ChatGPT Search Inspector: How We Peek Behind the AI Curtain

June 29, 2025 · 4 min read

Have you ever wondered how ChatGPT finds answers when you ask it a question? Does it just know everything, or does it actually search the web?

Here at Spotlight, our research team is obsessed with figuring out how AI tools like ChatGPT talk about brands. To help us understand what's going on under the hood, we built a simple (but powerful!) Chrome extension called ChatGPT Search Inspector.

It’s a tool we use every day—and now we’re making it available to everyone.

Why Does ChatGPT Search the Web?

First, let’s get one thing clear: ChatGPT doesn’t always search the internet. In fact, about 50% of the time, it gives answers from what it already knows from its training dataset.

But when thinks it needs fresh data, it searches the web (Bing and/or Google) in real time.

Here’s when ChatGPT might search the web:

  • To find up-to-date information (like current events, prices, or sports scores)
  • To discover product listings or comparisons
  • To check what’s trending or popular online
  • To look up specific websites or recent articles
  • When it needs more details it doesn't already know

When it does this, ChatGPT sends a query to a search engine (usually Bing). Then, it looks through the top results, picks the ones that seem helpful, and uses them to build a response.


What Does the ChatGPT Search Inspector Do?

ChatGPT Search Inspector lets you see exactly what ChatGPT is searching and what links it’s reading. Think of it like holding a magnifying glass up to ChatGPT’s brain while it works.

Here’s what the tool shows you:

  • Search queries ChatGPT sends to Bing
  • Web pages ChatGPT actually visits
  • Summaries of those pages (what info ChatGPT pulls out)
  • Timing of when each page was opened

All this data appears in real time, while ChatGPT is browsing—right in your browser window.


Why This Matters for Brands

If you work in marketing, SEO, content, or brand strategy, this tool can give you superpowers. It shows which websites ChatGPT trusts, and what kind of content it uses in answers.

That’s a huge deal. Why?

Because when someone asks ChatGPT about your brand—or your competitor’s—it pulls from what it knows and what it finds. And what it finds depends on:

  • The search query it uses
  • The websites that show up in results
  • The content on those pages

If your brand shows up often in those results? You’re in a good spot.
If not? You might be invisible to AI.


How Brands Can Use This

By using ChatGPT Search Inspector, you can:

  • See what ChatGPT sees when it searches your space
  • Understand why your competitors show up more than you
  • Improve your content to match what ChatGPT prefers
  • Increase your chances of being mentioned or recommended
