Six tools that make your website visible

Built for our own templates, left open to everyone. Each one answers a single question and gives you the result to keep.

  • 6 tools
  • €0 and no account
  • < 60 s per check

AEO Check

about 20 seconds

Does ChatGPT find an answer on my website?

We read your page the way a language model reads it and ask it the six questions every prospect asks before buying. You get two separate scores: whether a model can reach your content, and whether it finds an answer there.

  • Six visibility measurements, from robots.txt to the raw HTML
  • Six answerability questions, answered by the model from your text alone
  • For every gap a finished paragraph and the missing structured data block

AI Design Check

about 10 seconds

Does my website look like a website builder made it?

The check reads your source and looks for the marks you can spot stock design by from a distance: system fonts nobody chose, off-the-shelf gradients, default spacing, copy blocks that fit any industry.

  • Marks taken from the real source, not an opinion about taste
  • Every finding with the sentence a visitor actually notices
  • A comparison with a website built as a template
Open tool

AI watermark check

about 10 seconds

Which AI traces sit in this page?

The check reads a single page and its images and looks for what an AI leaves behind: invisible characters in the text, provenance data in the image files, traces of AI generators in the source, sentences out of a chat window. Every finding comes with the spot it sits in.

  • No guessing about writing style, only findings that can be shown
  • Reads the image files too, so C2PA, IPTC and the prompt inside a PNG
  • Also tells you whether the page discloses AI content
Open tool

llms.txt creator

about 30 seconds

How do I explain my website to a language model in one file?

llms.txt is a markdown file in your root directory that tells a model in a few lines what your website is about and which pages it should read. The creator reads your pages and writes it for you.

  • The creator reads your real subpages instead of guessing headlines
  • The file follows the structure that has settled in practice
  • You see where the file belongs and how to check that it arrives
Open tool

Invisible characters

instant

Does my text carry hidden marks from an AI?

Text from language models often carries characters you cannot see: narrow spaces, zero-width joiners, machine punctuation. Paste your text, see every character marked and download the clean version.

  • Runs entirely in your browser, your text never leaves the device
  • Every character found, with name, code point and position
  • One button that cleans everything without breaking your paragraphs

Website DNA

about 3 minutes

What does my AI need to know before it builds my website?

Nine questions, three minutes, one file. The Website DNA is the brief an AI can build a website from that sounds like you instead of like a template. You get it as a file in your inbox.

  • Nine questions that catch what separates your website from every other
  • The result is a file, not a report: you put it next to your project
  • Works with Claude, ChatGPT, Cursor and anything that reads files

  1. 1

    Measure first, judge later

    Start with the AEO Check. In twenty seconds it tells you whether a language model can reach your text at all. Everything else is wasted if that answer is no.

  2. 2

    Close the gaps it names

    The check hands you a finished paragraph for every gap. Put in the three that carry the most weight: offer, audience, difference. Then run it again and watch the number move.

  3. 3

    Give the AI a map

    The llms.txt creator writes the file that tells assistants which pages to read. Five minutes, and it works on every subpage.

  4. 4

    Look at how it looks

    The AI Design Check covers the other half, how your website hits a human being. Copy that convinces still loses to an interchangeable design.

  5. 5

    Look at what is inside

    The AI watermark check reads the same page once more, this time for traces rather than for effect. Invisible characters, where the images came from, sentences left behind. Ten seconds, three checks a day.

  6. 6

    Before the next text

    Text from an AI goes through Invisible characters once. And before the next page gets built, create your Website DNA so the AI knows what to sound like.

No. All six are free and work without an account. For the three that fetch an external website and query a language model, one check per day and device applies, because every query costs us real money. The AI watermark check needs no model and therefore allows three a day.

No. The address is used for the check and discarded afterwards. With the invisible characters your text never leaves the device in the first place, the check runs entirely in the browser.

No. Every tool works with any website, whatever it was built with. We built them because we needed them for our own templates, and left them open.

The AEO Check asks whether a language model understands your website and can quote it. The AI Design Check asks whether your website looks like stock to a human being. One is about the text, the other about the design, and the two are unrelated.

SEO gets you onto a result list, AEO gets you into an answer. Ask a question in ChatGPT or Perplexity today and you do not get ten blue links, you get a paragraph with two or three sources. Only text that carries a checkable statement makes it into that paragraph. That is a different job from ranking well, and it starts with the sentences on your page.

After every larger change to copy or structure, otherwise once a quarter. The findings only move when your page moves, a daily run tells you nothing new.

The tools show you what is missing. A template brings it along

Every finding these tools produce is already handled in our templates: an llms.txt ships with it, the six answers are in the copy, the structured data is set, and the design did not come out of a default. A finished industry website, knowledge and seven skills, €89 once.
