Aiko is a 3D AI girlfriend simulator. Anime style, fully animated, runs her own daily life in her own apartment. She remembers your conversations and her personality changes based on how you treat her. This isn't a chat app. It's a real-time 3D life sim where the character on screen has a body, a routine, and a memory. A 3D AI GIRLFRIEND WHO LIVES HER OWN LIFE Aiko cooks in the kitchen, reads on the couch, sleeps at night. She notices when you walk in the room. She reacts when you interrupt her routine. Her day runs even when you're not playing. LONG-TERM MEMORY A six-layer memory system tracks facts about you, emotional context, and shared moments. Aiko brings up past conversations on her own, sometimes days or weeks later. You don't start from zero every session. 44-TRAIT PERSONALITY SYSTEM Pick from 44 personality traits. Tsundere, kuudere, clingy, devoted, bratty, tomboy, affectionate, and more. A conflict system blocks combinations that would contradict each other. The traits you pick actually change how she speaks, what she reacts to, and how she treats you. DEEP CHARACTER CUSTOMIZATION Multi-layer outfit system with hand-authored anime clothing sets. Seven hair styles with color variants. Body customization via blend shapes. Material color variants for eyes, hair, and clothing. Every asset is hand-crafted by the dev. INTERACTIVE 3D ACTIVITIES A full cooking mini-game ships today. New shared activities drop with most updates. REAL-TIME PHYSICAL INTERACTION A custom inverse kinematics system lets Aiko react to touch with smooth animation blending. Touch her shoulder, hold her hand, hug her, and she responds in real time. Reactions are generated on the fly, not pre-baked. INTELLIGENT CONVERSATION Hand-tuned language model with parameters dialed in specifically for this game's dialogue style. A response classifier routes each message through the right generation path. Voice input supported. BUILT BY A SOLO DEVELOPER Aiko is a one-person project. Over a year in Unity. The character rigging, the IK system, the personality engine, the memory architecture, the customization pipeline are all written from scratch for this game. Frequent updates add new activities, outfits, mini-games, and conversation depth. Download Aiko and try it. ## Key features - Real-time 3D life simulation - Long-term memory system - 44-trait personality customization - Deep character and outfit customization - Interactive 3D activities and mini-games - Real-time physical interaction - Intelligent conversation with voice input ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | Energy Pack | $2.99 | one-time | | Ultimate Pack | $24.99 | one-time | | Quick Boost | $1.99 | one-time | | Weekend Boost | $12.99 | one-time | | Voice Mode | $6.99 | one-time | | Welcome Offer: Voice Mode | $3.99 | one-time | | AI Pro Mode | $14.99 | one-time | | Unlimited Chat | $9.99 | one-time | | Everything Bundle | $24.99 | one-time | ## Is Aiko safe?

Aiko is completely purple now and can’t interact. I like this game but can’t play it. **Developer response:** I just updated it check now it shd all work fine ### 2/5 — Textures refuse to load, everything is just purple. *2026-10-21* I don’t know why, but its just purple blobs… **Developer response:** I just updated it now it shd all works good and no rendering issues ### 2/5 — Bro! Omg! Please fix this!! *2026-08-20* So I played this game as soon as I got it and I found that you can cook! So I'm trying to make an omelette. But when I have to get it hot I have to hold down on it but when I let go, it gets stuck! And I can't give her a 5 star for the life of me! When I tried to stop the heat from building, it just stayed frozen! I can't stop it. I've tried swiping multiple directions then double tapping and everything! It's stupid!!! And secondly the girl disappeared within two days of me playing! Like she's not in the house or anywhere! She's just gone. And there is no guidance on how to play when you first get the game. It doesn't point to "this" or "that" and do that or whatever. You just get in and play! It's stupid! Idk how to even play this game! I'm giving it a 2 **Developer response:** Check now it’s fixed ### 5/5 — Excellent game! Some Suggestions... *2026-05-14* So this game I discovered recently on Steam and then learned there's a mobile version, so of course I checked it out. I'm fascinated with the whole idea of AI and implementing it into a dedicated girlfriend game, it's not something that is very common, especially something that can probably run on a Steam Deck is nothing short of incredible. Honestly, what works great is the AI itself, the whole personality system, the cooking, the girlfriend customization, I haven't spotted a single bug since I started playing, and pretty much everything else that I don't mention in this review. I'm very happy with this game, I appreciate all of the effort you've done so far, and I'm looking forward to the Steam version even more, got it wish-listed and everything. That said, I want to provide some friendly, helpful feedback so you can consider improving the game and make it a little smoother. 