The AI service lists differed slightly between waves. March listed DeepSeek and Character.AI, which August dropped, and August described Meta AI with examples of where it appears, such as WhatsApp and Instagram.
【方法】调查中AI服务列表的变化可能影响结果比较。三月调查包含DeepSeek和Character.AI，而八月调查没有，同时对Meta AI的描述更详细。这种变化可能导致用户报告偏好的服务不同，影响使用频率数据的可比性。
The two waves measured days of use differently. March asked a single overall question whose response options were these three groups, while August asked day counts for each service separately, which we collapsed into the same groups.
【方法】调查方法存在重要差异：三月询问整体使用情况，而八月询问每个服务的单独使用天数。这种差异可能导致数据解释偏差，因为八月的方法可能低估实际使用频率（例如，使用多个服务的人可能被计数为使用天数而非总使用次数）。
