Attitudes Toward AI Brands Split Sharply by Generation: Claude Holds a 7x Edge Among Gen Z

Attitudes toward AI assistants can no longer be captured by a single, universal metric — a new YouGov study makes that clear. When Americans who had used generative AI in the past 30 days were asked which tool they preferred, the answers split sharply along generational lines. ChatGPT remains the leader across every age group, but Anthropic's Claude tells a completely different story.

The numbers tell the story: ChatGPT is preferred by 44.4% of Gen Z users versus 24.5% of Baby Boomers. Gemini ranks second, performing best among Generation X at 22.8%, while among Gen Z that figure drops to 14.3%. Claude follows an entirely different trajectory: 10.6% of Gen Z respondents prefer it, compared with just 1.4% of older users — a roughly 7.6x gap, the widest generational divide of any major AI brand in the study. Microsoft Copilot shows the opposite pattern, preferred by only 4.4% of Gen Z but 12.3% of older users. Voice assistants like Siri and Alexa follow a similar pattern: solidly established among Generation X and older, but barely registering with younger users.

This is no coincidence — it reflects which AI tool first worked its way into each generation's daily habits. Anthropic built its first-ever Super Bowl ad around this shift, even though Claude had never previously been associated with advertising, and followed up in the spring by launching products like Cowork and Claude Design while easing usage limits. That strategy bets on an audience that trusts software companies directly, which naturally skews younger. OpenAI, by contrast, took a more traditional route — a Super Bowl campaign built around Codex and steady refinement of ChatGPT's default model — delivering consistently strong results across every generation.

There is an important nuance here, though: "preference" and "consideration" metrics show how firmly a brand has lodged itself in people's minds, not how much they are trusted. A separate YouGov study found that only 28% of Americans fully trust the answers AI assistants give. In other words, strong brand awareness doesn't automatically translate into trust — a distinction marketers and SEO professionals need to account for separately.

The study also carries real practical weight: different generations use AI for different purposes. Web search stays roughly flat across all age groups, at around 38-40%, which debunks the assumption that young people have abandoned search-style queries altogether. But when it comes to content creation, the gap is stark: Gen Z uses AI for idea generation three times more often than older users (33.6% versus 10.5%), and the gap widens further for coding — 14.8% versus 1.6%.

These findings offer clear guidance for practitioners: brand monitoring should be split into two separate tracks — one measuring brand awareness and standing, the other measuring trust. If your audience skews toward Gen Z or millennials, content should be tailored to the tasks they hand off to AI — summarizing, editing, brainstorming. If your audience is older, traditional search queries and voice assistants remain central. Brand awareness and brand trust are two entirely different things, and marketers who miss that distinction risk making a costly mistake.
