What it does

AI doesn’t search what you typed.

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.

How it works

Three clicks, start to finish.

1

Install RankOS Fan-out

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.

2

Ask anything on ChatGPT, Perplexity or Gemini

Ask a question that needs live info — a comparison, a “best X for Y”, a how-to. The AI answers exactly as normal.

3

Hit Fan-out

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.

What you see

Everything the AI did to answer you.

The exact sub-queries

The real searches the AI ran, not your original question — each one a piece of content you could write to get found.

Search vs site:

See when the AI ran a live web search versus hunting inside one specific website. Different intent, different play.

The sources it cited

The pages it pulled facts from to build the answer. That's who you're up against to get cited.

The chain of thought

Where the model exposes it, see how it reasoned before it answered — in plain English.

Private by design

No ads. No cross-site tracking. No remote code. It reads only the current answer, nothing else on the page.

Send to RankOS

Push the queries you like into RankOS and turn them into content built to be the answer AI gives.

Why it matters

The fan-out is your content map.

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.

Questions

RankOS Fan-out, answered.

What is RankOS Fan-out?

RankOS Fan-out is a free Chrome extension that reveals the query fan-out behind an AI answer — the hidden sub-searches ChatGPT, Perplexity and Gemini run before they reply.

What is a query fan-out?

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.

Is RankOS Fan-out safe? What data does it collect?

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.
