Bottom Line Up Front
To check your AI engine visibility for free: run 10 target queries in ChatGPT, Gemini, and Perplexity and record whether your brand appears. Count your mentions divided by total brand mentions — that is your AI Share of Voice baseline. Or use Optymia's free AI Visibility Score to get an instant automated score at optymia.xyz.
What Is an AI Engine Visibility Checker?
An AI engine visibility checker is a tool that measures how often your brand appears in AI-generated responses across ChatGPT, Gemini, Perplexity, and other AI search engines. It gives you a measurable score — your AI Share of Voice — rather than the vague sense that "we might appear sometimes."
Without a systematic checker, you are flying blind. Brands typically overestimate their AI visibility (because they occasionally see themselves in AI results) or underestimate it (because they only tested 2-3 queries). A proper checker runs 50+ queries and tracks results over time.
Method 1: Manual Check (Free, 30 Minutes)
This works well for an initial baseline. Here is the exact process:
- Build a 20-query test set. Include: "best [your category] for [use case]", "what is [your brand]", "[your brand] vs [competitor]", "how to [solve your problem]", "top [your category] tools 2026"
- Run each query in ChatGPT (GPT-4), Google Gemini, and Perplexity. Use fresh browser sessions or incognito mode. Record results in a spreadsheet.
- For each response, note: Is your brand mentioned? Is the description accurate? Which competitors appear?
- Calculate your AI SoV: (Your brand mentions / Total brand mentions across all queries) × 100
- Benchmark against competitors: Run the same queries and record which brands appear most frequently.
Method 2: Optymia Free AI Visibility Score (Instant)
Optymia's free AI Visibility Score automates this entire process. Enter your domain at optymia.xyz, and within 30 seconds you get:
- An AI Visibility Score from 0-100
- Your estimated AI mention rate across target queries
- The number of semantic gaps (queries where competitors appear but you do not)
- How many competitors are outranking you in AI search

What Your Score Means
0-30 (Needs Work): Your brand has minimal AI entity footprint. AI systems likely cannot reliably identify or recommend you. Priority: Wikidata entity creation, Organization schema, G2 profile.
31-55 (Developing): Some AI visibility but inconsistent. You appear in broad queries but miss use-case-specific ones. Priority: direct-answer content, FAQPage schema, citation velocity.
56-75 (Good): Solid AI presence in your core category. Focus on expanding to adjacent query contexts and competitor comparison queries.
76-100 (Authority): Strong AI visibility. Focus on maintaining and monitoring for algorithm changes.
How Often to Check Your AI Visibility
Weekly monitoring is the standard for serious brands. AI systems update their knowledge bases continuously, and a competitor gaining new citations or publishing optimized content can affect your AI SoV within weeks. Monthly monitoring is the minimum for any brand that cares about AI search performance.
