AI Girlfriend Game: What to Play, What It Costs, What It Remembers

Quick picks, for people who just want a name

If you want a game — something with a story, a goal and a finish line — the short answer is AI2U. If you want a companion who is still there next month, it's Replika. Everything else on this page sits between those two poles, and the gap matters more than any feature list.

Pick	Best for	Price
AI2U	Story-driven AI dating with a horror twist	Paid, one-time
Yandere AI Girlfriend Simulator	A prototype for tinkerers	Name your price plus OpenAI API costs
Whispers from the Star	Voice-first chat with one character	$9.99 list
Replika	Levels, XP and room decorating	Free; Pro about $5.83/month billed annually
Talkie	Collectible cards (SFW)	Free; Talkie+ $9.99/month
Nastia	Uncensored roleplay and voice messages	Daily limits; $15.99/month
Candy.ai	Adult scenes and photoreal images	5 messages free; from $3.99/month billed annually
OurDream AI	A huge community character library	From $9.99/month billed annually

We compared these on the same criteria — what the store page says, what the pricing page charges, what the privacy policy admits. Where a claim can't be checked ("fully AI-driven," "over 800,000 users"), we say so. Nobody paid for a place on this list.

Two kinds of "AI girlfriend game," and they don't behave the same

The first kind is a game in the ordinary sense. You install it, you play it, it ends. AI2U is a 3D escape-room romance-horror hybrid. Whispers from the Star is a stranded-astronaut story told through voice calls. You finish them the way you finish a book.

The second kind is a chat app with game mechanics bolted on: experience points, coins, levels, collectible cards, affection meters. Replika gives you XP per message and rewards you with coins and gems for clothes, traits and furniture. Talkie runs on gacha pulls. These aren't games you complete — they're loops you stay inside, and the loop is usually designed to nudge spending upward.

Neither kind is dishonest. But people arrive at "AI girlfriend game" searches wanting one and land in the other, then feel cheated. Decide which you're after before you download anything.

The actual games

AI2U: AlterStaff — the most complete thing on this list

A yandere girlfriend, a locked 3D space, and three settings to work through: an apartment, a forest cabin and a space station. The cast includes a catgirl, a witch, an AI hologram and a siren, and there are multiple endings. You can type or speak into your microphone.

What makes it interesting is the split: the conversations run on an LLM with text-to-speech, while the art and story are human-made, according to the Steam page. So you get authored structure with improvised dialogue on top. It entered Early Access in January 2025, with a full launch in August 2026, and Steam user reviews sit at Very Positive. Critics liked the AI and found it repetitive — which is a fair summary of the whole genre.

Two caveats. First, it's romance-horror, not adult: the store listing says no explicit content and the game ships with built-in filters. Second, its chats pass through third-party AI services, so you're not talking to your own machine. If you want something else in this vein, our AI Dungeon alternatives by complaint piece covers the story-driven end of AI play more broadly.

Yandere AI Girlfriend Simulator — a prototype, priced like one

An itch.io prototype built around a locked room: talk the catgirl round, or find the clues. It's name-your-own-price, runs on Windows, macOS and Linux, accepts voice input, and has a Prototype DLC on Steam. It also requires your own OpenAI API key, which means you pay OpenAI per conversation on top of whatever you chose to give the developer.

This is a tinkerer's toy. It's rough, it's unfinished, and it expects you to understand what an API key is. If that sentence made you tired, skip it.

Whispers from the Star — short, strange, voice-first

From Anuttacon: Stella is a student astronaut stranded somewhere she shouldn't be, and you reach her by voice, text or video call. There's no fixed script. She reacts to what you actually say and remembers earlier choices, and the $9.99 Steam listing (Windows) is honest about the format.

It needs a microphone, and Stella's story ends. She isn't a lasting girlfriend; she's a well-made short story you talk your way through. For the price of a takeaway, that's a reasonable trade.

Gamified companion apps

Replika — the one that started the pattern

XP per message, levels, coins, gems, daily rewards, clothes, traits, room furniture. Replika turned companion chat into a progression system before anyone else did, and the loop still works. Romantic Partner mode requires Pro, which the App Store lists at about $69.96 a year — roughly $5.83 a month.

It's also strictly SFW, and the Italian privacy regulator fined its maker €5 million in 2025. That fine is the single most useful fact on this page if privacy is your concern; read our AI girlfriend reviews hub for how other apps compare on the same measure. We rate Replika's memory and privacy separately from its charm, and its overall score is –.

Talkie — cards, gems and a disappearing app

Talkie is built by MiniMax, a Chinese company, and its core mechanic is the gacha pull. Gems buy character cards; rarer cards unlock traits or story modes. Talkie+ is $9.99 a month, Pro $24.99. Everything is SFW, and the card design is explicitly there to drive spending.

One practical note: Talkie was pulled from the US App Store in December 2024. Check availability before you plan around it. Our apps like Character AI roundup covers what people move to when a platform disappears like that.

Nastia — uncensored, with a limit behind the word "free"

Web-only, no app store: you add it to your phone's home screen. You customize name, look, backstory and voice, and it advertises persistent memory — your name, preferences, inside jokes — while staying in character. It also allows NSFW without the usual filters, including uncensored voice messages and selfies in a cloned voice.

