# AI visibility tools: who ChatGPT and Perplexity cite for your queries

> An AI visibility tool asks the engines directly instead of reading Google's results. What an AI-citation tracker measures, how it differs from a rank tracker, and how the free pre-check keeps the paid probes on winnable queries.

An **AI visibility tool** measures whether AI engines cite your site, not where it ranks — because Google positions don't tell you whether **ChatGPT** or **Perplexity** quote you. We built a probe that **asks the AI engines directly** for your tracked queries, reads their answers, and shows: [are you cited](/ai-visibility/), and **who is cited instead of you**.

## The problem: the tracker sees results, not the AI answer

A classic rank tracker knows one thing — a link's position in the SERP. From it you can *indirectly* [guess a Google AI Overview hit](/tools/ai-overview-checker/). But engines that aren't built on Google's results — **Perplexity, ChatGPT Search** — are invisible to a normal tracker. And that's increasingly where whether a person sees your brand gets decided.

## What we built

`/seo-matrix:ai-citation` takes the same set of tracked keywords and, for each, **actually asks an AI engine** (Perplexity `sonar` by default; provider-agnostic), then parses the answer:

- **whether you're cited** for that query;
- **which domains are cited instead of you** (competitors in the answer);
- **citation share** — your share of citations across the query set;
- **movement vs the last run** — who entered the AI answers, who dropped out.

History is journaled (`ai-citation-history.jsonl`), so you see the trend, not a single snapshot.

> **Validated live** — The parser is validated against the real Perplexity API: the response returns sources in `citations` (a URL list) ∪ `search_results[].url`, plus text in `choices[].message.content`. The probe reads both — and is robust to either being empty.

## First — a free pre-check

The probe is paid: one call per keyword. To avoid spending on queries you can't win, there's a **$0 offline pre-check**, `/seo-matrix:citation-sim`. It takes the best page for each keyword, scores its **citation-worthiness** (the same 0–100 heuristic as citation-audit), and predicts a verdict — *likely / borderline / unlikely / weak / no_coverage* — splitting queries into "🔬 probe" vs "🛠 fix first." The paid probe spends only on what's actually winnable.

## Why it works this way

An AI answer is assembled from extractable passages, not positions: one query fans out into sub-queries, and a source makes the answer by citation frequency, not by its rank line (see our breakdown, [What is GEO](/blog/what-is-geo/)). So "am I cited" is a **separate metric** — measure it with a direct probe, don't infer it from positions.

## What to do with it

1. Run `citation-sim` → get the list of winnable queries.
2. Run `ai-citation` on them → see where you are, where a competitor is.
3. Where a competitor is cited, strengthen the page (facts, sources, extractable paragraphs) and re-probe.

## In short

- Positions ≠ AI citation; a normal tracker can't see Perplexity/ChatGPT.
- `ai-citation` asks the engines directly → are you cited, and who instead of you.
- `citation-sim` ($0) filters out unwinnable queries first — pay only for winnable ones.
- Citation is a separate metric; measure it with a direct probe.

## FAQ

### How is an AI-citation probe different from a rank tracker?

A tracker shows a link's position in Google. The probe directly asks an AI engine (Perplexity, ChatGPT) your queries and parses the cited sources — so it sees whether you're cited and who's cited instead, across engines the SERP can't show.

### Is it paid?

The probe itself is — one API call per query. But there's a $0 pre-check first: it scores each page's citation-worthiness offline and tells you which queries are even worth probing.

### Which engines are supported?

Perplexity (sonar) by default, with a provider-agnostic design. Google AI Overview citation is additionally read from the SERP itself.
