Heavily inspired by Neuro-sama

Warning

Attention: We do not have any officially minted cryptocurrency or token associated with this project. Please check the information and proceed with caution.

Note

We've got a whole dedicated organization @proj-airi for all the sub-projects born from Project Moeka. Check it out!

RAG, memory system, embedded database, icons, Live2D utilities, and more!

Tip

We have a translation project on Crowdin. If you find any inaccurate translations, feel free to contribute improvements there.

Have you dreamed about having a cyber living being (cyber waifu, digital pet) or digital companion that could play with and talk to you?

With the power of modern large language models like ChatGPT and famous Claude, asking a virtual being to roleplay and chat with us is already easy enough for everyone. Platforms like Character.ai (a.k.a. c.ai) and JanitorAI as well as local playgrounds like SillyTavern are already good-enough solutions for a chat based or visual adventure game like experience.

But, what about the abilities to play games? And see what you are coding at? Chatting while playing games, watching videos, and is capable of doing many other things.

Perhaps you know Neuro-sama already. She is currently the best virtual streamer capable of playing games, chatting, and interacting with you and the participants. Some also call this kind of being "digital human." Sadly, as it's not open sourced, you cannot interact with her after her live streams go offline.

Therefore, this project, Moeka, offers another possibility here: let you own your digital life, cyber living, easily, anywhere, anytime.

What's So Special About This Project?

Unlike the other AI driven VTuber open source projects, Moeka was built with support of many Web technologies such as WebGPU, WebAudio, Web Workers, WebAssembly, WebSocket, etc. from the first day.

Tip

Worrying about the performance drop since we are using Web related technologies?

Moeka runs in the browser, and it stays partially powered by Web technologies for graphics, layouts, animations, and the WIP plugin system for everyone to integrate things.

This means that Moeka is capable of running on modern browsers and devices and even on mobile devices (already done with PWA support). This brings a lot of possibilities for us (the developers) to build and extend the power of Moeka VTuber to the next level, while still leaving the flexibility for users to enable features that require TCP connections or other non-Web technologies such as connecting to a Discord voice channel or playing Minecraft and Factorio with friends.

Note

We are still in the early stage of development where we are seeking out talented developers to join us and help us to make Moeka a reality.

It's ok if you are not familiar with Vue.js, TypeScript, and devtools required for this project, you can join us as an artist, designer, or even help us to launch our first live stream.

Even if you are a big fan of React, Svelte or even Solid, we welcome you. You can open a sub-directory to add features that you want to see in Moeka, or would like to experiment with.

Fields (and related projects) that we are looking for:

• Live2D modeller
• VRM modeller
• VRChat avatar designer
• Computer Vision
• Reinforcement Learning
• Speech Recognition
• Speech Synthesis
• ONNX Runtime
• Transformers.js
• vLLM
• WebGPU
• Three.js
• WebXR (checkout the another project we have under the @moeru-ai organization)

If you are interested, why not introduce yourself here? Would like to join part of us to build Moeka?
