No single free tool audits AI visibility end to end. The best free setup combines a website readiness scan, the free versions of the AI assistants for prompt testing, Bing Webmaster Tools for citation data, Search Console, a structured data validator and a spreadsheet. Together they take about 30 minutes to run.
Prompt test: asking an AI assistant a realistic customer question in a new chat and recording whether it names your business, links your site and who it names instead.
Which free tools are worth using?
Six free tools cover the technical check, the assistants’ answers, Microsoft’s citation data, indexing, markup and tracking.
| Tool | Question it answers | Limits |
|---|---|---|
| Website readiness scan (the free CoreTxt Snapshot) | Can AI systems read and understand my site? | Does not query the assistants |
| Free ChatGPT, Gemini, Perplexity and Claude | Does an assistant name my business? | Answers vary; repeat each question |
| Bing Webmaster Tools AI Performance (beta) | Is Microsoft’s AI citing my pages? | Microsoft only; no clicks or competitors |
| Google Search Console | Is my site indexed and found? | No report on whether ChatGPT names you |
| Rich Results Test and Schema Markup Validator | Is my business markup valid? | Checks markup, not visibility |
| A plain spreadsheet | Am I improving? | You maintain it |
What to do next: Run the free Snapshot first for a baseline.
How do you test the assistants well?
Use customer wording, a new chat for each question and more than one run.
Perplexity shows its sources with every answer, which makes it handy for seeing which sites an assistant leans on in your market.
What to do next: Follow how to test if AI recommends your business.
What does Bing’s AI Performance report add?
It shows how often your site is cited in Copilot and Bing AI answers, which pages are cited and the phrases the AI searched for.
It is in beta at the time of writing, covers Microsoft’s AI only and does not show clicks or competitors. The phrases it lists are a good source of questions to test in the other assistants.
What does a 30-minute free audit look like?
Run the scan, test ten questions, check Bing and Search Console, then validate your markup.
- 5 minutes: run the free Snapshot and note the main blocker.
- 15 minutes: ask ten customer questions in two or three assistants and record the results.
- 5 minutes: check Bing Webmaster Tools and Search Console.
- 5 minutes: validate structured data on your home page and top service page.
A fictional 30-minute audit log
| Step | Finding |
|---|---|
| Snapshot | 62 / 100, main blocker: no business schema |
| Ten questions, three assistants | Named in 4 of 30 answers (13%) |
| Bing Webmaster Tools | No citations yet |
| Markup validator | Organization markup valid; LocalBusiness missing |
Fix the main blocker, then repeat the same ten questions in a month.
This is a fictional example to show the format. It is not a CoreTxt test result and not data about a real business.
What will free tools not do?
They will not explain why a competitor is chosen, run hundreds of questions or build a prioritized plan.
