Free AI visibility checker
Use this AI visibility checker to see whether answer engines can read your site and whether ChatGPT, Gemini, and Perplexity name your brand. The instant check grades AI-readiness. The trial scan shows where you sit in the answer, who appears instead, and your share of voice.
Grade your site's AI-readiness
Enter your site and we check the signals that decide whether AI answer engines can read and cite you - llms.txt, structured data, AI-crawler access, answer-formatted content, and more. Instant, free, no email.
We read your server-rendered HTML - the same thing most AI crawlers see · the grade itself stores nothing
What a free AI visibility checker shows you
Your buyers now ask an AI before they reach your site. They type a buying question into ChatGPT, Gemini, or Perplexity and read one confident answer that names two or three brands. If the AI does not name you, you are not in the consideration set - and nothing in a normal marketing stack measures that. A free AI visibility checker is the fastest honest way to find out where you stand.
This page is both an AI visibility checker and a starting point for a real monitor. The instant site grade checks whether your pages are readable and citable. The trial answer scan checks the answer itself: whether ChatGPT, Gemini, and Perplexity name your brand, where you appear, and which competitors take the spot.
There are two honest layers to this, and they answer different questions. The instant grade above checks your own site's AI-readiness - the structure and signals that decide whether engines can read and cite you (llms.txt, schema, crawler access, FAQ content). It's real, deterministic, and free, and it tells you what to fix. But your site's readiness is not the same as what the AI actually says about you. For that - whether ChatGPT names you or a competitor, in what position, with what sentiment - you run the trial scan and report. Here is what that read tells you:
Site AI-readiness vs answer visibility
What an AI visibility audit should include
A useful AI visibility audit needs enough evidence to explain both discoverability and the answer buyers see. A score without the inputs behind it is not an audit. Look for these six parts:
- Technical readiness. Crawler access, structured data, clear titles, and answer-ready sections.
- Buyer prompt set. Category, comparison, alternative, and problem-aware questions your prospects ask.
- Answer presence. Whether the brand appears, where it appears, and how the engine describes it.
- Competitive context. Which brands appear instead and how share of voice is distributed.
- Citations and sources. The pages, reviews, documentation, and discussions supporting the answer.
- Prioritized actions. A dated baseline and the first page, proof, or distribution gaps to fix.
Named or not
The first thing you learn: does the AI mention your brand at all for the prompt, or does it answer the buying question without you in it.
Position
If you are named, where you land - first recommendation, an also-ran in a list, or a footnote. Position inside the answer is close to position inside the buyer's shortlist.
Sentiment
How the model talks about you - the framing it puts around your brand, which is what the buyer reads before they ever click.
Who's named instead
The competitors the engine recommends in your place - often not the list on your battlecard, but the one the AI actually surfaces for your prompts.
Share of voice
How often you are named versus those competitors across the answers, turned into one number you can track instead of a pile of scattered screenshots.
How to run the check in three steps
The whole point of an AI visibility checker is that it should not cost you a week of setup. There is no engineering ticket and nothing to wire up. Three steps and your first read is in front of you:
01 Add your brand
Tell Sonarvue your brand name and a competitor or two you want to measure against. No tag, no SDK, no site change - Sonarvue reads public AI answers, so there is nothing to install.
02 Pick the prompts
Choose the buying questions your customers actually ask an AI before they reach your site - the kind of 'what's the best X for Y' a prospect types into ChatGPT or Perplexity. Start with a handful; you can refine them later.
03 Read in minutes
Sonarvue captures the real answer from each engine and judges it: are you named, where you sit, how the model talks about you, and which rivals it lists instead. Your first read completes in minutes, not after an engineering ticket.
Why it is a trial scan, and what it includes
Sonarvue is in beta, and the honest first move in this category is to look at the answers before you commit to a monitor. The trial scan covers one brand, one scan, and one report with brand presence, named competitors, a share-of-voice snapshot, and first fixes. It is not ongoing free monitoring.
When you need ongoing monitoring, Starter is $49/mo for 25 tracked prompts, one brand, three members, and all eight default engines. Growth is $149/mo for 100 prompts, up to five brands, ten members, GSC, competitor radar, and exports. Scale is $599/mo for 500 prompts, up to 15 brands, 50 members, workspaces, API, SSO, and agency reporting.
What the free check does not do
Honesty matters more than a tidy pitch, so here are the limits. The instant checker reads your public server-rendered HTML, but it does not access analytics or customer data and it is not a full page-speed or on-page SEO audit. The trial monitor reads the public AI answer surface and measures what models say about you, not your traffic. If your buyers do not yet research with AI, the signal will be thin. The trial report is the baseline; a paid monitor tracks the answer over time.
When to use a visibility checking tool
Use a visibility checking tool when a buyer might ask an AI for a shortlist before visiting your site. The AI visibility checker gives you a fast read on the signals you control. For a broader toolkit, see the free AI visibility tools. If you are comparing vendors, read the best AI visibility tools guide or the focused comparison of free AI visibility checkers.

Frequently asked
What is an AI visibility checker?
An AI visibility checker shows whether AI answer engines can read, understand, mention, and cite a brand. Sonarvue checks two layers: site AI-readiness signals such as schema, llms.txt, and crawler access, plus a trial answer scan that shows whether ChatGPT, Gemini, and Perplexity name your brand or competitors.
What should an AI visibility audit include?
An AI visibility audit should cover technical readiness, representative buyer prompts, answer presence and position, brand framing, competitors, share of voice, cited sources, and a prioritized fix list. It should also save a dated baseline so later runs can prove whether visibility changed.
Is the AI visibility check free?
Yes. Sonarvue's free AI visibility check starts a seven-day trial with 10 tracked prompts and one generated keyword strategy. Starter is $49/mo for 25 prompts, one brand, and three members. Growth is $149/mo for 100 prompts, up to five brands, ten members, GSC, competitor radar, and exports.
Do I need to install anything?
No. The instant readiness checker fetches public server-rendered HTML, and the answer scan reads public AI answers. Neither requires a tag, SDK, analytics access, or customer data. You provide your brand and buyer prompts, and the first read completes in minutes.
Which engines does it check?
The trial scan checks an initial answer set across ChatGPT, Gemini, and Perplexity. Starter and Growth extend ongoing coverage to all eight: ChatGPT, Claude, Gemini, Perplexity, Google AI Overviews, Microsoft Copilot, Grok, and Kimi, scored together on one timeline.
What is the difference between an AI visibility checker and an AEO tracking tool?
An AI visibility checker gives a baseline: can the engines read your site, and do they name your brand for a first prompt set? An AEO tracking tool monitors that answer visibility over time, across a fixed cadence, so you can see share-of-voice movement, competitor changes, lost citations, and which content fixes worked.
Run your free AI visibility check now
Run the free AI visibility checker first, then use the trial scan to see the answer itself. You will know, on day one, whether the AI shortlists you or a competitor for the questions that drive your pipeline - and that is usually the most useful thing a marketing team learns all quarter, even when the answer stings.
