Free AI Visibility Checker for ChatGPT and Perplexity

Your B2B buyers are asking ChatGPT, Perplexity, Gemini, Claude, and Google AI Overviews which vendors to shortlist. Most brands have no idea if they show up in those answers. Our free AI visibility checker tells you, in about two minutes.

Enter your domain and run a real check. See where your brand appears across ChatGPT, Perplexity, Gemini, Claude, and Google AI Overviews. Free, no credit card, first report in about two minutes.

Who can help you measure how often you appear in ChatGPT and Perplexity? We do. Hatter tests representative buyer prompts across the major AI search engines, records where your brand is mentioned, which sources get cited, which competitors show up, and how all of that moves over time. You get a baseline you can act on.

This is a real check, not a gated demo request. An anonymous visitor can run it and see their own result, including a zero if that is what the engines return.

What Does Hatter's AI Visibility Checker Measure?

Hatter's AI Visibility Checker measures your brand's AI visibility score, mention rate, answer prominence, cited sources, and competitor share of voice across major AI answer engines. It shows whether AI assistants mention, cite, compare, or omit your brand for the questions your buyers actually ask.

Here is what comes back in the report:

• AI visibility score based on how often and how prominently your brand appears
• Prompts tested and whether your brand appeared in each answer
• Answer prominence: cited first, buried below competitors, or absent
• Citations: which web sources the engines pulled in to build the answer
• Competitor share of voice: who else shows up for the same questions
• Trends over time, so you see what is working and what is slipping

Your AI visibility score

Your AI visibility score is a diagnostic signal, not a vanity metric. It tells you plainly whether you are present, absent, or underrepresented in AI answers for the questions that matter to your market.

Use it to prioritize what you focus on. A low score on high-intent prompts points you straight at the content, technical SEO, and authority work that will move the needle. A strong score tells you where to defend your position.

Prompts, mentions, and answer prominence

We measure visibility against real buyer-style questions, not a generic keyword list. The check builds prompts based on your category and how buyers actually ask for recommendations, comparisons, and solutions.

For each prompt, you see whether your brand appears and where. A mention buried under five competitors does little for consideration. A mention at the top of the answer influences the buyer's shortlist.

Citations and source patterns

Citations matter most in engines that show their sources. The check records which pages, publishers, directories, and third-party sources the engines cite when they answer.

Those patterns tell you what AI engines trust. If review sites and comparison pages get cited and your owned content does not, you know where the content and PR work needs to go.

Competitor share of voice

Competitor visibility is one of the most useful outputs here. The report shows which competitors appear when your brand does not, and how often the engines recommend them.

AI visibility is a competitive metric. Use it that way. If an assistant lists five vendors and you are not one of them, that gap is the first thing worth fixing. Our KPI guide breaks down how to read share of voice against your category.

How Does the Free AI Visibility Checker Work?

The free AI visibility checker works by testing representative buyer prompts across major AI answer engines, recording where your brand and competitors appear, and tracking those results over time. Because AI answers are dynamic, reliable measurement comes from repeated sampling, not a single query.

Our tool runs simulations on the AI assistants to understand what gets cited and how. We run those simulations to measure it.

1. We build a representative prompt set for your category.
2. We run those prompts across ChatGPT, Perplexity, Gemini, Claude, and Google AI Overviews.
3. We record brand mentions, competitor mentions, citations, and answer positioning.
4. We rerun the check on a cadence so you can see whether visibility is rising or falling.

Representative prompt sets

Prompts matter more than a keyword list because buyers ask questions, not keywords. Those questions vary by category, intent, and research stage.

A prompt like "best vendors for X" behaves differently from "alternatives to competitor Y" or "pricing for Z." We build the set to reflect how real buyers ask, so you measure visibility where commercial discovery happens.

Cross-engine simulations

ChatGPT is not the whole market. The check spans ChatGPT, Perplexity, Gemini, Claude, and Google AI Overviews because each engine behaves differently.

Perplexity exposes citations directly. ChatGPT visibility often depends on answer inclusion and the sources the model can access. Each engine may cite different sources and recommend different brands, so cross-engine coverage gives you the full picture.

Mentions, citations, and competitor results

During each run we collect the raw signals:

• Whether your brand appears
• Which competitors appear
• Which sources the engine cited
• Where you sit inside the answer
• Whether the answer category matches your market

Ongoing visibility tracking

A snapshot is useful. Trend data is strategic. AI citations can change 40 to 60% month to month for the same prompt, so a single check can mislead you.

Rerunning prompts as an AI visibility tracker smooths out that noise. It separates real movement from one-off answer variation and shows which content changes are actually working.

What Can an AI Visibility Check Tell You, and What Can't It Tell You?

An AI visibility check can show how often your brand appears for sampled buyer prompts across major AI engines, but no tool can measure every possible AI answer, so reliable tracking requires repeated sampling over time. Treat it as directional diagnosis, not a perfect universal count.

We are direct about this because a skeptical marketing leader deserves the truth. Measurement is diagnosis. Execution is what changes visibility.

What repeated sampling can measure

Run the prompts on a cadence and you get a trustworthy read on:

• Directional visibility across engines
• Mention rate over time
• Competitor movement
• Citation patterns
• Improvements after content or authority work

Why no tool can count every AI mention

AI answers vary by prompt wording, location, timing, personalization, and model updates. No AI visibility audit can capture every answer every user will ever see, and any tool claiming otherwise is overselling.

The goal is not a perfect universal count. The goal is a reliable framework that shows where your visibility is improving or falling.

How to interpret the results responsibly

Treat the first report as a baseline. Look for repeated patterns, not isolated answers. Then use the results to prioritize your content, technical, and off-site work rather than reacting to a single odd response.

How Should You Use Your AI Visibility Score?

You should use your ai visibility score as a baseline for deciding which prompts, pages, sources, and competitor gaps deserve the next round of SEO and AEO work. It turns an interesting diagnostic into a prioritized backlog.

Diagnose missing buyer questions

Look at the prompts where competitors appear and you do not. Those are content gaps, and the ones with commercial research intent matter most. Each is a chance to create or improve answer-ready content.

Find weak citations

AI engines lean on trusted third-party sources. If your citations are thin, you may need stronger owned content, directory presence, comparison pages, or digital PR. Citation analysis shows which sources influence the answers you want to win.

Track whether changes are working

Rerun the prompts after you ship content changes. Watch competitor movement. Visibility trends validate your strategy and tell you when to double down or change course. This all feeds our own strategy, where we use the data to chase the gaps.
