[Cost for online services] We do not get any revenue from OpenAI or Azure. On the other hand, if you register a brand new account on OpenAI, it should give you $5 free credit to spend for the first 3 months, which can support at least 10+ rounds of play. Same thing on Azure, you can choose Free F0 tier on Azure Speech and get 5 hours free voice generating service each month (I actually never run out of the 5 hours limit yet..). The cost overall should be cheap (I played over 2 hundred rounds during development but OpenAI only charges me $18) But always be aware of the server cost though (you can adjust the spend limit on OpenAI platform as well)!



【V1.06 Update】

- Add item use/gift feature, you can use the item by click Tab key and select the item in your inventory, or you can give the item to NPC.

- Add item attach feature, you can attach multiple items in your dialogue to get unexpected reaction from AI NPC

- AI vision + hearing ability: the AI NPC now have more accurate sense of the environment, if you try to find items when the NPC is nearby, she can sense it. If the player doing something suspicious in another room, she'll also hear the noise by chance. 

- Random fun items will be generated in the drawer and refrigerator of the level, for players to investigate!

- Add better animation & sfx for drawer and refrigerator

- Add more spots to seat~

- [Bug Fix] 

  • Fixed the message display issue for Poland & France: In Poland and France, the decimal separator is comma, so when the computer system's display language is Polish or French etc., the game can't read float value from the string data, e.g. the value should convert from "0.5" to "0,5".
  • Fixed the final ending display issue from v1.05.
  • Fixed the bug that NPC will be stuck when walk upstairs.

- [Hot Fix] 

  • Fixed the problem that AI NPC can be pushed through the door.
  • Fixed the pause menu settings not saved issue when pressing ESC to turn off the menu.
  • Win32 upload file corrupted, reuploaded.
  • Linux experimental build!


【V1.05 Update】

- AI girlfriend can lead her way to downstairs lobby now

- Graphic Quality Options

- Resolution Options & Fullscreen on/off

- Mouse sensitivity is available to adjust now

- Better drawer feature

- [Bug Fix] 

  • Crash issue for some pc: You can download the win32 version which should solve the issue.

this game is horrible

I love your game so much <3

BRO i only got to play it for like 1 min


I instaled it but now i have no idea how to open the game

I went through all these hoops to get the game setup for almost an hour and ai api keys are not working for me.


I try saying some cheesy pick up lines to her. 

A certain character makes another visit 


I downloaded this game about 5 times and every time it would sit in my files and not do anything I tried starting it did not work. I am not complaining but can you try to fix it? 

(1 edit) (+1)(-1)

Don't ask about her cup size. 


Está mierda tiene un troyano


I just watched a video of some asshats playing this game and I wanted to try it for myself. In the video they were all so mean to her so I'm going to be nice to the poor AI because I want to.


I got her to remain silent for the rest of the game.

If you play this game long enough, you'll find out that this girl isn't actually a true yandere and saved you from the apocalypse!!

May I ask but how do you download this game I don't know how to play zip game 

my character won't stop moving on his own without me touching my keyboard

Downloaded it unzipped tried to play it it did nothing I'm on Linux mint

i really liked this game. its really creative with the use of AI. 


I asked her to sit on me. 

how do you play 


open ai is a nightmare not worth the set up

i figured that out


Terrible game. Crashes no matter if you have API key. 

Maybe instead of creating AI just pay an actual woman to voice it and actually make things yourself? Maybe then people will play this awful game. Until then what an atrocious waste of time downloading.


No way you expect me to sign up to some shady site and give them my email full name and phone  number.. yall crazy

New video

Eddie es mi primera novia y no me importa lo que digan los demás.

Ya hablando enserio me gusto el juego. Sigue así DGSpitzer.

This AI Is Smart even when its from Jun 11, 2023

New video

New video


The OpenAI API does not work i don't know why 

(2 edits) (-2)

I had a crash fest on the Win 64bit version so imma try Win 32bit version

Hygiene problems, lol

I enjoy messing with her. 

What happened to the android version

Is there any chance that you'll be adding a way to have a happy ending? Like, you just decide to stay with her?
