HorrorGPT by ちゅーりん is a plugin that allows you to play horror-themed novel games on ChatGPT. With this plugin, you can rewrite the prompt before sending it to customize the settings and difficulty level.

The program also provides the option to download and register your own favorite prompts, background music (BGM), and voices, as the developer has made the code publicly available.

Please note that in the free version, when inputting phrases like "look up" directly, the conversation may not flow smoothly. It is recommended to address the AI by name, for example, "Kai, try looking up 〇〇." Additionally, if a long setup sentence appears at the beginning, reloading or resending the prompt until it becomes shorter can help the conversation continue smoothly.

The program credits the following sources for its audio:

• BGM1: "Sunset Abandoned School" by Kazuchi (DOVA-SYNDROME)
• BGM2: "This Romance" by Khaim (DOVA-SYNDROME)
