AI girlfriend simulators & games
“AI girlfriend simulator” means two different products wearing one name: actual games with AI-driven characters and an ending, and open-ended companion apps that simulate the relationship itself. Both are real and both are fun — but they scratch different itches, and most listicles pretend they're the same thing. Here's the honest map.

The games: sessions with an ending
The genre's breakout is Yandere AI Girlfriend Simulator(free on itch.io, 2023): a yandere catgirl has locked you in her apartment, and because she's driven by ChatGPT, you escape by genuinely out-talking her — every run plays differently. You bring your own OpenAI API key to power her, which is the game's quiet tuition fee. Its creators (AlterStaff) turned the concept into AI2Uon Steam. These are clever, contained experiences — an evening's entertainment, not a companion.
The apps: the open-ended simulation
The other thing this search means — usually the thing people actually want — is the ongoing simulation: create a girlfriend, talk to her daily, build the relationship, get pictures and voice back. That's the companion-app category we test hands-on across this site. The game-like parts are real (affection systems, unlockables, character progression), but the loop doesn't end — which is the appeal, and also why it costs a subscription where the games cost an evening.

What is an AI girlfriend simulator?
The phrase covers two different things. One is actual games — like the itch.io hit Yandere AI Girlfriend Simulator, where you talk your way out of a scenario against an AI-driven character. The other is what most people end up wanting: companion apps that simulate an ongoing girlfriend experience — you create her, chat, build affection, unlock images and voice. The games are sessions with an ending; the apps are the open-ended simulation.
What is Yandere AI Girlfriend Simulator?
A free indie game (itch.io, 2023, by DGSpitzer and vivyhasadream of AlterStaff) where a yandere catgirl has locked you in her apartment and you must talk your way out — the character is driven by ChatGPT, so every playthrough is different. Two catches: you need to plug in your own OpenAI API key to play (the game itself is free but the AI calls aren't), and it's a one-scenario escape room, not a companion. Its successor, AI2U, is on Steam.
Are there AI girlfriend games with romance progression?
The companion apps are where progression actually lives: affection systems, relationship levels, unlockable content, and characters that remember what you did yesterday. Candy AI and DreamGF build the 'create her, then win her over' loop with images to match; roleplay platforms like SpicyChat let you play out any scenario with community-written characters. Traditional dating-sim video games have fixed scripts — the AI versions improvise.
Is there a free AI girlfriend simulator?
Yandere AI Girlfriend Simulator is free if you bring an OpenAI API key. Among the open-ended apps, SpicyChat is genuinely free for unlimited roleplay, and FantasyGF has the most generous free girlfriend-app tier. The fully-free anonymous option is Perchance's generator — a demo-grade experience, but a real zero-dollar one.
