Free Query Fan-Out Tool
AI search doesn't answer the question you typed with one search. It fans out into several. Enter a topic to see the likely sub-queries, grouped by intent, and find the ones you have no page for.
Sub-queries
Enter a topic to see the searches an AI engine is likely to run behind it.
What query fan-out is
Query fan-out is the step where an AI search system breaks a user's question into several related searches, runs them in parallel, and writes one answer from the combined results. Google describes AI Mode as using a query fan-out technique, and ChatGPT and Perplexity show the same pattern when they list the searches they ran.
The practical consequence: a prompt like "what's the best CRM for a small agency" may never match your page directly, but one of its sub-queries — "crm pricing for agencies", "hubspot alternatives" — might. Being the best source for those sub-queries is how you get into the final answer.
How to use the list
- Find gaps. Go group by group. If you have no page, section or FAQ that answers a sub-query well, that is a gap an AI engine will fill with someone else's content.
- Start with best-of and comparison. These are the sub-queries where engines name brands. Comparison pages and honest "alternatives" pages are often cited.
- Turn sub-queries into headings. An H2 that mirrors the question ("How much does X cost?") followed by a direct answer is easy to retrieve. Check your outline with the heading analyzer.
- Track the prompts, not just the keywords. Feed the strongest queries into the AI prompt generator or an AI visibility tracker to see which engines name you.
How the queries are generated
The tool uses templates built from common search patterns across ten intent groups, not a language model. That makes it instant, free and repeatable: the same input always produces the same list, so you can compare over time. The trade-off is that it won't invent niche angles specific to your market — treat the output as a starting map, then add the questions your sales team hears every week.
FAQ
Questions
Does every AI engine fan out queries the same way?+
No. Each engine decides how many searches to run and how to phrase them, and it varies by prompt. The intent groups here — best-of, comparison, alternatives, pricing, reviews and so on — are the ones that recur most, so covering them covers most fan-outs.
Why add a competitor?+
Comparison and alternatives sub-queries mention competitors by name. Those are high-intent searches where engines list brands side by side, so they're worth seeing explicitly.
Is this the same as keyword research?+
It overlaps, but the goal differs. Keyword research ranks terms by search volume. Fan-out mapping asks which supporting questions an answer needs, so you can make sure your site answers each of them.
