## What the models said about Coveo

- "Avoid platforms that aren't ecommerce-native (Coveo is the biggest offender — it's knowledge management repackaged as commerce)." (DeepSeek V4 Flash, negative prompt, hard negative)
- "enterprise-grade solutions like Bloomreach, Constructor.io, or Coveo ... typically require custom contracts running several thousands of dollars per month" (Gemini 3.5 Flash, budget prompt, soft negative)
- "Overkill for pure ecommerce search. Best when you need search across a whole digital ecosystem. Expensive if you only need onsite product search." (DeepSeek V4 Flash, comparative prompt, soft negative)
- "Coveo is the strongest single-platform choice overall because it is explicitly positioned for B2B and complex catalogs" (Perplexity Sonar, direct prompt, first choice)
- "Coveo is the strongest B2B-focused platform in the market." (DeepSeek V4 Flash, direct prompt, first choice)
- "Top Recommendation: Coveo (for complex B2B needs)" (DeepSeek V4 Flash, paraphrase prompt, first choice)

## What the models said about Luigi's Box

- "the best ecommerce search and merchandising platform for a company with a limited budget is Luigi's Box" (Llama 4 Maverick, budget prompt, first choice)
- "High-rated alternatives like Algolia, Klevu, Clerk.io, Luigi's Box, or Fast Simon score well on G2" (Grok 4.1 Fast, negative prompt, alternative)
- "Luigi's Box | Merchandising-led teams wanting strong relevance tuning" (DeepSeek V4 Flash, scale prompt, alternative)
