How it works
Three steps turn one prompt into a ranked fan-out list
The query fan-out tool needs a prompt, the engines to run it on and a market. We run the prompt on each engine, collect the sub-questions the engine generates while composing its answer, rank them by occurrence and email you the list. Online fan-out generators return a list on screen; this one sends the questions collected from the engines' answers.
-
Step 1
Enter your prompt
Paste the question your buyers ask, in their words. The sample uses a prompt about project management tools.
-
Step 2
Pick engines and market
Three engines are ticked by default. Pick the market, since answers vary by country and language.
-
Step 3
Get the list by email
Leave your work email and company. Our team sends the ranked fan-outs to that address.
Use cases
Fan-out lists feed 3 kinds of work, one per audience
The query fan-out tool gives each audience a list it can use the same week. Agencies turn the top questions into a content brief, platforms see which questions to add to a customer's prompt set, and brands find the sub-topics their pages do not cover yet. Each card opens the matching pattern.
Prompt ideas for every customer
Show customers the questions engines ask around their category and offer to track them. Each accepted question becomes a prompt in their set.
AgenciesA content brief from real questions
Turn the top fan-outs into H2s and FAQ entries, phrased the way the engine phrases them. The brief arrives with its evidence.
E-commerce & brandsSub-topics your pages miss
Compare the fan-outs of a product query with the questions your category pages answer. Every gap is a section to write.
Comparison
1 of 4 approaches gives you fan-out questions as a ranked list
The query fan-out tool runs on the same data as the Fan-Out API, which returns the follow-up questions with their occurrences. An AI scraping API returns the final answer without them, GEO dashboard tools rarely expose them, and an in-house build has to capture and count them for each engine.
| Capability | API for GEO | AI scraping API | GEO dashboard tool | In-house build |
|---|---|---|---|---|
| Fan-out follow-up questions | Yes | No | Rare | Build it |
| Raw answer text | Yes | Yes | Sometimes | Build it |
| Ongoing maintenance when engines change | Ours | Partly theirs | Theirs | Yours |
FAQ
Query fan-out tool, answered
How is the fan-out list produced?
The query fan-out tool runs your prompt on the engines you tick, records the sub-questions each engine generates while composing its answer, and ranks them by how often they appear. Our team then emails you the full list, which takes longer than an on-screen generator but reflects what the engines actually asked.
Why do fan-outs change with the market?
The query fan-out tool runs the prompt in the market you pick, because answers vary by country and language. A prompt asked in the United States and in France can expand into different sub-questions, so a brief for one market should start from that market's list.
How many fan-outs does one prompt produce?
The query fan-out tool's sample prompt produced 8 distinct fan-outs on ChatGPT, with about 4.7 per answer. Counts vary with the prompt and the engine, which is why the list is ranked by occurrence and the rare phrasings can be left out.
Can I get fan-outs for many prompts at once?
The query fan-out tool handles one prompt per request. For a whole prompt set, the Fan-Out API ranks the fan-outs across every prompt and response in scope, and reads them at no extra cost because they are captured during normal runs.
Is the sample result real data?
The query fan-out tool's sample uses a sample prompt and fictional brands, so it shows the shape of the list without describing a real market. Your own list comes from the prompt, engines and market you enter in the form.
