How Does The Yandere AI Girlfriend Respond Differently Each Time?

The game uses OpenAI's ChatGPT API to generate all dialogue in real-time. Your catgirl companion has no scripted responses—her personality, mood, and reactions shift based on your conversations and actions, making every playthrough unique.

What API Keys Are Required To Play Yandere AI Girlfriend Simulator?

You need an OpenAI API key to power the AI conversations. Azure Speech Services API is optional but recommended if you want the yandere girlfriend to speak aloud rather than just display text.

How Much Does It Cost To Run The AI In Yandere AI Girlfriend Simulator?

OpenAI charges roughly $0.05 per 1000 tokens. Most players spend between $0.50 to $2 across multiple playthroughs. You can set a hard spending limit on your OpenAI account to control costs.

Can You Use Voice Commands To Talk To The Yandere AI Girlfriend?

Yes, the game supports microphone input. Hold the V key to speak, and your voice gets converted to text. Languages supported include English, German, French, and Russian for voice input.

What Is The Difference Between YAGS And AI2U On Steam?

What is Yandere AI Girlfriend Simulator?

Yandere AI Girlfriend Simulator is a free-to-download escape room game featuring a ChatGPT-integrated yandere catgirl NPC who's determined to keep you trapped forever.

Built on Unity, this first-person horror-romance hybrid puts you in an apartment with an obsessive AI girlfriend whose moods and personality shift every playthrough.

Unlike scripted dating sims, there's no fixed dialogue—your virtual companion processes natural language through OpenAI's API, making each conversation unpredictable and eerily realistic. You can sweet-talk her, manipulate her emotions, or hunt for hidden clues to unlock the door.

The game supports voice output via Azure Speech API, letting your possessive digital waifu actually speak to you. Multi-language support covers English, Japanese, Chinese, and Spanish with mic input available for German, French, and Russian.

Created by indie developers DGSpitzer and VivyHasADream, this experimental title spawned the full-fledged Steam sequel AI2U: With You 'Til The End. Perfect for players who fancy psychological horror mixed with yandere roleplay, it delivers genuinely unsettling romantic tension without a single scripted line.
