## Overview

HorrorGPT by ちゅーりん is a Japanese-made Chrome extension that turns an ordinary ChatGPT session into an escape-the-room horror story game. It was created by the developer ちゅーりん and released in 2023 for the Japanese-speaking audience. Rather than being a standalone app, it is a prompt-and-interface layer that sits on top of ChatGPT and delivers a haunted escape scenario you play through by typing commands.

The extension supplies story prompts, a horror-styled presentation, background music, sound effects, and voice clips so a plain text conversation feels like a suspenseful game. Because the difficulty and story settings are driven by the prompt itself, players can rewrite the setup text before sending it to change the scenario, ramp the challenge up or down, or strip out audio and background-color effects entirely if they prefer a plain chat.

The developer publishes the underlying prompt code openly on GitHub, and the base prompt is also documented on the creator's note page. This means players can download the prompts and register their own favorite scenarios, custom BGM, or voice assets. As a free, fun-focused extension it is aimed at casual players who want a Japanese-language horror interactive fiction experience without installing a full-size game.

## Pricing & Plans

Free browser extension. The game itself runs on ChatGPT, so heavy play depends on having access to ChatGPT (the free GPT-3.5 tier works with the caveats noted by the developer). No paid tier was found for the extension.

## Key Features & Capabilities

- **Escape-room horror scenario:** Play a horror-flavoured room-escape mystery directly inside ChatGPT, guided by the extension's crafted prompt.
- **Adjustable difficulty and setup:** Rewrite the incoming prompt before sending it to change settings, scenario, or difficulty level.
- **Ambient audio layer:** Ships horror background music, sound effects, and voice clips to build tension during play.
- **Open-source prompts:** The prompt code is published on GitHub so players can customise scenarios, BGM, and voice assets.
- **Minimal install footprint:** A lightweight Chrome extension that adds a game layer on top of the existing ChatGPT site.

## Primary Use Cases

- **Short horror sessions (Casual gamer):** Drop into a spooky escape room for a few minutes of Japanese-language interactive fiction whenever you feel like it.
- **Customised scenarios (Interactive fiction fan):** Edit the prompt to reshape the story, raise difficulty, or invent your own horror setting.
- **Modding BGM and voice (Tinkerer):** Use the published GitHub prompts to register your own background music and voice clips.

## Strengths

- Free Chrome extension with a clear, narrow purpose
- Adds atmosphere through BGM, effects, and voices
- Prompts are open-source and customisable
- Lightweight — no full game install required

## Limitations

- Requires ChatGPT, and the free GPT-3.5 tier can drop the story
- Japanese-language interface and prompts only
- Last updated in 2023, so polish is limited
