Which tool to use, and when.

Each tool answers one question. Start with the one closest to what you want to know today, and come back to the others as the picture fills in. None of them needs an account or a card, and there is nothing to install.

Use the AI Visibility Checker when the question is simply whether AI engines know you exist. It asks three questions across ChatGPT, Perplexity, Claude, Gemini and Google's AI results, reports which of them mention your domain, and checks whether your robots.txt file lets the AI crawlers in. It is the quickest first look at where you stand.

Use the AI Search Simulator when you have a particular keyword in mind. It puts that keyword to Google and four AI engines side by side, so you can see whether you rank on Google, whether Perplexity cites you from a live page, and whether ChatGPT, Claude and Gemini recall you from what they learned in training. It is the best of the six for spotting the gap between ranking and being named.

Use the AI Content Grader on a page you want AI engines to quote, such as a guide, a comparison or an FAQ. It scores the page on question headings, answer-sized paragraphs, schema, sources and structure using fixed rules, so you can change the page, grade it again and see exactly what moved.

Use the Schema Markup Generator when you need structured data and do not have a developer to hand. Fill in a form for one of eight common types, from LocalBusiness to FAQPage, and copy the JSON-LD into your page. It runs in your browser, so nothing you type is sent to us.

Use the llms.txt Generator to give AI crawlers a short, grouped map of your most important pages. It reads your sitemap, writes a description for each page and hands you two files to check and publish. It needs no email.

Use the ROI Calculator when the question is whether the work could pay for itself. It estimates a twelve-month return for SEO and for an AI agent from your own numbers, sets out its assumptions, and also runs entirely in your browser.

Three of the tools, the checker, the simulator and the grader, show headline results straight away and ask for an email before showing the full detail. If you add one, we email you your result with a link back to the tool, followed by a couple of follow-up emails you can unsubscribe from at any time. The other three never ask for an email.

The tools that fetch pages or ask AI engines have daily limits, because every check costs us something to run: three a day each for the checker and the simulator, five for the llms.txt generator, and ten pages a day for the grader, which calls no AI engine. The checker, the simulator and the llms.txt generator keep each result for a day, so repeating the same check that day shows the saved result rather than a fresh one, though it still counts towards your daily limit.

None of these tools is a full audit. Each one looks at a single slice: a handful of questions, one keyword, one page or one file. For the whole picture, the free audit puts a buyer question for your kind of business to ChatGPT, Perplexity and Google's AI Overviews, shows whether each one names you or a local competitor, and sums up where you stand in one AI Visibility Score, with the areas of your site holding it back rated alongside.

And when you would rather someone did the work than measured it, that is what we do: the agent proposes fixes, a person approves every change, copy changes come to you first, and the changes go live on your website, checked on the live page after they ship, with every change logged where you can see it.

Why free?

We built these tools because the first step of every client engagement is the same: find out where you stand. If we can give that step away for free, the businesses who need our help will see it clearly, and the ones who do not will learn something useful. Everyone wins.

There is no trial period and no "premium unlock". Three tools ask for an email before showing the full findings. If you add one, we email you your result with a link back to the tool, followed by a couple of follow-up emails you can unsubscribe from at any time. The tools are free, and we have no plans to change that.

Want the full picture?Run the audit.

The free audit tells you whether ChatGPT, Google’s AI Overviews and Perplexity name you when a buyer asks, which competitors they name instead, and why they pass you over, all summed up in one score out of 100. Sixty seconds. No card.
