The easiest free AI visibility audit combines a website scan that checks whether AI assistants can read your site with a manual test where you ask ChatGPT, Gemini, Perplexity and Claude the questions your customers ask. CoreTxt offers the scan as a free AI Visibility Snapshot, with no credit card and a score out of 100.
AI visibility audit: a structured test of whether AI assistants can find, understand and recommend your business, ending in a ranked list of fixes.
Where can you find a free AI visibility audit?
There is no single free tool that does everything, so combine a website scan with a manual test.
| Option | What it checks | Cost | Limits |
|---|---|---|---|
| CoreTxt AI Visibility Snapshot | Crawler access, structured data, llms.txt, readiness score and main blocker | Free, no card | Technical check. Does not ask the assistants questions |
| Manual test in the assistants | Whether you are named for real customer questions | Free plus your time | Answers vary, so repeat runs |
| Bing Webmaster Tools AI Performance (beta) | When Copilot and Bing AI cite your pages | Free | Microsoft only. No clicks or competitors |
| Your own analytics | Visits from AI assistants as referrals | Free | Many readers never click |
What to do next: Run the free Snapshot, then follow the test guide. We built the Snapshot, so weigh that when you read this guide.
What does the CoreTxt Snapshot give you?
A readiness score out of 100, whether AI crawlers can reach your site, your structured data and llms.txt status, and your biggest single blocker.
You enter your business name, website, service area and industry. It takes about a minute to start and needs no credit card.
What can a free tool tell you?
It can tell you whether your site is technically readable and which obvious gaps to close first, but not why a competitor is chosen.
It cannot tell you how your mention rate compares across many questions or how it changes over time. Repeating the test monthly matters more than any one result.
What should you look for in any free audit tool?
It should explain what it checked, show what to fix first, separate measured from guessed and never promise mentions.
- It explains what it checked. A bare score gives you nothing to act on.
- It ranks fixes.
- It separates measured from inferred.
- It does not promise mentions.
- It is clear about your data. Be wary of a “free” check that asks for card details.
A fictional Snapshot result
| Check | Result |
|---|---|
| AI readiness score | 62 / 100 |
| AI crawlers allowed | Yes |
| Business structured data | Missing |
| llms.txt file | Partial |
| Main blocker | No business schema |
The first fix would be adding LocalBusiness markup that matches the visible page.
This is a fictional sample to show the format, not a result for a real site.

What are the benefits of using AI for online visibility checks?
It is fast, repeatable, shows what customers see, reveals who is named instead of you and finds wrong information. See the benefits in detail.
Can a free tool tell me if ChatGPT recommends my business?
Not reliably on its own. A free scan shows whether your site is ready to be understood. Whether an assistant names you has to be tested by asking real customer questions.
No one controls what an AI assistant says. These steps improve your chances of being understood and recommended. They do not guarantee a mention, a citation or a position.
