See the query fan-out behind any AI answer — the hidden sub-searches ChatGPT, Perplexity and Gemini actually run before they reply. Free, private, one click.
It rewrites your question into a fan-out of sub-searches, runs them all, and writes its answer from what it finds. Those sub-searches are the exact questions you need to answer to get cited. RankOS Fan-out shows you every one — on the answer, as it happens.
Add it to Chrome free, pin it to your toolbar, and enter your email once to unlock it. It sits quietly until you need it.
Ask a question that needs live info — a comparison, a “best X for Y”, a how-to. The AI answers exactly as normal.
See every sub-search the AI actually ran, whether each was a live search or a site: probe, and the sources it read. Send the ones worth writing for straight to RankOS.
The real searches the AI ran, not your original question — each one a piece of content you could write to get found.
See when the AI ran a live web search versus hunting inside one specific website. Different intent, different play.
The pages it pulled facts from to build the answer. That's who you're up against to get cited.
Where the model exposes it, see how it reasoned before it answered — in plain English.
No ads. No cross-site tracking. No remote code. It reads only the current answer, nothing else on the page.
Push the queries you like into RankOS and turn them into content built to be the answer AI gives.
Ranking on Google matters less; being the answer AI gives matters more. Every sub-search the model runs is a question your next article could own. See them, write the piece those searches are looking for, and you become the source the AI quotes next time.

ChatGPT, Perplexity and Gemini today, with more engines on the way. Open any of them, ask a question that needs live info, and hit the Fan-out button on the answer.
When you ask an AI a question, it doesn't search your exact words. It rewrites your question into a set of sub-searches — the fan-out — runs them all, and assembles its answer from what it finds. Those sub-searches are the exact questions you need to answer to get cited by AI, and RankOS Fan-out surfaces every one.
It reads only the current AI answer's own data to pull out the queries — never your other tabs, your browsing history or your keystrokes. It loads no remote code, shows no ads, and does no cross-site tracking. The only thing it collects is the email you enter to unlock it. Full details are in the privacy policy at getrankos.com/privacy.
Add RankOS Fan-out from the Chrome Web Store, pin it to your toolbar, and enter your email to unlock it. Then open ChatGPT, Perplexity or Gemini, ask a question, and click Fan-out on the answer to see every search the AI ran.
Free to install. See the searches behind every AI answer and turn them into content that gets cited.
