In a recent Show HN post dated September 21, 2026, developers from Kelriva introduced a free diagnostic tool designed to expose the verbatim responses generated by major Large Language Models (LLMs) regarding specific businesses. The tool queries ChatGPT, Claude, Gemini, and Perplexity in real-time, offering users a direct look at the narrative these models construct about their brand. This release addresses a growing concern in the marketing and tech sectors: the opacity of how generative AI synthesizes corporate identity from scattered web data.

Born From Blind Spots

The impetus for the tool’s creation was a sobering internal discovery. The Kelriva team reportedly found that their own company was effectively invisible to AI models when they tested an early version of the software on themselves. This realization highlighted a critical gap in traditional SEO strategies, which focus on search engine rankings but often neglect the specific context windows and knowledge cutoffs that LLMs utilize. The tool serves as a mirror, reflecting the sometimes hallucinated, sometimes sparse, and occasionally contradictory information that AI agents present to end-users.

Technical Scope and Methodology

While the source material is sparse on the underlying architecture, the tool’s function is straightforward: it executes live queries across four distinct model families to aggregate results. By including Perplexity alongside the big three proprietary models, the developers are acknowledging the diverse ecosystem of AI search interfaces. The team has explicitly offered to answer questions regarding their methodology, suggesting that the process involves more than simple API calls, potentially touching on prompt engineering techniques designed to elicit brand-specific summaries rather than general knowledge.

Key Takeaways

  • Kelriva's new tool provides real-time visibility into how ChatGPT, Claude, Gemini, and Perplexity describe a business.
  • The developers discovered their own brand was invisible to LLMs, exposing a blind spot in traditional SEO strategies.
  • The tool aggregates live queries across multiple model families to highlight inconsistencies in AI-generated brand narratives.

The Bottom Line

As LLMs become the primary interface for information retrieval, 'AI visibility' is rapidly replacing traditional SEO as a critical business metric. This tool is a necessary wake-up call for companies that assume their web presence translates directly to AI comprehension.
