Claude tops UK AI satisfaction survey as Grok and Siri fall behind

Claude recorded the strongest satisfaction score among current and former users of major AI assistants, according to TechRadar’s report on a new YouGov survey. Anthropic’s assistant posted a 56.2 net satisfaction score, ahead of Google Gemini at 46.5 and OpenAI’s ChatGPT at 46.0.

The data comes from YouGov’s BrandIndex tracking system and covers respondents in the UK surveyed between March 1 and July 31, 2026. YouGov examined two related measures: the top 10 AI assistants by satisfaction among current and former users, and the difference between satisfaction among people who still use a service and those who have stopped.

Claude’s lead is notable because its score was strongest across the combined current-and-former-user measure. It also recorded the highest former-user satisfaction score and the second-highest current-user satisfaction score, according to the report. That suggests the assistant’s reputation extends beyond its active user base, although the survey does not establish why people rate it more favorably.

The lower end of the table produces a sharper contrast. Grok and Siri were the two most prominent laggards, while Amazon Alexa scored 42.6 and Microsoft Copilot scored 37.2, placing those products in the middle of the list despite the size of the companies behind them.

YouGov’s current-versus-former-user comparison also exposed unusually large gaps for several services. ChatGPT’s score was 63.7 points higher among current users than former users. The corresponding gaps were 62.5 points for DeepSeek and 62.4 points for Grok. Grok’s former-user score was particularly weak at -4.7.

Those figures should not be read as a direct ranking of technical performance. The survey measures user satisfaction and reputation, not model accuracy, reasoning benchmarks, latency, pricing, or feature breadth. It also does not explain how access affects the results: assistants such as Siri and Alexa are readily available on consumer devices, while users may need to deliberately seek out tools such as Claude or ChatGPT.

That distinction matters when comparing products with very different distribution models. A built-in voice assistant can reach people who never chose an AI service, while a standalone chatbot is more likely to attract users who actively want one. The survey reports the satisfaction gap, but does not separate those factors or identify which specific experiences drove respondents' answers.

The result nevertheless lines up with another recent signal around Claude’s appeal among developers. A self-selected survey of 138 developers previously covered by us found that 75% preferred Claude Code, although Codex performed better on price, usage limits, and app workflow. That earlier result concerned a narrower professional audience and a different product category, so it cannot be combined directly with YouGov’s UK consumer-facing assistant data; it does show that Claude’s favorable perception is not limited to one type of user survey.

The YouGov report does not provide a technical explanation for Claude’s lead, nor does it say how many people responded or publish the full score for every assistant in the top 10 in the supplied report. What it does show is a clear reputation split: Claude led the combined satisfaction measure at 56.2, Gemini and ChatGPT clustered around 46, and Grok’s former-user score dropped below zero.
