keyword database.
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.
- 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.
- Technical SEO matters to you. Diagnoses AI-bot access, JavaScript, load and structure issues, but does not document a broad traditional technical-SEO crawler.
- Free tools matters to you. The site offers a free AI visibility audit with results in 30 seconds and no credit card; this is not evidence of a permanently free product tier.
