Tracked platforms
Every surface RankX AI watches, what each is good for, how RankX AI reaches it, and what widens it. Generated from the site's own platform list.
Every surface RankX AI watches, in one table. Five AI assistants plus Google AI Overviews, which is not an assistant and is measured a different way.
All of them are on every plan. There are no engine add-ons, by policy.
The surfaces
| Surface | Made by | What it is good for | How RankX AI reaches it | Widened by |
|---|---|---|---|---|
| ChatGPT | OpenAI | The one every reader recognises. Broadest coverage of everyday consumer and business questions. | Asked your tracked prompts, on the scheduled AI visibility run | Adding prompts |
| Claude | Anthropic | Nuanced research and document-heavy work. Strong in B2B, where the questions asked of it are longer and more specific. | Asked your tracked prompts, on the scheduled AI visibility run | Adding prompts |
| Gemini | Integrated with Google Search and Workspace, so it matters most to brands whose buyers already live in Google. | Asked your tracked prompts, on the scheduled AI visibility run | Adding prompts | |
| Grok | xAI | Live web and X access, so it picks up trending and real-time mentions the others miss. | Asked your tracked prompts, on the scheduled AI visibility run | Adding prompts |
| Perplexity | Perplexity AI | AI-native search with real-time citations, so it is the clearest view of which sources are surfaced beside you. | Asked your tracked prompts, on the scheduled AI visibility run | Adding prompts |
| Google AI Overviews | Not an assistant. A summary above a results page, captured by the rank tracker on tracked keywords. | Captured by the rank tracker, alongside the position check | Adding keywords |

The two columns that matter most
How RankX AI reaches it is the structural fact behind most questions about this data. The five assistants are asked your tracked prompts on the scheduled AI visibility run. Google AI Overviews is captured by the rank tracker on your tracked keywords, at the same moment as the position check.
Widened by follows from that. Adding prompts widens the assistant coverage and does nothing to your AI Overview data. Adding keywords widens the AI Overview data and does nothing to your assistant coverage. A Website with no tracked keywords has an empty AI Overviews section however many prompts it has.
Gemini and Google AI Overviews are both Google's, and still two things
The most common conflation, and it is understandable.
One is an assistant answering a tracked prompt in the scheduled run. The other is a summary above a results page, captured on tracked keywords. They use different sources, appear in different sections and move on different clocks, and a brand can do well on one and badly on the other.
Folding AI Overviews into the assistant list would also overstate your assistant coverage by a fifth, which is why the product keeps them apart.
What each surface costs
An AI visibility check is charged per prompt, per assistant, per run. So the five assistants multiply your prompt panel by five, and that multiplication is most of the recurring spend on almost every account.
An AI Overview capture is a speculative hold placed with the rank check and released in full when no overview rendered, so a tracked keyword settles at one of two prices on a given day.
Figures are on the credit cost reference.
Turning one off
An assistant can be disabled for a Website if it genuinely does not matter to your buyers. That removes it from every future run and from the cost of every run.
The trade: it stops the spend immediately, and it ends the series. A rate you stop collecting is a comparison you cannot make later, and the history you have does not extend itself.
Where to go next
- Tracked platforms, the guide rather than the table.
- Citations, two kinds, for the two citation surfaces these produce.
- Check cadence, for how often each is asked.
Plan limits
Every published RankX AI limit on both tracks, as one generated table, read from the same source the pricing page renders.
AI Readiness checks
Every check RankX AI's AI Readiness actually runs, with its category and its weight, generated from the product so it cannot list one that is not run.
