These tools find the questions users ask ChatGPT and Perplexity

by Johannes Zimmer · · 4 min read · GEO
In short

Two tool categories find the questions users ask AI assistants: AEO tools (Answer Engine Optimization), which query ChatGPT, Perplexity and co. with your audience's prompts and log what comes back, and tools that scan a domain or brand name and automatically derive possible questions from it. One category starts from the question, the other starts from your website.

TL;DR
  • Two categories: AEO tools query AI assistants with prompts and log the answers; other tools derive questions automatically from a domain or brand name.
  • Three technical routes behind them: direct prompt analysis, automated reverse engineering, and techniques like RAG.
  • Unlike keyword research, question scouting doesn't count terms; it captures real questions the way they are asked in chat interfaces.

Which two tool categories actually help?

There are two categories that really help here. First, AEO tools (Answer Engine Optimization), which deliberately query AI assistants with your audience's prompts and log what comes back: which sources get cited, which entities the answer links to your topic, how the answer is structured. Second, tools that generate search queries automatically by scanning a domain or brand name and deriving possible questions from it. Both categories solve the same problem from two directions: one starts from the question and watches what the AI makes of it, the other starts from your website and derives the question.

How do these tools get at the questions?

Technically this runs along three routes that often complement each other. The first is direct prompt analysis: entering the same phrasings real users would type and systematically evaluating what the assistant answers, which sources it names and how it structures the answer. That delivers first-hand information, with no detour through an index. The second route is automated reverse engineering: a tool scans a domain or company name and independently generates plausible search queries from it, without anyone having to phrase the questions by hand. The third route comes from the technology behind the answer engines themselves. Techniques like Retrieval-Augmented Generation, RAG for short, pull in additional external data when answering, to ground answers more precisely and more broadly.

Why does question scouting work differently from classic keyword research?

Classic keyword research asks: what does someone search for, and how often per month? Classic SEO tools provide functions for researching relevant terms and phrases along with their monthly search volume. The problem: whoever types into ChatGPT or Perplexity isn't searching for terms, but asking questions, the way you would ask another person. Question scouting starts exactly here: identifying and capturing real user questions the way they are asked in chat interfaces, instead of counting individual terms.

How do you use the questions you find for your website?

The questions you find become a work queue: check each question against your own website (which ones does it already answer, which not?) and close the gaps with answer-ready articles. That is exactly the loop flize bundles: scouting, answer check and content production, for your own domain or for clients. How to then measure whether the answers cite you: How do I measure my visibility in AI answers?

FAQ

Where do these tools hit their limits?

+

One limit concerns not the tools themselves but what comes out at the end. If you work with Perplexity or use Perplexity answers as a reference for your own research, you do get source citations and save time, but that doesn't protect you from errors. Users should still check the delivered information for accuracy, because here, as with all AI tools, there is a certain susceptibility to wrong or imprecise statements.

How do I choose the right tool for my use case?

+

The choice depends on how structured you want to work. There is a step-by-step framework for finding suitable prompts in the first place, filtering them and selecting them for ongoing tracking, instead of collecting questions at random.
