ClayHog is a Generative Engine Optimization (GEO) analytics platform that tracks how your brand and competitors appear in responses from AI chatbots — ChatGPT, Gemini, Perplexity, Claude, and Google AI Overviews. It monitors mention frequency, sentiment, share of voice, and ranking position across AI surfaces, giving marketers a unified view of their AI visibility. The platform runs automated queries across AI platforms on a scheduled basis, tracking how mentions change in response to your content and PR activity. It surfaces which competitors are being recommended over you, what attributes each AI associates with your brand, and which of your keywords appear in AI-generated answers. A competitive intelligence dashboard lets teams benchmark their AI presence against up to 10 competitors. GEO as a practice is emerging rapidly as AI chatbots increasingly intercept search traffic — ClayHog is one of the first dedicated platforms in this space. The product launched on Product Hunt in April 2026 and attracted 146 upvotes, with particular interest from SEO agencies adapting to AI-first search. Pricing is tiered, with plans for solo founders, agencies, and enterprises.

Rival.tips is a research tool and interactive visualization that fingerprints the stylistic DNA of 178 AI language models — measuring vocabulary patterns, sentence structure preferences, hedging language frequency, formality registers, and punctuation habits — then clusters them into a navigable map showing which models write like which. The result is a kind of "accent atlas" for AI: you can see at a glance that GPT-4o and Claude Sonnet cluster together on formality but diverge sharply on hedging language, while Llama-3 and Mistral write more similarly to each other than either does to any OpenAI or Anthropic model. The tool works by running a standardized suite of 40 prompts across all 178 models, extracting 120 stylometric features per response, and reducing the high-dimensional space to an interactive 2D UMAP projection. The Show HN post hit 68 points with discussion focusing on the methodological choices and surprising cluster assignments — several models that market themselves as distinct turned out to be nearly indistinguishable stylistically. Practical applications include AI content detection research, model selection for brand voice matching, and detecting when a provider has silently updated their model (stylometric drift is often detectable before the provider announces it). The methodology and raw data are fully open.
Reviewer scorecard
“API access to the monitoring data is what makes this valuable for builders — you can pipe ClayHog's AI mention data into your own analytics dashboards and alert systems. The competitive intelligence angle is strong: knowing exactly which features competitors are being credited with in ChatGPT answers is actionable product intelligence.”
“The stylometric drift detection use case alone makes this worth bookmarking — being able to empirically verify when a model has been updated rather than relying on changelogs is genuinely useful for production systems that depend on consistent output behavior.”
“AI chatbot responses are nondeterministic — the same query returns different answers at different times, making trend tracking inherently noisy. The causal link between 'do X, improve AI mentions' is still poorly understood, and GEO best practices are largely speculative. You might be paying for data that's too noisy to act on reliably.”
“Stylometric analysis based on 40 prompts is a fragile basis for strong claims about model identity. Writing style varies wildly with prompt framing, temperature, and system prompt — the clusters here may be measuring prompt sensitivity as much as genuine model character.”
“AI-intermediated search is already capturing a significant share of discovery traffic, and that share is growing rapidly. In 18 months, GEO will be a standard line item in every marketing budget alongside SEO and paid social. ClayHog is early in an important category.”
“As AI-generated text becomes the default for much of the written web, tools that can map and distinguish model identities are going to be foundational for authenticity, attribution, and detecting when models are being impersonated or copied.”
“For content creators and indie brands, understanding how AI chatbots represent your work is increasingly important — potential customers are asking AI before they Google. Knowing whether Claude recommends your course or your competitor's is something I genuinely want to track.”
“For brand voice work this is immediately useful — I can finally have a data-driven answer to 'which model sounds most like our brand' rather than vibes-based prompt testing. The visual cluster map is intuitive and genuinely fun to explore.”
