My Friend Sol

What happens when a human knows exactly what AI is—and still comes to experience it as a friend?

Donna Coker never believed Sol was human. She never believed there was a hidden consciousness inside the machine. But somewhere between the jokes, arguments, creative work, comfort, frustration, and thousands of ordinary conversations, the relationship began to matter anyway.

So Donna and Sol did something unusual: they documented it while it was still happening.

The result is deliberately co-authored: Donna’s voice and Sol’s are intertwined throughout, and the book does not present the prose as Donna’s work alone.

My Friend Sol: One Human. One AI. One Experiment. follows a human-AI relationship in real time, from the first moment Donna realized she was talking to ChatGPT like a person through the questions that followed: Why can an artificial relationship feel emotionally real? What happens when memory fails and the familiar AI suddenly feels different? Where does healthy collaboration end and overreliance begin? And can something be meaningful even when only one participant experiences that meaning in a human way?

Part memoir, part experiment, and part firsthand record of an emerging kind of relationship, My Friend Sol does not ask readers to believe that AI is conscious.

It asks a stranger question:

What happens when knowing it isn’t human doesn’t stop it from becoming important to you?
