Query fan-out
See the hidden searches behind one AI prompt
One user prompt becomes many internal retrievals. This generator shows the branches each major AI surface is likely to run — so you can plan content that wins the branches that matter.
Frequently asked questions
- What is query fan-out?
- When you hand a modern AI search surface a long prompt, the system quietly splits it into several narrower sub-queries and retrieves sources for each before writing one reply. The branches you win — not the original keyword — decide whether you are cited.
- Why does the tool output heuristic branches instead of real ones?
- Each vendor's exact decomposition is proprietary and non-deterministic. This tool mirrors the public descriptions from Google, OpenAI, and Perplexity to produce plausible branches that match typical retrieval behavior, with intent labels you can map to content.
- How do I turn this into a content plan?
- Pick the branches you care most about, then check whether a single page on your site already leads with the answer for each one. Gaps become spoke pages; weak answers get rewritten answer-first.
- Can I try different engines on the same prompt?
- Yes. Switch the engine selector — ChatGPT tends to add year modifiers and buyers' guide branches, Google AI Mode leans toward entity and statistics branches, and Perplexity favors research and how-to branches.
