How AI changed Jørn Lier Horst's writing style, from action to static description

Jill Walker Rettberg compared Jørn Lier Horst's AI-assisted novel Den siste saken with two earlier books in the same series and found the AI-classified passages use more nouns and adjectives and fewer pronouns and verbs. She reports that AI-flagged sections lean on static setting descriptions and clichés such as humming, quiet and heavy air, while the pre-ChatGPT novels conveyed setting through character action. Horst has said he used ChatGPT only for research and sentence-level editing, and Rettberg argues that this level of use still changes the text itself.
