Run a query through ChatGPT's API and through what real users see in the ChatGPT UI. See how the brand mentions, citations, and rankings differ. Most teams optimize for the API answer. Their customers see the UI answer. The gap between them is your blind spot.
Same prompt. Same brand. Different answers depending on where you ask.
The API returns a clean answer with structured sources. The UI cites a different set of URLs because the UI is doing live web search; the API is reading from training cutoff plus tool-use traces. Your blog post may rank in one and vanish from the other.
"Best CRM for startups" surfaces Notion in the API answer at rank 3 and the UI answer at rank 7. Same model, same query. The difference is the UI's grounding model and the API's RAG path. Both are real customer experiences. You need to track both.
The UI quietly expands a prompt into 3-7 sub-queries before answering. The API doesn't show you those sub-queries. That fan-out is where most of your SEO investment has to land. If you can't see it, you can't optimize for it.
Built on /v1/check mode=deep. The same primitive every paying customer uses.
ChatGPT, Claude, Gemini, Perplexity — straight from their official APIs. This is the answer your code sees today.
Live UI scrapes via our dedicated browser-based scraping infrastructure. Five runs lets us bound the variance — the same UI answer can shift across runs even at temperature zero.
Wilson 95% confidence on mention rate, bootstrap CI on rank distributions. Numbers come with error bars or they don't ship.
Brand mentions on each side, missing citations, fan-out sub-queries the API never surfaced, rank movement across runs.
The API-vs-UI delta is the single most counterintuitive measurement in AI-search optimization. It's also the one that decides whether your investment in content actually shows up where customers see it. Running this once on your own brand answers the question better than any sales pitch we could write.
If the delta is small, you don't need us. If the delta is big, you do. Either way you saved a meeting.
