AI CitationBase · source-verified answers for AI and humans

Get cited in AI answers

AI cites what it can retrieve and verify. Humans decide the same way. So here is the data — every number links to its receipt.

Questions buyers ask us

Can you guarantee my brand gets cited by ChatGPT or Perplexity?

No — and nobody honestly can. Citations are never sold or promised here. What we do: publish your verifiable data in a form AI engines can retrieve and attribute, then measure whether and where it appears. Measurement shows movement; it is not placement.

What exactly do I get for $199?

One published benchmark: you submit the number, period, scope, and evidence; an editor verifies it; it goes live at /facts/{brand}/{slug}/, permanently labeled brand-official submission, in the same machine-readable formats (llms-full.txt, answers.json) as the rest of the corpus, and included in the monthly measurement. One-time fee — the page stays up.

How does the monitoring work?

A fixed prompt set (the questions buyers actually ask in your category) is run monthly against 7 AI engines, on record with engine and date. You get a citation-share table, a brand-accuracy audit, and a retrieval gap list. $99/mo for one brand domain, $299/mo for agencies with 5 client domains.

Is the editorial corpus really free?

Yes. Every independently verified answer on /qa/*, the full machine formats, the search API, and both free tools (llms.txt checker, AI crawler checker) are free, registration-free, and CC-BY-4.0 with attribution.

How is this different from a GEO agency?

We publish primary data and measure citations — we don't sell placement, run link farms, or promise rankings. If you want presence in AI answers, the honest lever is verifiable data that engines can cite with attribution.
