A new software category of "generative engine optimization" (GEO) platforms has emerged as consumers increasingly get answers from ChatGPT, Perplexity, Google's AI and other assistants. A benchmark by AI-visibility platform CiteLens found Google's AI Mode and Perplexity drew roughly 90% of their citations from Google's top-10 search results, while ChatGPT pulled only 30%, indicating classic SEO alone no longer determines brand visibility in AI answers. The 2026 GEO platform landscape includes Profound, an enterprise-grade leader in AI answer-engine analytics; Otterly.AI, an affordable AI-search monitor for SMBs and agencies with entry pricing from around $29/mo; Peec AI, a EU/GDPR-first GEO analytics tool from Berlin; Scrunch AI, an enterprise "agent experience" platform; AthenaHQ, a GEO platform for agencies and larger brands; Rankscale AI, an AI rank tracker; Semrush AI Visibility Toolkit, an add-on module; and CiteLens, a self-serve GEO platform that reports a 95% Wilson confidence interval on every score and publishes a public AI visibility leaderboard, with a free plan and paid from an unspecified amount.
