Free AI Visibility Checker

What an AI visibility checker tells you

A checker answers the first, most urgent question: am I even in the answer? It runs category prompts across AI engines and reports whether your brand is mentioned, whether it’s cited as a source, and which competitors are named in your place. It’s the fastest way to turn a vague worry — “are we invisible to AI?” — into a concrete baseline.

A checker is a snapshot, not continuous monitoring. For trends over time, see the AI visibility tracker; for the full picture of what to measure, start with AI visibility.

The reason a fast baseline matters is timing. AI search surfaces are still forming the habits that will decide which brands get cited for years — which sources they trust, which pages they pull from. Brands that measure now and fix early are setting those defaults; brands that wait will be trying to displace incumbents the engines have already learned to prefer. A free check costs nothing but a few minutes, and it converts an open-ended worry into a specific, prioritised to-do list.

How the free check works

1. Enter your brand or domain. No account needed to see a baseline.
2. We scan the engines. Category prompts run across ChatGPT, Perplexity, Gemini and Google AI Overviews.
3. You get your result. Mentions, citations and where competitors show up instead of you.
4. Decide what to fix. The result points to the structural gaps worth closing.

How to read your checker results

A baseline scan returns three things worth understanding before you react to them:

• Mention vs citation. Being named in an answer is not the same as being linked as a source. A brand can be mentioned often yet rarely cited — or cited as a source without being recommended by name. The checker separates the two because they have different fixes.
• Who appears instead of you. The most useful line in any result is the competitor list. If the same two or three rivals keep surfacing for your category prompts, that’s your real benchmark — not an industry average.
• Which prompts trigger you. You may be strong on broad definitional queries and absent on high-intent commercial ones (“best tool for X”). Where you show up matters as much as how often.

A thin result isn’t a verdict — it’s a starting map. It points to which prompts and which content types to work on first.

Checker vs full audit: what a baseline does and doesn’t do

A checker is deliberately narrow. It answers “am I present?” fast, across a sample of category prompts, on a single run. It does not smooth out the variance between runs, track movement over time, or test the full breadth of prompts a buyer might use. Those are jobs for continuous tracking and a deeper audit. Think of the free check as triage: it tells you whether you have a visibility problem and roughly how big, so you can decide whether the deeper work is worth it. For ongoing monitoring, the AI visibility tracker re-runs your prompt set on a schedule; for the full set of metrics behind the scan, see AI visibility metrics.

Why your brand might not show up

If the check comes back thin, the cause is usually structural and fixable: content the engine can’t parse, weak entity signals, no llms.txt, or a lack of quotable, sourced authority. The checker shows the symptom; closing the gap is where the AI visibility tool takes over — measurement into action through agents for WordPress, Shopify, Drupal and Chrome.

What to do after the check

A baseline is only valuable if it changes what you do next. The common, fixable causes of a thin result map to four moves, roughly in order of effort-to-impact:

• Add answer-first passages. For each prompt you missed, make sure a page on your site answers that exact question clearly in its first lines — the passage an engine can lift and cite.
• Fix structure and schema. Clear headings, lists and valid schema help an engine parse and trust your content. Invalid or missing schema is a quiet, common blocker.
• Strengthen entity signals. A consistent brand name, an about page and structured data help engines understand what you are and which queries you belong in.
• Publish or claim an llms.txt. It signposts AI crawlers to your most citable pages — still rare enough in most categories to be an edge.

Re-check after each change. Because answers vary between runs, a single re-scan isn’t proof — but a trend across several is. That’s where continuous tracking takes over from the one-time check.

Is it really free?

Yes — the baseline scan is free with no credit card. CapstonAI is a measurement platform, not an agency: the checker shows you where you stand, and you decide what to do next. Paid plans are available for continuous tracking and action.

The free check is built to answer one question well — am I present? — not to lock you into anything. There’s no obligation to upgrade, and the baseline you get is genuinely useful on its own: a named competitor list, the prompts that trigger you, and the gap between being mentioned and being cited. Where the paid platform earns its place is in the work the free scan can’t do: re-running your prompt set on a schedule so you can tell a real trend from run-to-run noise, tracking competitors over time, and turning each gap into a concrete fix through the agents. Run the free check first; only move up when you’ve decided the deeper work is worth it.
