The tool allows users to examine mentions, compare visibility, and review cited domains and pages, providing a comprehensive overview of their online presence. Additionally, users can monitor changes in search results over time and utilize an opportunity report to uncover potential strategies for content creation and outreach. The free plan enables users to manage one brand, submit up to 10 prompts, and perform unlimited searches across four primary providers. Meanwhile, the Pro plan enhances functionality by including more AI providers, offering unlimited prompts, and enabling exports in CSV and PDF formats. GEO Checker further provides web tools that assist in evaluating GEO visibility, going through a GEO checklist, and analyzing llms.txt files.

Overall, it serves as a valuable asset for brands aiming to enhance their visibility in the evolving landscape of AI-driven search.
