Ask four AI tools for the best product, and they usually disagree

1. They agree on first place in only 36% of categories

In 12 of 33 categories (36%), all four tools put the same brand first. In the other 21, at least two tools led with different names. A business that tops one AI tool's list can be missing from the top of the next.

2. 46% of brands are named by only one tool

Across the 33 categories the tools named 437 different brands. 203 of them (46%) came from a single tool. On average only 2.8 brands per category were named by all four. Being recommended by ChatGPT says little about Gemini or Perplexity.

3. Some tools give long lists, others very short ones

The average number of brands in one answer:

• ChatGPT9.5
• Claude8.9
• Gemini5.6
• Perplexity4

On a short list there is no room for a fifth or sixth choice. Perplexity, which searched the web live, named the fewest.

4. AI cites review sites and the brands' own pages

Perplexity listed its sources in 33 of its answers. These domains came up most often, counted once per answer:

• forbes.com5
• pcmag.com4
• zapier.com3
• albato.com3
• shopify.com3
• wix.com3
• nytimes.com3
• me.pcmag.com2
• slack.com2
• resources.rework.com2

Review and comparison sites like Forbes and PCMag lead the list, and the brands' own pages, like Shopify's and Wix's, show up next to them. What others write about a business matters, and so does what it publishes about itself.
