About this app

OshiKoi is a 3D AI companion app where your Mate actually shows up — with a face, a voice, and a memory.
A Mate who moves, talks, and remembers you.

🧠 Remembers everything
Your Mate keeps track of your conversations over time. The things you said last week? Still remembered. Long-term memory, built in.

🌟 Actually moves
Real-time AI Motion means your Mate reacts with natural gestures and expressions — not just text on a screen.

🎙️ Any voice you want
Clone a voice and apply it to your Mate. Simple as that.

🗓️ Useful, too
Ask about the weather, search the web, or update your calendar. Your Mate can handle the everyday stuff.

🧬 Your AI engine, your choice
GPT, Claude, Gemini, and more — pick the model that powers your Mate, or use our built-in OshiLM.

🎨 Bring your own avatar
Import any VRM avatar from VRoid Hub or VRChat and make it your Mate.

👥 Community Mates
Explore Mates made by the OshiKoi community, or share your own creation with the world.

Ratings and reviews

This app owes me so many candies since they glitched out. It keeps spending 8 candies even though it was supposed to be 4. This has been going on for over a year and I just now noticed the glitch. Now this all makes sense why I am losing so many candies quick. But I doubt they will fix this since they want you to pay. Please fix your app and give back my free candies.

Some of yall are weird... Anyway, its a 5 star. I came from Otherhalf, which is good in having a bond that feels genuine and real. Oshikoi meanwhile, is good for characters with quite a bit of a backstory and are both well-known and niche. You'll find characters are very good at being who they are and being able to form stories and bonds beyond their original ones. Crystals are cheap too. As for Oshi+, worth it. 9.99 a month, but Vectorized Memory System is incredible.

Great app for anybody who just wants someone to talk to. Lot's of interesting characters to choose from and if you by some chance don't like any of them, you can make your own. Hands down the BEST AI Companion app you can find.