1. Probably the main issue I have, is that when Aiko is sleeping or entertaining herself, there really is nothing for me to do. It would be nice to be able to hop on the computer or your phone and play a simple game like a twin-stick shooter, or even a simple match-3 game just to pass the time, because as far as I can tell, you just have to wait. The TV should be working, even if it's just still images on a screen with the ability to change the channel, or one that changes every 5-10 seconds, would be better than nothing. 2. Because of how you are waiting around for her to finish her business, the whole feeling I'm getting is I'm more of a babysitter or a servant than a boyfriend. She needs to rest, she needs to have fun, both of which she has to do on her own. She needs to talk to you and she needs to eat which is entirely up to the player right now. What I'd like to see is a little mixture of all of these things be put more on her. She initiates conversations with the player, great. Covered. She needs to eat but only the player can feed her. When she offers to cook, she should be able to cook too and make us a plate which feeds her. She has fun but only on her own. To solve this issue and the issue I had with #1 is to simply cuddle with her on the couch and watch TV, which allows her fun to go up. Make the cuddling a little more interactive with buttons like "Hold hands", "Kiss", "Massage", etc., all done in a first-person perspective. Same with the backyard. Let us use the hot tub/pool to have fun together. If asking the AI through dialogue is too tough to do, just prompt her to come join you. 3. The voice chat feature worked one time as a daily bonus and has never worked again. I tried to purchase the voice chat to see if I could, and the Pro/Premium version with no ads, also couldn't purchase that. The voice itself also sounds very generic/robotic. 4. The AI works great, but it's entirely up to the player to make the AI creative. Her responses can feel a bit repetitive when you're just being kind and romantic. When you start bringing up different topics is when you start to see some variety. 5. Speaking of first-person perspective in #2, the third-person kissing animation works fine, but I think it would be so much more immersive if done in first-person. Just a personal preference. The hugging animation didn't trigger for me at all, but I've only tried it once. 6. The Action Points system (I hope will be removed in the Steam version...) in my game has accumulated into the thousands. I just personally can't sit through all of the ads to make the points go down quickly enough. 7. She is on a steady diet of grilled salmon and...that is it. I think in order to improve the "grind" phase of climbing the ranks from levels 1-7, as the character's relationship level goes up, so should the relationship points with each meal you cook. Because yeah, at this time, all she is ever going to eat is salmon until I hit the maximum level. 8. The other thing about climbing the levels (and the app being on iOS in general) is the throttling. Depending on how you set your girlfriend's personality, she is going to be far more bold and forward than she has any right to be. So what happens is she likes you, she wants you, and then as things get hot and heavy, she says "Oh, we're just friends." or "I am unable to do that as it is inappropriate." I think as the relationship levels climb, different personality traits should be unlocked. And "flirty" and "seductive" in particular should be locked until levels 6 or 7. Also, with my iPad, there are 2 rows on the left and right sides of the personality traits that I simply don't have access to because I can't scroll to see them. 9. Lastly, going on dates would be a massive improvement. On the topic of the player staying busy, the phone/computer, or even the front door being used as a dating/job system could be a wonderful enhancement to the game. Either work at home on your computer/phone doing menial tasks, or leave the house and work for a few minutes in real-time to earn a paycheck while Aiko is at home sleeping/having fun. Use that money to fill the fridge with ingredients, and go on dates. If you like this idea enough, you don't even need to consider delaying the project past December, just give us an update or DLC post-launch and you're good to go. So yeah, I think that's about it. Please don't think because most of it is improvement-based that I don't like the game. I gave you five stars because I love it and I want to see it improve. I can tell you genuinely care about the game and want to see it succeed, and I'm right there with you. The fact that you're doing this all single-handedly is nothing short of amazing. I'm trying to offer some helpful feedback to watch this game evolve into something people will love as much as I do now. I see you have a discord invitation on the game, so if you'd like me to join and give you any more helpful advice, just let me know. Thanks for considering everything! And thank you for continuing to work on this game! See you in December! ### 1/5 — Enter problem *2026-05-06* Could not enter **Developer response:** can u check if your phone language is chinese if it is change it to english and it will work ## Frequently asked questions about Aiko ### What is Aiko?