The company claims over 800,000 users; that's their figure, not something we can verify. Paid users get multiple companions with distinct traits and even group chats. The homepage says "free forever," and technically it is — with daily limits. Uncapped use is $15.99 a month on the Unlimited plan. We've scored Nastia's memory and value in 9.4, and if you're weighing it against the big picture app, our Nastia AI vs Candy AI comparison goes deeper.

Candy.ai — pictures first, conversation second

You build her look, personality and voice, and selected characters get Live Action interactive video. The renders are genuinely realistic. Premium is $13.99 a month, or $3.99 a month billed annually.

The free starter account is 5 messages and one image. Monthly media tokens sit around 100 and disappear fast once you're generating pictures. We rate Candy.ai 9.8 overall, and its image score is well ahead of its memory score — see our Candy.ai review for the token maths in full.

OurDream AI — unlimited messages, metered pictures

Unlimited messages, 1,000 dreamcoins a month (about 200 images), voice calls and a library of millions of characters. It's $9.99 a month billed yearly or $19.99 month to month.

Two things to know. Memory leans heavily on recent messages, so long stories fade. And media is blurred if your subscription lapses — you don't keep what you made. We rate OurDream AI 9.7; the OurDream AI review breaks down the dreamcoin economy.

Secrets AI — for people who want the story to hold

Editable Lorebooks, group chats of two or three companions, and proactive messages that arrive without you prompting. Premium starts at $19.99 a month; Ultimate is $39.99. The starter tier gives 20 messages a day and no image creation at all.

It's the pick here if continuity matters more than pictures. We rate Secrets AI 9.9, and the Secrets AI review covers memory and cost together, which is the only way that trade makes sense.

Other dating games worth a look

Couple.me, from FAB AI LTD in London, lets you customize name, looks, voice and personality. It's a chat app rather than a game, and it behaves like one.

AI Girlfriend: Dating Sim on the Epic Games Store has beach and cafe dates, gifts and date tokens. The developer calls it fully AI-driven; that claim is unverified, and the token structure suggests a fairly conventional dating sim underneath.

Two things that look like AI games and aren't: ERROR:Ai.lien, a 2026 horror-romance that the developer says isn't AI-powered, and AI Perfect Girlfriend, which is a scripted visual novel. Neither is dishonest — they're just not what the name suggests.

For completeness: Grok's animated companions, which came with an affection meter, were retired in September 2026. Features vanish. Don't build a routine around one.

What "free" actually gets you

Game or app	No-cost version	Main limit
Yandere AI Girlfriend Simulator	Full download	Needs your own paid OpenAI API key
Replika	Friend chat, levels, rewards	Romance needs Pro
Talkie	Chat and some card pulls	Gems and message walls
Nastia	Uncensored chat	Daily limits
Candy.ai	5 messages	Barely a demo

Free plans are good for testing whether you like the vibe. They are not a way to play properly for nothing. Treat "free forever" as marketing copy and read the limit line underneath it — our piece on what you actually get before you pay walks through the pattern across apps.

Is there a free AI sex game?

No. Not in the sense people mean when they search for it.

The Steam games here deliberately avoid adult content — AI2U ships with filters and says so on the store page. Explicit play happens on web platforms, and those platforms lock images, voice and video behind a subscription almost without exception. Sites promising everything with no account are pushing cracked downloads or ad-filled browser games, and both are a bad trade: one is a malware risk, the other is a waste of an evening.

If explicit content is the actual requirement, pick a web platform and pay for the tier that includes media. If it's the game you want, accept that the games are filtered and enjoy them as games.

Game or chat app: how to choose

Ask yourself what you want to be doing in twenty minutes. If the answer is "finishing something," buy AI2U or Whispers from the Star. If it's "talking to someone who knows me," you want a companion app with real memory — and you should judge it on memory before anything else, because pictures are easy and continuity is hard.

If the answer is "I don't know yet," spend a week on free tiers. Five messages on Candy tells you whether you like the pictures. A day of Nastia's limits tells you whether uncensored chat is the draw. Replika's free friend mode tells you whether levels and decorating motivate you or annoy you.

One warning about the gamified apps: affection meters and card pulls are designed to escalate spending, and they work. Set a budget before you start, not after.

Privacy: the part nobody reads

Every conversation on every platform here goes to a server. None of them encrypt chats end to end. That's the baseline, and it applies to the paid tiers too.

It isn't theoretical. In 2024, a breach at Muah.ai exposed roughly 1.9 million email addresses along with private prompts. The prompts are the uncomfortable part — people write things to these apps they wouldn't say out loud.

Practical habits, none of them dramatic:

• Use a separate email address for companion apps.
• Don't give your real name, workplace, address or any private detail you'd mind seeing in a leak.
• Never upload photos of real people.
• Deny camera and microphone permissions unless the app genuinely needs them.
• Download PC games only from Steam, itch.io or official stores — never a mirror site.

One more thing, not about security. AI companions offer judgment-free support, and some adapt to your mood in real time, which can feel genuinely good. They still can't replace real people or real-world plans. If your social life is shrinking rather than holding steady, that's worth noticing.

Bottom line

The best mix in 2026 is real games on one side — AI2U, Whispers from the Star — and gamified apps with levels, cards and affection meters on the other. Both are legitimate; they answer different wants. Treat the companion as a story you're playing, not a substitute for a world, and you'll get what you paid for.

Try free first. Read the privacy policy before you type anything you'd regret. And pay only for what you'll actually use — the monthly token allowance, not the fantasy in the ad.
