GEO Checker

GEO Checker is an AI search visibility and Generative Engine Optimization tool for teams that need to understand how their brand appears in AI answers, not just where a page ranks in classic search. The website gives a free GEO readiness check for any URL, and the browser extension is built for real AI visibility measurement. In the extension, you can set up your product name, website, aliases, competitors, and the prompts you want to track. Then you can run those prompts across AI engines from your own browser sessions and capture what each engine actually answers. GEO Checker tracks product mentions, competitor mentions, citation links, cited domains, visibility percentage, per-run summaries, citation sources, and visibility trends over time. It helps founders, SEO teams, content teams, and marketers find where their brand is missing, which competitors appear more often, which sources AI engines cite, and which prompts need better content support. The extension is local-first. It does not require a GEO Checker account, backend, or API key. Your prompts, results, and AI sessions stay in the browser. This makes it a practical way to test AI search visibility, compare prompts, discover citation gaps, improve GEO content, and build a clearer path from SEO work to AI citations. It is useful for tracking visibility across ChatGPT, Claude, Gemini, Grok, DeepSeek, Kimi, Doubao, Perplexity, and Google AI mode, while keeping the workflow simple for small teams.
