actually search.
Behind every answer is a chain of micro-searches the model runs against the open web. Centium captures every branch so you can see what it’s looking at, not just what it ends up saying.
one prompt becomes many searches.
When AI models receive a prompt, they break it down into micro-searches.
Centium reports the entire chain of searches from ChatGPT and Gemini, giving you insight into the exact search process behind every answer. It’s the data foundation for AEO (Answer Engine Optimization) and GEO (Generative Engine Optimization).
Every branch is an opportunity. To rank, to be cited, to influence the answer. Or to be invisible.

you're optimizing the tip of an iceberg.
Centium reveals how AI models actually probe a topic, just like a human would. Reviews, rankings, news, competitor comparisons, fit and use-case questions, all the angles the model considers before it answers.
Each branch is a content opportunity, an SEO, AEO, and GEO opportunity, a chance to be the source the model cites.

not just what it searched, but why.
A raw search is a clue. Centium reads the intent behind every micro-search and sorts it into a theme, so you see not only what AI looked for, but the reason it looked, the angle you have to cover to be found.
It reports two ways: the share of prompts that trigger a theme, and the share of every search it makes up. When ranking and recency run high, AI is hunting current best-of lists, so that is what you publish.
