NBC News Chief Technology Analyst Joanna Stern spent one year incorporating artificial intelligence into her daily life to test AI companions [1].

This experiment highlights the growing intersection of human emotion and software. As these tools become more sophisticated, understanding their psychological impact is critical for users and developers alike.

Stern said her findings on the NBC News "Here's the Scoop" podcast. The project served as research for her upcoming book, "I Am Not a Robot," which examines the realities of living with AI [1].

During the year-long trial, Stern explored how AI companions function and the role they play in a user's routine. The testing focused on the ability of these systems to simulate companionship and provide emotional support through conversational interfaces [1].

Industry data suggests a significant appetite for these tools. The Character.AI platform, for example, has more than 20 million users [2]. This scale indicates that millions of people are already utilizing AI for social or creative interaction.

However, the impact of these digital relationships remains a point of contention. Some reports suggest AI companions act only as a temporary fix for loneliness and isolation, potentially doing more harm than good [3]. Other perspectives suggest these tools are not replacing human connections, implying they are not inherently harmful to the user's social fabric [4].

Stern's work seeks to bridge this gap by providing a first-hand account of the integration process. By documenting the nuances of her interactions, she aims to clarify how these systems influence human behavior over an extended period [1].

The tension between the massive user growth of platforms like Character.AI and the debate over emotional harm suggests a lag between technological adoption and psychological understanding. Stern's research reflects a broader cultural shift where AI is moving from a productivity tool to a social surrogate, necessitating a deeper analysis of how digital intimacy affects human mental health.
