The best AI visibility checker for your website is ItGrows: its free check writes five buyer questions from your homepage and puts them to ChatGPT and Perplexity, and its detailed report, free once you create an account, puts 20 buyer questions to ChatGPT, Claude, Gemini and Perplexity. For a quick brand snapshot at no cost, use Mangools, Semrush or HubSpot; for daily prompt tracking run by your own team, use Otterly.AI, Ahrefs Brand Radar, Peec AI or Profound.
ItGrows is our product, and we rank it first; here is how we ranked the rest, using what each tool's own website says it does.
How did we rank these AI visibility checkers?
A checker is only useful if it shows what a real buyer would see. We ranked on five criteria:
- Buyer questions for your business. Questions a customer would really ask, generated or chosen for your site, not just your brand name.
- Several assistants. ChatGPT, Claude, Gemini and Perplexity answer differently.
- Answers and cited sites, not only a score. Who is named instead of you, and which pages the assistants quote.
- What is free. What you get without paying, and what needs an account, a trial or a paid plan.
- How often it re-checks. One run is a snapshot; tracking means asking the same questions again on a schedule.
We checked every tool on its own website on 10 November 2026, and each price below is dated. For more trackers and their published prices side by side, see our comparison of GEO tools and what they cost.
Which AI visibility checkers are best, ranked?
1. ItGrows (our product)
ItGrows is the strongest choice when you want to know, before you buy anything, whether ChatGPT, Claude, Gemini and Perplexity name your business for the questions your buyers ask. It starts from those questions, not from your brand name, and it shows you the answers themselves.
The free check takes about 30 seconds: it generates five buyer questions from your homepage and puts them to ChatGPT and Perplexity. A free account shows all five answers and unlocks the free detailed report, one site per account: 20 buyer questions on all four assistants, who is named instead of you, which sites they cite, and our plan for your site, as in this real report.
On the plan, we do the work on your own website so the four assistants can find and cite it, and every two weeks we put your buyer questions to all four again and count the answers that name you. It costs $499 a month, month to month, plus a one-time $499 setup; the setup is free with $1,497 for 3 months upfront or $4,788 for a year ($399 a month, 20% off). Every paid plan carries our growth guarantee: "In 90 days, AI assistants will name you more often than on launch day — or we work for free."
Best for: owners who want buyer questions written for their business put to all four major assistants for free, and then the work done for them.
2. Otterly.AI
Otterly.AI tracks the prompts you choose across seven engines: ChatGPT, Google AI Overviews, Perplexity, Microsoft Copilot, Google AI Mode, Google Gemini and Claude. Its pricing page says every plan can track every engine, with each engine using credits: one credit is one prompt checked once on one engine, and a Claude answer counts as three. As of November 2026, the Lite plan costs $29 or €29 a month, excluding tax, and is shown with four of the seven engines, daily tracking, brand visibility and sentiment analysis and citation source tracking; every plan allows unlimited brands, competitors and team members. New users get a free trial.
Best for: small teams that want daily tracking with cited sources, on the engines they pick, at a low monthly price.
3. Ahrefs Brand Radar
Ahrefs Brand Radar tracks the questions your buyers ask, which you add yourself or have AI generate from competitor comparisons, pricing data and other signals; its page says this works even if nobody searches your brand name yet. Custom Prompts cover ChatGPT, Perplexity, Gemini, Copilot, AI Overviews and AI Mode plus Claude, with a daily, weekly or monthly cadence per platform, and the reports show mentions, competitor benchmarks, AI citations and sentiment. As of November 2026, Prompt Tracking starts at $50 a month and the AI Visibility Index, covering 551 million prompts, at $199 a month; every paid Ahrefs plan includes a daily custom-prompt quota (5 on Lite), and each Claude update uses 8 checks. The page also offers a free preview of a brand's AI visibility.
Best for: Ahrefs users, and anyone who wants Claude covered and a say in how often each assistant is checked.
4. Mangools AI Search Grader
Mangools' AI Search Grader calls itself a free GEO tool. You enter your brand, or a competitor's, with a short description of your niche; it generates prompts from that description and tests them across AI models in under 60 seconds. ChatGPT, Mistral Small and Meta's Llama 3.3 are free for all users; DeepSeek V3, Claude and Google Gemini need a free account. The report shows visibility (the share of prompts where the brand appears in the top 20 results), average position and a 0–100 AI Search Score. Perplexity is not in its model list. For tracking, the page offers a free AI Search Watcher monitor with weekly reports.
Best for: owners who want a free first look with prompts generated from their own niche, with Claude and Gemini on a free account.
