Free AI visibility checker
An AI visibility checker is a free tool that measures whether AI systems can reach and read your website, by fetching your homepage as GPTBot, ClaudeBot, PerplexityBot, and four other AI crawlers and reporting exactly what each one got back.
See what ChatGPT, Claude and Perplexity can actually read on your site.
Every reading is scored out of 95. Ten seconds, no account, nothing to install.
The email is required because the report is delivered as a link to the address you enter. Free, no account, about ten seconds.
What the check tells you
- Each AI crawler receives either a 200, meaning your homepage is readable, or a 403, meaning something is turning that crawler away.
- Your robots.txt either allows or disallows each crawler token, and the report names every directive that applies.
- Your homepage either has readable text without JavaScript, or it is empty to a crawler that does not run scripts.
- Structured data types present on the page are listed, and the types you are missing are named beside them.
What it checks
- AI crawler accessYour homepage, fetched under each crawler user agent. A 403 means a firewall is turning that crawler away.
- robots.txt policyEvery directive, read per token. The usual finding is a disallow nobody meant to write.
- Renders without JSHow much text is in the raw HTML. Most AI crawlers do not run JavaScript.
- Structured dataWhich JSON-LD types you have, and which of the ten that matter you are missing.
- sitemap.xmlPresent and served as real XML, or missing.
- llms.txtPresent, or missing. It states in plain language what your site is for.
- agents.mdPresent, or missing. It is the same idea for agents that arrive to act.
- On-page hygieneTitle length, meta keywords, H1 count, heading order.
Where the data allows, the report also covers what an assistant currently says about your business. It reports findings; it does not write you a content plan.
What comes back
An excerpt from the sample report, for a domain that does not exist. The crawler table is the part people read first, because a status code is a fact rather than an estimate.
| Crawler | Live fetch | robots.txt |
|---|---|---|
| GPTBot | 200 | allowed |
| OAI-SearchBot | 200 | allowed |
| ClaudeBot | 403 blocked | allowed |
| Claude-SearchBot | 200 | allowed |
How this differs from a GEO audit tool
A GEO audit works backwards from answers: it asks an assistant a set of questions and scores you on whether you were mentioned. That measures an outcome, which is useful, but a miss does not tell you why you were missed.
This works forwards from access. If a crawler gets a 403, or your pages are empty without JavaScript, no amount of content strategy changes what an assistant can say about you. Fix the floor first, then measure answers.
Questions
What is an AI visibility checker?
A tool that measures whether AI systems can reach and read your site. This one fetches your homepage as each major AI crawler and reports what came back.
Is it free?
Yes. No charge, no card, no account.
Do I need to install anything?
No. Every check reads a public signal, so nothing is added to your site.
Does re-running overwrite my previous report?
No. Each run creates a fresh report at its own link, so you can compare two dates by opening both.
What is a good score?
Above 85 is strong, 70 to 84 is solid, and below 50 means something is actively blocking you. The maximum is 95, not 100: the last five points are the crawl history only your own server logs can show.
Which AI engines are checked?
Seven: GPTBot and OAI-SearchBot, ClaudeBot and Claude-SearchBot, PerplexityBot, CCBot, and the Google-Extended policy that governs Gemini.
What happens to the data I submit?
Your email is stored so the report can be sent to it, and the report stays at its link. The check itself reads only public signals from the domain you enter.
How is AI visibility measured?
AI visibility is measured in separate steps, and each step is a different number. A mention is not a visit, a visit is not a click, and a click is not a sale. This checker measures the first step, access, which is whether an AI crawler can reach and read your pages at all. Server-side tracking measures the steps after that, because only your own server sees which crawler arrived and which visitor followed.
How do I track AI visibility over time?
One check is a snapshot of a single moment, so it cannot show a trend on its own. Each run creates a new report at its own link, so you can open two dates side by side and compare them. For continuous tracking, start a free Kymo trial.
Is there a free AI visibility tracker?
Yes. This checker is free with no account and no card, and it reports crawler access, robots.txt policy, rendering and structured data for any domain. A one-time check cannot tell you which crawlers actually arrived afterwards, how often they came, or which pages they took.
This is one reading. Kymo gives you the rest.
The check shows what a crawler could read today. Kymo shows which ones actually came, how often, and which pages they took, alongside your human traffic. Cookieless, no banner, and crawler tracking never counts against your plan.

Kymo is cookieless: no raw IPs and no human visitor’s user-agent string. For bot traffic the crawler’s user agent is recorded, because identifying the crawler is the point. Full detail on the privacy page. Every crawler named above is documented in the AI crawler directory.
