Real user experience, not raw API responses

We connect directly to the consumer-facing UI of each AI search engine, adjusting geography and locale so the brand mentions match what your customer actually sees. Many APIs query provider backends directly, where the output differs from what end users get.

Statistically reliable mentions through replicates

LLMs are non-deterministic. We execute multiple searches per prompt and aggregate the results, so brand mention rate, average position, and coverage reflect real statistical patterns, not single-shot noise.

Cited sources behind every brand mention

AI engines lean on internal web searches to ground their answers. We extract and analyze the sources cited for each prompt, so you can see which articles, reviews, and domains drive the brand mentions you track and build a concrete GEO strategy.
