1 Classifier

Decides whether to use web search. The classifier analyzes your query and determines if real-time web data is needed to provide an accurate answer.

2 Thinky

Plans the search strategy. If web search is needed, this stage formulates the optimal search queries to gather the most relevant information.

3 Search

Actively searches the web and extracts results. ChatGPT sends search queries and receives a list of relevant web pages and snippets.

4 Fetch

Reads specific web pages for detailed information. ChatGPT visits individual URLs to extract full content from the most promising search results.

5 Synthesis

Generates the final answer from gathered data. All collected information is combined and synthesized into a coherent, comprehensive response.

6 Streaming

Transmits the response to you. The final answer is streamed token by token to your browser, appearing as the familiar typing effect in ChatGPT.

Source Transparency

The GPT Request Monitor captures and displays every domain and full URL that ChatGPT accesses during its response generation:

• See exactly which domains ChatGPT uses as sources for its answers
• View the full URLs of every web page ChatGPT reads
• Understand which websites influence AI responses about your brand
• Track how often specific domains appear across different queries
• Identify authoritative sources that ChatGPT relies on in your industry

Why Brand Managers Need This Extension

The GPT Request Monitor is an essential tool for anyone managing a brand's presence in AI-generated responses:

• Understand why ChatGPT recommends (or doesn't recommend) your brand by seeing which sources it consults
• Identify competitor sources being cited — discover which competitor websites ChatGPT reads when answering queries in your industry
• Discover content gaps — if ChatGPT never fetches your website, your content may not be optimized for AI discovery
• Validate AI responses — cross-reference ChatGPT's cited sources with the actual information on those pages
• Monitor changes over time — track whether ChatGPT starts or stops using specific sources for brand-related queries

Getting the Most Out of GPT Request Monitor

• Use the GPT Request Monitor alongside the AI Visibility Tool for comprehensive monitoring — the extension shows real-time pipeline data, while the AI Visibility Tool tracks long-term trends across multiple AI platforms.
• Test different query phrasings to see how ChatGPT's source selection changes based on how questions are asked.
• Pay attention to the Fetch stage — the URLs accessed here are the most influential sources for the final answer.
• Compare results with and without web search to understand when ChatGPT relies on its training data versus live web content.
• Use the domain information to prioritize your SEO and content strategy for the websites ChatGPT frequently consults.
