Honestly, this is exactly why most tools claiming to track AI citations are basically guessing. Here's the breakdown.
First, there's the "segment of one" problem. Modern AI builds dynamic profiles that update in real time based on a user's browsing behaviour, scroll depth, even device type. That makes a single "rank" or "mention score" for a brand technically impossible to standardise. It's nothing like SEO where Google has a fixed database. Measuring AI visibility and Google rankings are worlds apart.
Second, the synthetic data issue. Tools like Semrush and Nightwatch rely on automated bots asking a fixed set of questions via API. Those bots don't carry a user's context, history, or professional background, so their "visibility scores" rarely match what real people actually see.
Finally, the transparency gap. OpenAI, Google, Anthropic and Perplexity do not provide analytics APIs for brand mentions. Until they do, any tool claiming to track mentions is using directional surveillance at best - simulations, not hard data.
If someone in the thread says their tool works, ask them to show you one real user's session. They can't, because the data simply isn't there yet.
