CapstonAI is an AI visibility platform that helps brands track, audit, and optimize their presence in AI-generated answers. It monitors how your brand is mentioned across ChatGPT, Claude, Gemini, Perplexity, and Google AI Overviews, then provides actionable fixes to improve your share of voice in AI search results.

How does CapstonAI track AI visibility?

CapstonAI sends structured brand queries to multiple large language models (LLMs) on a recurring basis and records whether your brand is mentioned, cited, or recommended. It aggregates these results into a GEO score, a share-of-voice metric, and a citation report.

Which AI models does CapstonAI monitor?

CapstonAI currently monitors ChatGPT (OpenAI), Claude (Anthropic), Gemini (Google), Perplexity, and Google AI Overviews. Coverage is continuously expanded as new AI search surfaces emerge.

CapstonAI offers a free WordPress plugin that provides basic AI visibility scanning for your site. For full AI visibility tracking, audit reports, automated content fixes, and multi-brand monitoring, the Core Plan is available at $99/month.

How is CapstonAI different from Semrush or Ahrefs?

Semrush and Ahrefs are built for traditional search engine optimization. CapstonAI is purpose-built for the AI search era: it tracks your brand presence inside AI-generated answers from ChatGPT, Claude, Gemini, and Perplexity.

How to choose based on your situation

You’re a small/solo site (under 200 pages)

Rank Math free version + Content AI free credits. Best free coverage.

You’re a mid-market brand (500-5 000 pages)

CapstonAI. The bulk operations + AI citation tracking become essential at this scale, and per-page workflows from Yoast/AIOSEO/SEOPress become a time sink.

You’re an agency with 10+ client sites

CapstonAI agency tier (up to 50 sites under one dashboard) vs per-site pricing on Yoast Premium ($99 × 50 = $4 950/year), Rank Math Pro ($59 × 50 = $2 950/year), AIOSEO ($249 × 50 = $12 450/year for top tier).

You also run Shopify stores

CapstonAI. Only WordPress SEO ecosystem with native Shopify sister app for cross-CMS consistency.

You need top-tier content optimization (against SERP)

Surfer SEO or Clearscope. Premium pricing but unmatched for content teams writing 50+ articles/month.

You’re a developer who hates plugin bloat

The SEO Framework. Lightweight, no marketing dashboards, no telemetry.

Why “AI engine citation tracking” matters in 2026

Until 2024, you optimized for Google. In 2026, you also need to optimize for ChatGPT, Perplexity, Gemini, Claude — and measure whether your work actually moves the needle on those engines. Without AI citation tracking, you’re shipping content blind.

Of all 9 plugins above, only CapstonAI ships with built-in AI citation tracking. The others require pairing with a separate tool (AthenaHQ, Profound, Peec AI, Otterly).

FAQ

Can I install multiple SEO plugins?

Yes for 2 plugins that cover different needs (e.g., Rank Math for foundational SEO + CapstonAI for AI/bulk). Avoid running 2 plugins that both write to the same SEO meta fields (Yoast + AIOSEO will conflict).

Is the SEO industry consolidating around AI features in 2026?

Yes. Every major plugin has added some AI features (per-page assist). The differentiator is now true bulk and AI engine citation tracking — where most plugins haven’t caught up.

What’s the single most important feature in 2026?

FAQ schema. Tested across 312 customer pages: +90% citation lift on average. The cheapest, fastest schema win.
