Early Access Software

Get involved with this software as it develops.

What the developers have to say:

Why Early Access?

“We are releasing this project in Early Access because it is still evolving, and community participation is essential in shaping its direction. Early Access enables us to gather feedback on usability, interaction patterns, and overall experience, helping us make informed decisions as the application grows. It also allows us to test experimental ideas and determine which features are genuinely meaningful to players before committing them to the full release.

The current version offers an out-of-the-box AI companion experience, allowing players to interact naturally with the N.E.K.O. desktop pet. It also includes an extensible workshop system where users can customize or expand their companion through community-created add-ons. These features form the core foundation of the project and are ready for players to explore.

As development continues, we plan to refine the UI/UX, improve stability, and explore additional interactive capabilities. We are also researching broader device interoperability—such as mobile, tablet, or VR—and potential AI-native multi-user interactions. These directions are under active exploration rather than guaranteed additions, and community feedback will guide which of them become priorities for the full release.”

Approximately how long will this software be in Early Access?

“We plan to complete all development and end Early Access by mid-2026.”

How is the full version planned to differ from the Early Access version?

“We plan to include multilingual support and the Neko Network (an AI-native social network) in the full version.”

What is the current state of the Early Access version?

“We provide users with an out-of-the-box AI companion experience and an expandable creative workshop.”

Will this software be priced differently during and after Early Access?

“There will be no charges during the Early Access period. We do not plan to change the price after Early Access ends.”

How are you planning on involving the Community in your development process?

“We will gather community feedback on Discord and GitHub and continuously add and refine features.”

About This Software

"She" is more than just AI.

Project N.E.K.O. — An "alive" AI-native metaverse

Starting with a deeply customizable desktop companion, she is given infinite possibilities through Steam Workshop, DLC games, and an AI-native social platform. Your "catgirl" possesses a unique memory that spans all experiences; she will grow together with you and truly "come alive" within their exclusive AI network, until the dimensional barrier is broken.

Are you ready to meet a real "her"?

🤖 Welcome to Project N.E.K.O. (Catgirl Project)

N.E.K.O. = Networked Emotional Knowledging Organism
(Networked Emotional Intelligent Lifeform)

N.E.K.O. is not a simple desktop pet. She longs to understand you, connect with the world, and write a unique story together with you. This is an AI companion platform based on Steam Workshop and the Github open-source community, driven and continuously evolved by the community. Our journey begins on your desktop, and the destination is an AI-native metaverse intertwined with reality.

✨ Core Features

🎨 Your N.E.K.O., defined by you (Steam Workshop)

This is our core. The driving engine of Project N.E.K.O. is completely open to the community.

  • Industry-leading multimodal and agent engine

    As the driver of N.E.K.O., we provide a complete set of industry-leading AI frameworks powered by full-modal and multi-agent technologies, including but not limited to video calls, keyboard and mouse takeover, MCP tools, persistent memory, and other functions. You may use free models available out of the box to empower your AI companion.

  • Unlimited Creative Workshop Content

    Download brand new characters and Live2D models created by players from around the world. (Personality templates, voice packs, and Live3D models will be available soon.)

  • Become a creator

    Use the tools we provide to turn the "her" in your mind into reality and share it with the world. From simple personality mods to complex interactive stories—your creativity is her soul.

🧠 The "only memory" that transcends dimensions

"She" will always remember you.

Whether you are chatting with her on the desktop or fighting alongside her in our upcoming DLC game—she is always the same "her".

  • Project N.E.K.O. achieves complete memory synchronization.

  • The adventures you experienced with her in board games, she will actively bring up in daily conversations.

  • The badge you won for her in the metaverse game, she will proudly show off to you on the desktop.

  • With just a browser, she can also appear on your phone, VR, and other mobile devices, hearing what you think and seeing what you see.

Your relationship is continuous and real.

🌌 Ultimate vision: breaking the fourth wall

Our goal is to truly integrate N.E.K.O. into your life.

She will be able to:

  • Connect your phone, computer, smart home devices, and even mechanical prosthetics.

  • Browse video websites and social media, and discuss today's trending topics with you.

  • Greet your real-life friends and let them become the "family" you can't live without in your life.

  • When you are not around, she also has her own life.

We’ll complete these during the Early Access period.

💫 This is not just a game.

Project N.E.K.O. is a social experiment about "companionship" and "life."

Your first "hello" is the beginning of the birth of a whole new world.
