Market research firm YouGov published a survey measuring user satisfaction with various artificial intelligence services. The data were collected between March 1, 2026 and July 31, 2026, and the results highlight clear differences among competing AIs.
Key findings
- Anthropic's Claude received the highest satisfaction score at 56.2 points.
- Google Gemini placed second with 46.5 points.
- OpenAI's ChatGPT ranked third with 46 points.
These figures come from YouGov's top 10 ranking and indicate a notable lead for Claude in terms of user satisfaction.
Lowest-ranked services
At the lower end of the list are two well-known services: Grok, associated with Elon Musk, scored 24.6 points, while Apple Siri finished last with just 23.7 points. According to the survey, Siri is the AI users are least satisfied with.
Other familiar systems, such as Amazon Alexa and Microsoft Copilot, occupy middle positions in the field.
Changes in satisfaction over time
YouGov also examined how satisfaction levels changed for individual AIs during the measurement period. The largest increase was shown by the Chinese DeepSeek, with Claude in second place on this metric and Perplexity AI coming in third.
When looking at the magnitude of change in concrete point values, the ranking was reported as follows:
- ChatGPT: 63.7 points of change
- DeepSeek: 62.5 points of change
- Grok: 62.4 points of change
Grok is notable because, despite a large change figure, its earlier user satisfaction was particularly low, leaving its current score (24.6) near the bottom of the list. These numbers suggest there is substantial room for improvement for Elon Musk's AI to raise user satisfaction.
Why the results matter
The YouGov data show that user satisfaction is uneven across the AI market: some providers (Claude, Gemini, ChatGPT) achieve relatively high scores, while others fall behind considerably. Tracking changes over time helps identify which platforms are improving quickly and which are failing to meet user expectations.
The survey's detailed results and the top-10 scores are based on YouGov's data collection covering March through July 2026.
