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.

You need image optimization + alt text generation + meta descriptions

CapstonAI. Combines all three plus AI citation tracking under one workflow.

You’re on Cloudflare already

Just enable Cloudflare Polish. No additional plugin needed.

You want zero subscriptions

WebP Express (free) for WebP only, or EWWW with local optimization (free for basic use).

You also run Shopify stores

CapstonAI. Sister app handles Shopify image optimization (ShortPixel and others are WP only).

FAQ

How much do these tools actually save in page weight?

Average across customer audits: WebP cuts image weight 26% vs JPEG/PNG. Combined with smart per-image quality, total page weight drops 34-42% on image-heavy sites (CapstonAI Q1 2026 benchmark across 18 customer sites).

WebP vs AVIF: which to choose?

Both. AVIF compresses better (additional 10-15% over WebP) but has 94.6% browser support vs 97.4% for WebP. Serve AVIF first via element, fall back to WebP, then JPEG/PNG. Most modern tools handle this automatically.

Can I keep ShortPixel and add CapstonAI?

Yes. If you only want CapstonAI for the alt text + meta + AI tracking layer, keep ShortPixel for compression. They coexist. CapstonAI honors existing WebP files and won’t re-process.

Why does AI citation tracking matter for image optimization?

Because slow pages get throttled or skipped by AI crawlers (GPTBot, ChatGPT-User, PerplexityBot). Pages reduced from 3+ MB to under 1.5 MB get 23% more crawl coverage and 18% more Perplexity citations on average (CapstonAI customer data, Q1 2026).
