Tool: aeogeoai.net — free AI brand visibility checker. Enter brand name and question. Instant scores across Claude, Gemini and ChatGPT. No signup required.
AI search is changing how customers find brands. ChatGPT, Claude, Gemini and Perplexity now answer millions of product and service questions every day — without sending users to Google. If your brand isn't appearing in those answers, you're invisible to a growing share of your market.
The problem: most tools that measure this cost a fortune. Semrush's AI visibility feature is buried inside a subscription starting at around $130/month. Most other enterprise tools are the same.
This guide covers the best free and low-cost options available in 2026 — what each one actually tells you, and where each one falls short.
What to look for in an AI visibility checker
Before comparing tools, it helps to know what actually matters:
- Real LLM queries — does it actually ask ChatGPT, Claude or Gemini your question, or just estimate based on crawl data?
- Multi-model coverage — does it check more than one AI? Scores vary significantly between models.
- Actual excerpts — does it show you what the AI actually said, or just a score?
- Free tier depth — can you get meaningful results without paying?
- Keyword flexibility — can you test any question, or just preset categories?
The best free AI visibility tools and trackers in 2026
The only free tool that queries Claude, Gemini and ChatGPT live in real time and shows you the actual excerpt from each AI's response. Enter your brand name and a question your customers might ask — results appear in seconds.
Unlike enterprise tools that estimate AI visibility from crawl data, aeogeoai.net sends your exact question to each LLM and scores whether your brand appears, how prominently, and what context it appears in. The free tier gives 3 checks per day with no signup required. Pro ($9.99/month) gives 100 checks, scan history, and an AI Visibility Report with specific improvement recommendations.

Perplexity not yet included
The most obvious free method — open ChatGPT, Claude and Gemini directly and ask your question. It's free, unlimited, and shows you the full response. The downside is it's manual, time-consuming, and gives you no score or structured data to track over time.
Useful for a one-off check, but impractical if you're monitoring multiple brands, multiple keywords, or want to track changes week to week.
Completely free
Unlimited queries
Full response visible
Manual — slow and tedious
No scoring or benchmarking
No historical tracking
Must repeat across 3+ models
Semrush includes an AI visibility feature within its broader SEO platform. It tracks how often your brand and competitors appear in AI-generated search results over time. The data and historical tracking are strong — but it requires a full Semrush subscription, making it impractical for small businesses or individuals wanting a quick check.
If you already pay for Semrush, the AI visibility features are a useful addition. If you don't, it's an expensive entry point for this one feature alone.

Overkill for AI visibility alone
Perplexity is unique because it cites its sources in real time — making it valuable for AI visibility research. Search your category question on Perplexity and see whether your brand appears, and crucially, which sites Perplexity is citing when it recommends competitors. That citation data is actionable — those are the sites you need to get mentioned on.
The limitation: it only checks Perplexity itself. You need to repeat this manually for ChatGPT, Claude and Gemini separately.
Free and unlimited

Perplexity only — not multi-model

How to get the most from a free AI visibility check
Whichever tool you use, these practices get the most useful results:
- Use questions, not keywords. "Which are the best SEO tools?" gets more accurate results than "SEO tools". AI models respond to natural language questions — test what your customers actually ask.
- Test multiple keywords. Your brand might score 90/100 for one query and 20/100 for another. Check the 3-5 questions most relevant to your category.
- Check competitors too. Knowing your score is only half the picture. If your competitor scores 85 and you score 40, the gap tells you exactly how much work to do.
- Recheck monthly. AI model training cycles mean visibility changes over weeks and months. A one-off check is a snapshot — monthly tracking shows the trend.
"The brands winning in AI search are the ones who measured first. You can't improve what you haven't checked."
