Your brand is being discussed in AI search right now—and you probably have no idea what's being said. Every time someone asks ChatGPT for a product recommendation, prompts Perplexity for a comparison, or queries Claude for advice in your industry, AI is either recommending you, recommending your competitors, or leaving you out entirely.
Today, we're launching the PromptAlpha Visibility Checker—a free tool that lets you see exactly how your brand appears across five major AI search engines in under 60 seconds.
Why You Need an AI Visibility Checker
Traditional SEO tools tell you where you rank on Google. But they can't tell you whether ChatGPT recommends your brand, whether Claude describes your product positively, or whether Perplexity cites your website as a source.
This blind spot is growing fast. AI-assisted search is no longer a niche behavior—ChatGPT alone processes over 37.5 million queries per day, and that number is accelerating. Perplexity, Claude, Gemini, and Grok are adding millions more. For many high-intent commercial queries, users are skipping Google entirely and going straight to AI.
If you're not tracking your AI visibility, you're operating with incomplete data about your brand's digital presence.
What the Visibility Checker Measures
The PromptAlpha Visibility Checker analyzes your brand across all five major AI platforms and returns four key metrics:
Visibility Score
Your visibility score measures the percentage of AI engines that mention your brand when asked a relevant query. If your brand appears in 4 out of 5 AI responses, your visibility score is 80%.
This is the most fundamental metric. A score below 40% means most AI engines don't consider your brand relevant enough to mention—even when users are asking directly about your category.
Share of Voice
Share of voice measures your brand's proportion of all brand mentions across AI responses. If AI mentions five brands total and yours appears three times, your share of voice is about 20%.
This metric reveals your competitive positioning. A high visibility score with a low share of voice means AI knows you exist but gives more airtime to competitors.
Average Position
Average position tracks where your brand appears in AI responses. Position #1 means you're the first brand mentioned; position #4 means three competitors are named before you.
Being mentioned first matters. Users disproportionately remember and act on the first recommendation in an AI response, just as they click the first result in a Google search.
Citation Share
Citation share measures what percentage of sources cited by AI engines point to your website. If AI cites 12 sources across all responses and 3 link to your domain, your citation share is 25%.
This metric connects AI visibility to web traffic. A high citation share means AI is not just mentioning your brand—it's actively sending users to your website.
How the Visibility Checker Works
Using the tool takes three steps:
Step 1: Enter Your Website
Type your website URL into the checker. The tool automatically identifies your brand name, domain, industry, and description using AI extraction—no manual setup required.
Step 2: Choose a Search Query
The checker generates industry-specific query suggestions based on your brand. These are the kinds of questions real users ask AI when searching for products or services like yours. You can also enter a custom query.
Step 3: Get Your Results
Within 30–60 seconds, the checker queries ChatGPT, Claude, Perplexity, Gemini, and Grok simultaneously. You'll see:
- Your four metric cards (visibility, share of voice, average position, citation share)
- Individual AI engine responses with your brand highlighted where mentioned
- Sources cited by each AI engine, with links back to the originating websites
- Competitor brands detected across all responses
- Optimization tips tailored to your specific results
Who Should Use the Visibility Checker
Marketing Teams
If you're responsible for brand awareness or lead generation, the visibility checker reveals a channel you're likely not tracking. Discovering that AI recommends your competitor 80% of the time is the first step toward fixing it.
SEO Professionals
Traditional SEO and GEO (Generative Engine Optimization) require different strategies. The visibility checker helps you understand which of your SEO investments are also paying off in AI search—and where the gaps are.
Founders and Product Leaders
Before investing in AI search optimization, you need a baseline. The checker gives you a concrete snapshot of where your brand stands today so you can measure improvement over time.
Agency Teams
Agencies managing multiple brands can use the checker to quickly audit AI visibility for clients during pitches, onboarding, or quarterly reviews. It's a compelling data point that most competitors aren't tracking yet.
What Your Results Mean
Once you have your results, here's how to interpret them:
| Metric | Strong | Needs Work | Action Required |
|---|---|---|---|
| Visibility Score | 60%+ | 30–59% | Below 30% |
| Share of Voice | 25%+ | 10–24% | Below 10% |
| Average Position | #1–2 | #3–4 | #5+ |
| Citation Share | 15%+ | 5–14% | Below 5% |
If your visibility score is below 30%, most AI engines don't mention your brand at all. This typically means your brand lacks sufficient online authority signals—authoritative content, third-party mentions, and structured data.
If your share of voice is below 10%, competitors dominate the conversation. Even when AI mentions you, it's giving significantly more attention to others in your space.
If your average position is #4 or lower, you're being mentioned as an afterthought. Users rarely act on recommendations buried late in an AI response.
If your citation share is below 5%, AI is talking about your brand but not sending traffic to your site. This often means your content isn't structured in a way that AI can easily cite.
How to Improve Your AI Visibility
The visibility checker is a diagnostic tool—it shows you where you stand. Here's what to do with the results:
1. Create AI-Extractable Content
AI engines pull information from content that's well-structured, factual, and authoritative. Focus on:
- Clear product descriptions with specific features and comparisons
- FAQ pages that directly answer common industry questions
- Data-driven content with original statistics and research
- Comparison pages that objectively position your brand against alternatives
2. Build Authoritative Citations
AI engines prioritize brands that appear on trusted third-party sources:
- Industry publications and review sites (G2, Capterra, TrustRadius)
- Media coverage and press mentions
- Wikipedia and knowledge bases
- High-authority blogs and educational sites
3. Optimize Your Technical SEO for AI
Several technical factors influence whether AI can discover and cite your content:
- Schema markup that makes your content machine-readable
- Clear page structure with logical heading hierarchies
- Fast page load times (AI crawlers deprioritize slow sites)
- Consistent NAP data (Name, Address, Phone) across the web
4. Monitor Continuously
A single check gives you a snapshot, but AI visibility changes constantly as models are updated, competitors publish new content, and user behavior shifts. For ongoing tracking, consider setting up continuous monitoring with PromptAlpha.

FAQs
Is the visibility checker really free?
Yes. The visibility checker is completely free to use with no account required. You can run multiple checks per day to test different queries for your brand.
How accurate are the results?
The checker queries each AI platform in real time using the same APIs that power their consumer products. The results you see are what real users would see if they asked the same question right now.
Which AI platforms does it check?
The checker tests across five platforms: ChatGPT (OpenAI), Claude (Anthropic), Perplexity, Gemini (Google), and Grok (xAI). These represent the vast majority of AI search traffic today.
How is this different from a regular SEO audit?
An SEO audit tells you how you rank on Google. The visibility checker tells you how AI recommends your brand in conversational responses. These are fundamentally different—a brand can rank #1 on Google but be completely absent from AI search results, and vice versa.
Can I check competitor brands?
You can enter any website URL to check any brand's AI visibility. This makes it useful for competitive analysis—check your own brand, then check your top competitors to see how you compare.
How often should I check my visibility?
For a quick pulse check, once a month is a reasonable starting point. If you're actively optimizing for AI search, weekly checks help you measure the impact of your efforts. For continuous, automated tracking, PromptAlpha's full platform monitors daily.
