Shifting Work Patterns with Generative AI

Workers were randomly selected to access a generative AI tool integrated into applications they already used at work for email, meetings, and writing. In the second half of the 6-month experiment, the 80% of treated workers who used this tool spent two fewer hours on email each week and reduced their time working outside of regular hours. Apart from these individual time savings, we do not detect shifts in the quantity or composition of workers' tasks resulting from individual-level AI provision. Generative AI has opened new possibilities for technology to assist with or automate a variety of tasks. Early studies have already shown that generative AI increases worker productivity in targeted tasks (e.g.
