FanoutFox: AI Answer & GEO Inspector, developed by Suganthan Mohanadasan, is a Chrome extension that exposes how generative engines research user prompts. It lets analysts inspect the research steps ChatGPT performs before producing an answer. The tool highlights hidden sub-queries, tracks citations and mentions, and performs analysis from the active browser session. It targets SEO specialists, digital marketers, brand managers, and web developers who need actionable insight into AI visibility.

How it embeds into Chrome and the ChatGPT interface

The extension installs as a Chrome add-on and integrates directly into the ChatGPT interface, so analysis appears alongside generated answers rather than in a separate app. It is available for Google Chrome and other Chromium-based browsers such as Microsoft Edge and Brave. This placement means users can inspect AI behavior in-context while crafting prompts or reviewing responses without switching workflows.

How large the extension is and what it adds to a browser

The installer is approximately 430 KiB, a small binary compared with typical browser extensions. That compact size keeps disk and install footprint low, and the extension is designed to load inside the browser session rather than run as a remote service. Because it is a browser add-on, deployment and updates follow standard Chrome extension management workflows.

How it treats data and supports GEO auditing

The extension uses a privacy-first architecture, operating without a central server or account requirement and performing analysis locally on the user’s machine. Its auditing module inspects pages for AI-friendliness, checking crawlability and the presence of clear, citable data, then produces a score plus actionable fix tips. Optional, toggleable integrations include Ahrefs for domain ratings and Reddit for thread engagement statistics, which appear as add-on data points in the audit output.

A focused specialist tool for analysts and SEO practitioners

Built by Suganthan Mohanadasan, FanoutFox is aimed squarely at practitioners who measure AI visibility, not casual browsing. The extension’s 5.0-star Chrome Web Store rating reflects strong early interest among SEO users. Practical advice: compare the extension’s audit findings with your crawl logs or analytics before making site changes. FanoutFox is a focused option for analysts who need empirical signals about generative search behavior.
