Not identically, and we won't claim they do. We call each provider's API directly and record the real response. But the consumer apps — ChatGPT, Claude.ai, Gemini — often have live web search switched on, while several of our probes measure what the model has learned about your business from its training. Those can differ.
We made that choice deliberately: API probes are consistent and repeatable, which is what you need to track a trend. A consumer app that live-searches every time is a moving target. Perplexity is the exception — it's search-based, so it most closely mirrors the consumer experience.
The honest framing: we give you a stable benchmark, not a screenshot of what one specific customer sees on one specific day.
