Sill

Sill is the intelligence platform for AI brand visibility. Your buyers ask AI before they ask Google — and AI only cites 2–4 brands per response. Sill tracks whether yours is one of them, detects what's going wrong, tells you what to fix, and proves whether your changes worked.

Four integrated modules:

Pulse — Daily visibility monitoring across ChatGPT, Gemini, Perplexity, Claude, Grok, and Google AI Overviews. Tracks Share of Voice, mention rate, citation share, content score, and sentiment. Queries classified into Defend/Grow/Aspire tiers. Competitive benchmarking against up to 6 brands.

Vanguard — Citation and sentiment intelligence. Identifies which sources AI trusts, how sentiment differs by platform, and where competitors get cited and you don't. Watchdog detects hallucinations — fabricated features, wrong pricing, outdated info — before customers see them. Query fan-out analysis reveals hidden sub-queries AI runs behind the scenes.

Compass — Prioritized content recommendations ranked by predicted impact. Each includes target URL, affected queries, effort estimate, and step-by-step instructions. Integrates with WordPress, Shopify, Webflow, HubSpot, Ghost, and more.

Lab — Controlled experiments that establish causality. CMS webhooks detect changes automatically. Measures SOV shift per platform, per query, with statistical confidence. No A/B test setup, no minimum traffic. The only rigorous way to prove GEO changes worked.

Also includes GA4 traffic attribution, PDF reports, multi-brand support for agencies, and AI topic mapping.

Built for SEO/AEO teams, content teams, leadership proving ROI, and agencies scaling across clients. Free tier with 2-week trial. Paid from $90/mo.
