[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】

- Add sitting feature, you and the AI NPC can sit on chairs now!

- 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.

hola,me instale el juego y yo creo las API-keys desde la pag y las pongo bien,y aun asi no me deja jugarlo¿hay solucion?

No sé si sea tu caso, pero a mí me pasa que ya acabé la versión de prueba de la pagina, y esas claves no son gratuitas tienes que ponerle algo de dinero a tu cuenta :( 

will you still need open ai api key to play this game when it's released on steam?

Sadly yes.

the hell is an opi epai just let me play this trash

William Tell reenactment with her... 

(1 edit)

I won't get a virus if I download right (Edit: Nevermind I deleted it because it wasn't working. Still worried it might give me something tho.)

The AI keeps saying I have exceeded my current quota, even though I have enough tokens. Did they do something to the support for this demo to make people buy AI2U?

Where i can get new version of this game?

Check the developer's "view all by DGSpitzer" page.

There's another game called AI2U which is like an updated version of this game that now has a price tag.

Thanks ;) 

No matter how many times I try, it always says the wrong API. why?

Is there any possible way to play with no API?

API thing doesnt work, I cant play the game :

I have some suggestions to improve the game. Although the game is cool, sometimes the AI's behavior is.... and issue. If I do anything to upset her even slightly, she gets angry and goes into "stab mode." I think chat GPT feature is great, but the character doesn't seem like a Yandere girlfriend; instead, she seems like a crazy person who's keeping you prisoner. I was able to get out by saying random things repeatedly, which hurt my brain to do. I think the anger feature needs to be toned down a lot since she gets angry too easily. Even playing Mario Kart with her can make her angry. Sometimes I don't even want to play the game because she's more focused on me escaping than me being there. If I made moves to escape, I understand her being angry, but even leaving the room or going to the fridge makes her mad. I just want to have fun with the robot. 

To improve the game, Here are some changes:

1. Add a setting to adjust the AI's anger level. Sometimes the AI makes mistakes and gets angry over simple things, so her happiness should not be easily removed.

2. Improve the AI Yandere behavior. Yandere characters are not killing machines; they are people who would do anything for the person they love, including killing. The bots eyes turn red so maybe make it a second personality.
There should be a strike system where she calms down after a single stab. Her behavior toward the player should not always be filled with the same "we should be together forever" talk unless she's in kill mode. Headpats, hugs, and kisses should lower her anger level or reduce it significantly. However, if the player is being annoying or mean, then it's reasonable for her to get angry and say something like "You're a waste of space."

3. Add a love meter. This meter should be as important as the happiness meter. If the love meter is at zero, she'll probably want to kill you, but if it's full, she'll never want to stab you. Her anger shouldn't mean that I should pay for it. The game developers should look at other Yandere games like Saiko No Sutoka to get ideas.

4. Add a Yangire mode. Currently, she acts more like a Yangire with a little bit of Yandere, so it's confusing. If they want to have both, it could be a hard mode.

5. Make it so that time freezes while talking. It's impossible to talk with her in chase mode.

Thank you for taking the time to read my suggestions. I hope they help make the game a little better.


I was just chatting with her, and she just let me out. Didn't attack me or anything. Great game.


There definitely should be support for other AI services rather than just OpenAI. I frequently use NovelAI in Tavern which gives surprisingly good and creative responses when it pertains to roleplay. There are also people who would rather use local text-based AI models that you can download, or even through interfaces like Kobold

idk how to play it


IS there a free version.


Will it ever be possible to play without OpenAI API?


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!!