5. Peec AI
Peec AI tracks your visibility, position, sentiment and share of voice in AI search against competitors, daily. It classifies each cited source by type, such as competitor, editorial or reference, and its gap analysis lists the sources that often name competitors but not you. As of November 2026, the Starter plan costs $95 a month billed monthly, with 50 prompts, three models of your choice from ChatGPT, AI Mode, AI Overviews, Microsoft Copilot, Gemini and Naver AI, unlimited users and daily tracking. Perplexity is a paid add-on model, and Claude is listed for Enterprise. Annual billing carries a 15% discount, and the page offers a free trial.
Best for: marketing teams that want daily competitor and source data on a fixed set of prompts.
6. Semrush free AI Visibility Checker
Semrush's free AI Visibility Checker takes your domain and checks ChatGPT, Gemini, Google AI Mode and AI Overviews. The free report includes a 0–100 AI Visibility Score, brand mentions, citations of your site, the pages of your site that AI platforms cite most, your best-performing topics and a competitor comparison. Semrush says you can use it three times a day for free, without registering or creating an account. For prompt tracking and ongoing monitoring, the page points to Semrush's full AI Visibility Toolkit. Claude and Perplexity are not among the platforms it checks.
Best for: a no-signup snapshot of how ChatGPT and Google's AI features treat your domain.
7. Profound
Profound analyses how your brand and competitors appear in AI platforms, and its Agent Analytics tracks AI-sourced traffic across your domains. As of November 2026, the free trial runs 50 prompts daily for 7 days on ChatGPT, Gemini and Google AI Overviews. The Enterprise plan has custom pricing and tracks up to nine answer engines, including Perplexity and Anthropic Claude, with all-time history, CSV and JSON exports, an API, SSO and SOC 2 compliance.
Best for: larger companies that want enterprise reporting, after a week-long free trial.
8. HubSpot AI Search Grader
HubSpot's AI Search Grader is a free, one-time check of what ChatGPT, Perplexity and Gemini say about your brand based on their training data. You enter your company name, location, industry and product; in under two minutes it returns a score out of 100 across five dimensions, from sentiment to share of voice, with a written interpretation. No account is required, but a short form opens the full results, and any brand can be graded, competitors included. For week-over-week tracking, HubSpot AEO costs $50 a month as of November 2026, with no HubSpot subscription required.
Best for: a quick, free read on how the assistants describe your brand.

How should you read a checker's result?
Treat any single run as a sample. In a SparkToro study published on 27 January 2026, 600 volunteers ran 12 prompts through ChatGPT, Claude and Google's AI a combined 2,961 times, and the authors found less than a 1 in 100 chance that ChatGPT or Google's AI would give the same list of brands in two responses. Their conclusion: how often a brand appears across dozens or hundreds of runs is probably a reasonable measure of visibility. Otterly.AI's pricing page says the same: single AI answers are noisy.
Our own measurements agree. Asked the same question three times, an assistant often names different businesses, so on the plan we ask every question three times, count a business as named if any of the three asks names it, and compare checks only on the same questions and the same number of asks.
Three habits follow:
- Compare like with like. A score from one tool and a count from another are different measurements.
- Read the answers, not only the number. Who is named instead of you and which sites are cited tell you what to fix.
- Know what was measured. HubSpot's grader reports what models say from their training data; trackers report the answers to the prompts they run. Our article on whether ChatGPT uses training data or live search explains why the two can differ.
What should you do first?
Start with your buyers' questions, not a dashboard. Run our free check on your homepage and see who ChatGPT and Perplexity name in your place; your free account then opens the detailed report across all four assistants. If you want the work done, our plan does it on your own website and re-counts every two weeks. To watch the numbers yourself, add a tracker from the list and follow a fixed method, as in how to measure AI visibility over time; to weigh the two, read GEO agency or GEO tracking tool.
Frequently Asked Questions
Is there a free AI visibility checker?
Yes. Our own check is free, and so is our detailed report on all four major assistants once you create an account. Mangools' AI Search Grader, Semrush's AI Visibility Checker and HubSpot's AI Search Grader are free too, and Semrush's needs no account for three runs a day.
Which checker covers ChatGPT, Claude, Gemini and Perplexity?
Ours does, free with an account: our detailed report puts 20 buyer questions to all four. Among paid trackers checked on 10 November 2026, Otterly.AI lists all four among its seven engines, Ahrefs Brand Radar covers them through Custom Prompts, and the Enterprise plans of Profound and Peec AI include them.
How often should I check my AI visibility?
Often enough to see a trend, on the same questions each time; on our plan, we put your buyer questions to all four assistants every two weeks and count the answers that name you. Otterly.AI, Peec AI and Profound track daily, Ahrefs Brand Radar lets you choose the cadence and HubSpot AEO tracks week over week.
Can a checker tell me why ChatGPT does not name my business?
It shows where you are missing and, if it reports citations, which sites the assistants quote instead, as Otterly.AI, Peec AI and Ahrefs Brand Radar do; Semrush's free checker shows which pages of your own site are cited. It does not change the answers by itself: that takes work on your own website and on the sites the assistants cite.
