Consumers are increasingly using artificial intelligence (AI) assistants in their personal lives as well as at work. While AI usage used to drop on weekends, that is less true today, digital intelligence and analytics firm Sensor Tower said. The company found that while the number of active users of OpenAI’s ChatGPT app was 5.8% lower on Sundays compared to the average day in the first half of 2024, it was only 2.5% lower in the first half of 2025. Similarly, the number of active users of ChatGPT on the web was 19.2% lower on Sundays than on the average day in the first half of 2024, it was 8.0% lower in the first half of 2025. By contrast, work-focused apps like Microsoft Teams and Salesforce’s Slack still see large drops in usage on weekends. “This makes [ChatGPT’s] app usage trends more similar to Google, which consumers rely on as a primary resource while working and outside of work alike,” Jonathan Briskman, principal market insights manager at Sensor Tower, wrote. Sensor Tower also found other signs that consumers are becoming more comfortable with using generative AI apps. The company said ChatGPT became the fastest app to reach 1 billion global downloads across iOS and Google Play; prompt data shows users are turning to ChatGPT for answers related to not just work and education but also lifestyle and entertainment; and the number of apps mentioning “AI” or AI-related terms increased by more than 200 in the first half. “This reflects how ChatGPT has not only reached a much broader user base, but how consumers are becoming increasingly comfortable using the tool for more varied use cases,” Briskman wrote.
