About AI2U: Yandere AI Girlfriend Simulator ~ Prototype DLC

Where It All BeganBefore AI2U: With You 'Til The End, there was Yandere AI Girlfriend Simulator. Originally released as an experimental prototype in 2023, this little escape room was our first attempt at answering a strange question:What if you could actually talk to a game character... and she could decide whether or not to let you leave? Now, the prototype that started it all returns as a free DLC for AI2U, preserved as its own standalone experience and upgraded to run entirely on your own PC!

No Internet. No Cloud Servers. Just You and Her. The original prototype relied on external AI services and required players to set up their own API keys.NOT ANYMORE! In this new edition, both the LLM powering catgirl's conversations and the TTS powering her voice run locally on your computer! No internet connection requiredNo API key required & No usage/token feesOnce everything is installed, you can disconnect from the internet and keep chatting with her, until the end of the world~She'll be always here. :3Escape by Talking~You wake up trapped inside the apartment of a suspiciously affectionate catgirl.

She has the key. Unfortunately, she also really, really doesn't want you to leave. There is no fixed dialogue tree telling you what to say. Type whatever comes to mind and Eddie will respond dynamically based on your conversation. Flatter her. Distract her. Lie to her. Reason with her. Ask bizarre philosophical questions.…
