Ten free tools for SEO, answer engine optimisation and generative engine optimisation. Each one checks a single thing that affects whether search engines and AI assistants can read, understand and quote your website. No sign-up, no email address, no limits on use.
We built these because the checks we run at the start of every client engagement are mostly mechanical, and there is no reason to charge for them. Seven of the tools run entirely in your browser, so nothing you paste leaves your computer. Three need to read one public file from the site you enter, such as robots.txt or a sitemap, and store nothing.
All ten tools

|---|---|---|
| AI Crawler Access Checker | Which of 19 AI and search crawlers your robots.txt allows, and whether your server actually answers them | A domain |
| Content Chunking Analyser | Which passages on a page still make sense when quoted alone | Page text or HTML |
| NAP Consistency Checker | Where your business name, address and phone differ across listings | Your listing details |
| Organization Schema Builder | Ready to paste JSON-LD that ties your website to your other profiles | Business details |
| Table and Data Density Scorer | Whether your facts and figures are marked up so a machine can extract them | Page HTML |
| Sitemap Freshness Auditor | How old your pages are by lastmod, and whether your lastmod can be trusted | A sitemap URL |
| AI Visibility Prompt Generator | A set of buyer questions to test in ChatGPT, Gemini and Perplexity, with a tracking sheet | What you sell and where |
| IndexNow Key and Payload Helper | A key, a verified key file and the exact request to tell Bing a page changed | A domain and URLs |
| Hreflang Tag Builder | Correct, reciprocal hreflang tags for every language version of a page | Language codes and URLs |
| FAQ Schema Generator | FAQPage JSON-LD from a plain list of questions and answers | Questions and answers |
Which tool to start with
The order matters, because each layer depends on the one below it. A well written page does nothing if crawlers cannot reach it.
1. Can crawlers reach you?
Start with the AI Crawler Access Checker. It reads your robots.txt against 19 crawlers, including GPTBot, ClaudeBot, PerplexityBot and Googlebot, and then requests your page the way a crawler would. That second step catches the common case where robots.txt says yes but a firewall says no, or where the page is empty until JavaScript runs. Then use the Sitemap Freshness Auditor to see whether your sitemap is telling crawlers the truth about what has changed, and the IndexNow helper to notify Bing directly when it has.
2. Do machines know who you are?
The Organization Schema Builder produces the block of structured data that connects your website to your LinkedIn page, your directory listings and your founders. The NAP Consistency Checker finds the small differences in name, address and phone across listings that make one business look like several. It understands Indian address conventions, so “Plot No. 14, MIDC Ph 2” and “Plot 14, M.I.D.C. Phase II” are treated as the same place.
3. Is your content built to be quoted?
The Content Chunking Analyser splits a page into passages and flags the ones that lean on the paragraph before them. The Table and Data Density Scorer checks whether your specifications and prices sit in real tables and lists, or in images and styled boxes that a crawler cannot read. The FAQ Schema Generator and Hreflang Tag Builder handle two pieces of markup that are easy to get subtly wrong.
4. Is any of it working?
The AI Visibility Prompt Generator gives you a consistent set of buyer questions to run through each assistant every month, and a sheet to record whether you were named and which sources were cited. This is the only honest way to measure AI visibility, and it costs nothing but time.
What these tools do not do
None of them predicts what an AI assistant will cite. Nobody outside the companies that build the assistants can see how sources are chosen, and any tool that gives you a “citation probability” is guessing. These tools check things that are observable: whether a file is reachable, whether markup is valid, whether a passage reads as complete. Getting those right removes the reasons you might be skipped. It does not guarantee you will be chosen.
They also do not replace judgement. A page can pass every check here and still say nothing that anyone needs. For the thinking behind each check, the AI Search Academy explains the mechanics in plain language.
Frequently asked questions
Are the tools really free?
Yes. There is no account, no trial period and no usage cap beyond a rate limit that stops automated abuse of the three tools that fetch remote files.
What happens to what I paste in?
For seven of the ten tools, nothing. The processing happens in your browser and the text never reaches our server. The crawler checker, the freshness auditor and the IndexNow verifier ask our server to fetch one public file from the domain you enter. The tool does not save the domain or the result. Like any website, our server keeps standard access logs.
Do I need to be technical to use them?
No, but some outputs need someone who can edit your website to apply them. Each tool page says exactly where the output goes.
Can you just do this for us?
Yes. These checks are the first day of an AI Search Audit. The audit goes further, into what your competitors are cited for and what to publish next. If you would rather hand it over, get in touch.
