Halfanvil AI Footprint
Your customers ask AI assistants who to buy from. Find out if they hear your name.
We ask ChatGPT, Claude and Perplexity the questions your buyers ask, with web search on, several times a week, spread over the month. You see how often your business is named, which pages the assistants read to answer, and which of those pages you can get onto.
Free first report when it opens. Then 7 EUR a month, or 4 EUR for the first 50 founding seats. Prices without VAT, added at checkout where it applies.
Example. Made-up business, made-up numbers.

How it works
-
Tell us your site and your buyers' questions.
Your website and up to 10 questions people ask before they buy, such as "best wedding cake bakery in Lisbon". We suggest questions from your site; you change them.
-
We ask each assistant, again and again.
Every question goes to ChatGPT, Claude and Perplexity with web search on, several times a week, spread over the month. Answers change from one run to the next, so one try tells you little; many tries show a pattern.
-
You get counts, sources and one next step.
Named in N of M answers, the pages the assistants read most, whether you are on each, and one plain action per page. One report by email each month, and a short alert only when something material changes.
No script to install on your site. No calls. Nobody works on your account by hand; the same rules run for every customer.

What the assistants say about you
"Open on Sundays" source: an old directory page. Your site says: closed on Sundays.
Action: correct the directory listing.
- Counts, never a score. You see the numbers we measured, out of how many tries.
- Traced to the source page. If an assistant states a fact about you, we show the page it came from.
- Drafts are marked as drafts. Where an action needs text (a listing, a profile), the paid report includes a draft you edit before using.
Who it is for
For you if:
- you run a small service business, a shop or an app, and people find you by asking what to buy;
- you want to know what ChatGPT, Claude and Perplexity say about you, without paying for an enterprise tool;
- you have an hour a month to act on a short list.
Not for you if:
- you track dozens of brands for clients and need daily data and exports (agencies are better served by the bigger tools);
- you want someone to do the work for you, or a promise that you will be named. Nobody can promise that.

Free first report
When AI Footprint opens, you can run one report for your business for free and watch it fill in: 10 questions, each asked of ChatGPT, Claude and Perplexity, with the mentions and the pages they read shown in full. The actions and drafts are the paid part. One free report per website.
The free report is not live yet. The waitlist hears first.
FAQ
Do you guarantee I will be mentioned?
No. Nobody controls what these assistants say. We measure what they say and show the pages they read. What you do with that is up to you.
What counts as a mention?
Your business is named in the answer text, by name or by your website address. A link in a footnote without your name in the answer is listed as a source, not counted as a mention.
Which assistants do you check?
ChatGPT, Claude and Perplexity, each with web search switched on, the way most people use them. Answers without web search are often months out of date, so we do not use them. If we add an assistant, the report says so.
Why counts and not a score?
A score hides how little it is based on. "Named in 3 of 8 answers" tells you what we saw and how many tries it came from. Answers vary from run to run, which is why each question is asked several times a week, spread over the month.
Why not every day?
For a small business, the pages the assistants read change over weeks, not hours. Weekly data and a monthly report keep the price low. You get an alert if something material changes, such as a new page in the top five or your first mention.
What is in the free first report?
Your 10 questions, each asked of ChatGPT, Claude and Perplexity, with the mentions and the pages they read. Actions and drafts come with the paid report.
Are the prices with VAT?
Prices without VAT, added at checkout where it applies.
What happens to my waitlist answers?
We read them to decide what AI Footprint covers first, and we use your website and question to prepare your free report. Nothing is sold or shared. Deleted on request.
Do I need to install anything?
No. We look at your site from the outside, the way the assistants' crawlers do. If you want to see visits that come from AI assistants, Microsoft Clarity or Google Analytics show that for free.
How do I cancel?
From the Manage subscription link at the bottom of every page. Log in with the email you paid with and cancel. You keep access until the end of the paid month.
