Long-term real-world usage and outcomes of GhostWriter

Investigate how participants use GhostWriter or similar large language model-powered writing systems over extended periods in real-world tasks, and characterize long-term interactions and outcomes that are not observable in short, lab-based sessions.

Background

The evaluation consisted of two one-hour sessions focusing on editing and generative writing tasks. Due to this short-term setting, the paper design does not capture longitudinal behaviors or real-world adoption patterns.

The authors explicitly note the inability to observe longer-term usage and provide the example of understanding how participants would use such systems over extended periods for real-world tasks, identifying this as an unresolved question.
