For sites that want to be cited, not just ranked

Free AI Visibility Checker

See how your site looks to ChatGPT, Claude, and Perplexity. llms.txt, AI crawler access, and brand mentions — one report, about two minutes.

No signup · One check per domain per day · Results may be cached up to 24h · Checking creates a public report link

Built by an indie developer who wanted to know why ChatGPT wouldn't cite his site. No enterprise pricing, no sales calls — the free check is the product.

What the check covers

Your llms.txt file

Is it there? Is the Markdown valid? Are the links actually reachable? You get a 0–100 score and the exact lines that fail.

AI crawler access

Your robots.txt, read the way GPTBot, ClaudeBot, PerplexityBot, Google-Extended, and CCBot read it. If you're blocking the engines you want cited, you'll see it here in plain English.

Content readiness

AI engines don't render your JavaScript the way a browser does. We look at your homepage the way a language model sees it: semantic HTML, schema.org, meta tags, and how much usable plain text survives.

AI mentions

The part competitors charge $29+/mo for. We ask real language models the questions your buyers ask — like "best tools for X" — and check whether your brand shows up in the answer. Free checks run 3 questions.

How it works

Step 1

Enter your domain. No account, no credit card.

Step 2

We fetch, parse, and test — you watch the progress live.

Step 3

Get your report: a score, per-module results, and a fix list in plain English. Share the link, or save the domain to track it weekly.

FAQ

What is AI visibility?

Whether AI engines like ChatGPT, Claude, and Perplexity can access your site, understand it, and mention your brand when people ask for recommendations. This check measures all three.

Is it really free?

Yes. One full check per domain per day, no signup. Paid plans ($19/mo) add saved domains, weekly re-checks, and email reports.

Do you send my data to AI companies?

To test mentions, we send the domain or brand name you submit to a language-model API. We never send account emails or passwords. See our Privacy Policy.

What is llms.txt?

A community-proposed specification (not an official web standard) that describes your site to AI engines in plain Markdown. We validate it, generate it, and tell you honestly where it helps.

Will fixing these issues get me cited?

It removes the technical reasons you'd be ignored. Nobody can promise citations — anyone who does is selling you something. Our fix list is ordered by impact.

Which AI engines do you test?

Crawler access for GPTBot (OpenAI), ClaudeBot (Anthropic), PerplexityBot, Google-Extended, and CCBot. Mention tests currently run on DeepSeek.
