Fulcru

Fulcru is an AI search visibility tool that tracks whether your brand shows up in AI answers from ChatGPT, Gemini, and Perplexity, and helps you write the pages needed to get cited, aimed at marketers and agencies doing generative engine optimization (GEO). You point Fulcru at your brand and it runs the loop: it finds prompts where you are missing from AI answers, shows which competitors are cited instead, reviews the citation sources behind those answers, generates content briefs, and tracks the lift after you publish. It captures real prompts from actual user interfaces rather than APIs, and reports share of voice, sentiment, and model-by-model comparisons. Fulcru is built for agents and multi-client agency work, with a multi-client dashboard, white-labeling, and API access. It also offers a free set of tools for AI-search readiness: checking whether GPTBot, ClaudeBot, and PerplexityBot can reach your site, and generating an llms.txt file from your sitemap, with no account or card required. Paid brand plans start at $50/month. It is best for SEO teams and agencies who want to measure and improve how often their clients get named in AI search results.
