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

This game uses generative AI to produce real-time, dialogue-based explanations, narrative content, and key summaries during gameplay (with optional AI-generated voice output). The generated content dynamically adapts based on player inputs, such as uploaded papers or text, as well as in-game choices, and is used solely for in-game presentation. Players are advised not to input sensitive personal information and to independently verify any important information.

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.
