BSide: Olivia Lin: HoYoverse's New AI-Powered Music App Is Not a Game
What happens when a studio known for massive anime RPGs like Genshin Impact and Honkai: Star Rail releases a desktop utility? BSide: Olivia Lin is exactly that—a music curation tool powered by artificial intelligence, now listed on Steam. It's not another open-world adventure. Instead, it's a bold step into AI-driven interactive media, launching under Steam's “Application” and “Utilities” categories.
Quick Facts: What You Need to Know

HoYoverse, the global gaming giant behind some of the most profitable mobile and PC titles ever, has taken a sharp turn. Instead of another action RPG, they're testing a desktop application that blends music composition, virtual companionship, and generative AI. Based on our first look at the Steam listing, this is a clear move to gather real-time data on video rendering and conversational AI loops.
Meet Olivia Lin: A Virtual Pianist with AI Letters
The star of the show is Lin Li, also known as Olivia Lin. She's a Shanghai university student studying piano (with a minor in psychology). Users interact with her through three main features: listening to her piano performances, exchanging AI-generated letters, and using a live desktop wallpaper engine. This is not a game. There's no combat, no gacha system, and no open world to explore.
The heart of the experience is the interactive music tool. BSide: Olivia Lin allows anyone to upload their own MIDI files. The app then automatically turns those files into fully animated music videos. This feature alone makes it a unique creative tool for musicians and hobbyists.
AI Chat and Live Wallpaper
Beyond the music, the app includes a dynamic wallpaper system. Your desktop comes alive with Olivia's world. And the letter system? It's built on a conversational AI. You write to Olivia, and she writes back, generating text responses based on her programmed personality. It's a curious mix of utility and emotional design.
Why a Game Studio Made a Desktop Utility
HoYoverse isn't just experimenting for fun. This project is a tech testbed for their larger AI ambitions. They recently announced a massive three-year investment into full-stack AI development. BSide: Olivia Lin gives them real-world performance data on video rendering speed and how users interact with AI chat loops.
This is a smart move. Instead of waiting for a finished product, they launch an Early Access tool and learn from millions of users. From what we've seen, this approach mirrors how other tech giants beta-test AI features. It's cheaper, faster, and provides more accurate feedback than internal testing alone.
How It Stacks Up Against Competitors
Compared to other AI music tools like Google's MusicLM or Meta's MusicGen, BSide: Olivia Lin is more focused on personal interaction. Those other tools are purely functional—generate a track, export it, done. HoYoverse's app adds a narrative layer. You're not just making music; you're building a relationship with a virtual character.
This blend of utility and storytelling is where HoYoverse excels. Their previous games proved they can craft characters players love. Now they're applying that same skill to a desktop utility. It's a unique approach that no major competitor has tried.
The Future of Interactive Media
Will BSide: Olivia Lin become a hit like Genshin Impact? Probably not. But it doesn't need to. This app is a stepping stone. It gathers data on how people interact with AI-generated content, video rendering pipelines, and responsive chat systems. That data could shape HoYoverse's next major game launch or even a standalone AI product.
For now, the app is free on Steam, and anyone with a PC can try it. It's a strange, quiet experiment from a studio famous for explosive action. But sometimes, the most important innovations are the quiet ones.
