Escape the Grind

The developers describe how their game uses AI generated content like this:

AI image generation tools were used to create some promotional artwork and store page images. The game does not connect to any AI services or generate AI content during play.

Required on Steam store pages since 2024. It covers content that ships in the game, on its store page or in its marketing — Valve does not require a disclosure for AI tools used during development, so this says nothing either way about how the game was made. Check it on Steam.
