Competitor AI Visibility Gap Tool

See the buyer prompts where a competitor wins in ChatGPT and you don't — scored head-to-head. Free, instant, no signup.

Where are you losing to competitors in AI answers?

An overall visibility score tells you that you're behind — not where. This free competitor AI visibility tool scores you and a competitor on the exact same ChatGPT answers and shows the buyer prompts where they're recommended ahead of you. Those prompts are your highest-leverage fixes.

How the gap analysis works

  1. Enter your website and one competitor.
  2. We ask ChatGPT the buyer questions in your category and read its ranked recommendations.
  3. We score both brands from the same answers and surface the prompts where the competitor wins.

Why ChatGPT favours one brand over another

ChatGPT doesn't rank your pages — it answers from the sources it trusts: comparison and “best X” articles, review sites like G2 and Capterra, Reddit threads and clear, well-structured content. When a competitor shows up more across those sources, ChatGPT recommends them first. Closing the gap is the work of generative engine optimization (GEO).

From one competitor to your whole market

This check compares one competitor on a snapshot. Visiblee benchmarks you against your entire competitive set across ChatGPT, Gemini, Perplexity and Google AI Mode, tracks every prompt over time, and shows the citations and sources driving each answer — with alerts when a competitor gains ground. Run the free comparison, then start a full scan.

Frequently asked questions

What does the Competitor AI Visibility Gap tool do?

It asks ChatGPT the buyer questions in your category, then scores both you and a competitor on the same answers — and shows the exact prompts where the competitor is recommended ahead of you. You see where you're losing, not just an overall number.

Is it free?

Yes — compare against one competitor free, no signup. To compare against multiple competitors across every AI engine and track it over time, start a free Visiblee scan.

How is the head-to-head score calculated?

For each buyer prompt we check whether ChatGPT recommends you and the competitor, and how highly it ranks each. We average that into a visibility score for both brands from the same set of answers, so it's a fair, like-for-like comparison.

Why does ChatGPT recommend my competitor over me?

ChatGPT builds answers from the sources it trusts — comparison pages, review sites, Reddit and well-structured content. If a competitor appears more across those sources, ChatGPT ranks them higher. Closing the gap means improving your presence where those answers come from.

Can I compare more than one competitor?

This free tool compares against one competitor. Visiblee benchmarks you against your whole competitive set across ChatGPT, Gemini, Perplexity and Google AI Mode, and tracks the gap over time with alerts.
