GEO Checker

GEO Checker is an AI visibility tracking tool used to track brand mentions, citation sources, and competitor performance on platforms such as ChatGPT, Gemini, and Google AI. Users can add brands, competitors, and real customer questions, send the same prompt to multiple AI engines within their own logged-in browser session, and then compare brand appearance frequency, competitor mentions, and the sources cited by AI, thereby discovering visibility gaps and formulating action plans. It emphasizes capturing real AI answers rather than simulated estimates.

About this tool

GEO Checker is a tracking tool for AI search visibility (GEO, generative engine optimization), helping brands understand how they appear in AI answers and compare with competitors.

Purpose

GEO Checker is used to measure a brand's GEO and AI search visibility. Centered on real customer questions, it tracks brand mentions in AI answers, ChatGPT citations, Perplexity results, cited sources, and competitors' share of voice, helping users discover gaps and turn AI visibility into new customers.

Main capabilities

  • Run prompts across multiple AI engines at the same time: send one question to ChatGPT, Gemini, Grok, Google, and other AI engines for side-by-side comparison, all completed in the user's own browser. The official description says no API key is needed, and no copy-pasting is needed.
  • Measure share of voice in AI answers: see how often AI engines mention the brand and competitors together in answers, presented in a leaderboard format.
  • Track AI visibility trends: measure each prompt across providers and observe visibility trends after each run.
  • See the sources cited by AI: identify the domains and pages behind AI answers, helping users determine where to seek their next mention.
  • Customize what to track: set products, prompts, competitors, and AI engines. Core monitoring history is stored in the browser; optional online features send only the necessary input.
  • Turn monitoring data into action: GEO Checker reviews the past 30 days of prompts, brand mentions, and competitor citations, categorizes next-step suggestions into four types: new content, page updates, outreach, and community work, and prioritizes the highest-impact actions. Users can also see the citation sources behind each suggestion.
  • Competitor analysis: add competitor names, domains, and aliases, and GEO Checker will detect whether they appear in every captured AI answer and citation, so users can compare share of voice under the same set of prompts, see which competitor pages and domains are cited, and track whether the visibility gap is widening or narrowing.

How to use

According to the official introduction, there are three steps:

  1. Add the brand and customer questions: enter the website, add the competitors you care about, and save the questions buyers really ask before choosing.
  2. Run the same prompts in AI tools: send each question from the user's logged-in browser session to ChatGPT, Gemini, Grok, and Google.
  3. View the produWhere and why the brand appears: compare visibility, competitor mentions, and cited sources, then decide what content to create or improve next based on the gaps.

GEO Checker is available as a browser extension, and the official instructions say it can be added from the Chrome Web Store and requires a logged-in browser session to capture AI answers.

Use cases

Suitable for teams or individuals who want to understand a brand's exposure in AI answers, for example tracking brand mentions and citations, comparing share of voice with competitors under the same set of questions, discovering the source pages cited by AI, and planning content creation, page optimization, outreach, and community work accordingly.

Limitations and characteristics

  • The official description emphasizes that its results are "real AI answers" rather than estimates: most AI visibility tools simulate or estimate what AI engines might say, while GEO Checker captures what they actually say. Officially, it is compared with "simulated or estimated visibility," which uses simulated queries or API calls, provides estimates or predictions based on algorithmic models, and cannot guarantee the accuracy of real-world AI rankings.
  • Data privacy: core monitoring history is stored in the browser; optional online features send only the required input. The official FAQ includes an item on "Is my data private," but the materials do not provide specific details of the privacy terms.
  • Whether it changes the website: the official FAQ lists the question "Does it change my website," but the materials do not provide the answer.
  • How the AI visibility score is calculated: the official FAQ lists this question, but the materials do not provide the specific calculation method.
  • Reasons results change: the official FAQ lists "Why do my results change," but the materials do not provide a specific explanation.
  • Supported AI engines: the official FAQ lists "Which AI engines does it support," and the main text mentions ChatGPT, Gemini, Grok, Google, and Perplexity, but does not provide a complete support list.
  • Fees and pricing: the official FAQ lists "How much does it cost," but the materials do not provide a specific price or charging model.
  • Installation time: the official FAQ lists "When can it be installed," but the materials do not provide a specific time.
  • Difference from cloud-based AI visibility trackers: the official FAQ lists this question, but the materials do not provide a specific comparison explanation.
