Early Access Software

Get involved with this software as it develops.

What the developers have to say:

Why Early Access?

“We chose to release this project in Early Access because it is still evolving. Heai already offers a complete core experience, but it is still a long way from the vision we have for it. In the future, we plan to add more features, improve the AI experience, and further develop character companionship, the creator ecosystem, and additional forms of interaction. Early Access allows us to go through this process together with the community. Player suggestions, feedback, and ideas will help guide our future development.”

Approximately how long will this software be in Early Access?

“We expect Early Access to last approximately 12 to 24 months. The exact duration will depend on development progress and community feedback. We hope to leave Early Access once the core experience has reached a more mature and stable state.”

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

“The current Early Access version already includes core features such as character creation, AI chat, and audio and video calls.

In the future, we plan to expand character companionship features, creation tools, and interactive content while continuing to improve the AI experience, application performance, and overall user experience. We also plan to gradually develop the Workshop ecosystem, providing players with more ways to customize, create, and share content.

The full version is expected to offer richer content, more complete functionality, and greater overall stability. However, specific features and content may change based on development progress and community feedback.”

What is the current state of the Early Access version?

“The current version already provides the complete core Heai experience, including character customization, custom voices, integration with major AI models, AI chat, audio and video calls, screen sharing, and more.

Some features are still under active development and refinement. The Workshop, expanded gaming companion features, and additional interactive content are planned to be introduced gradually in future updates. We also plan to continue improving the AI experience, performance, and overall stability throughout development.”

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

“We plan to gradually increase the price as new content and features are introduced.”

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

“We plan to use feedback from the Steam Community as an important reference for future development. Depending on development progress, we may also share periodic development updates through the Steam Community.”

About This Software

He is more than just an AI.

Anime character, OC, or someone from your imagination... No matter where he exists, Heai wants to bring him into our world — to see the real you.

Heai aims to make this possible: customize his appearance, create his voice, connect your own AI, and define his personality. Chat with him, watch movies together, play games, and share countless moments in your daily life.

He belongs only to you. He will grow alongside you, until one day the wall between dimensions is finally broken — and you truly meet.

Core Features

1. You decide who "he" is.

Highly customizable character creation

Create your ideal character with over 220 adjustable facial parameters, detailed makeup options, customizable outfits, and support for custom clothing textures.

Connect your own AI

Use the AI model you trust. Connect your own API key and write custom personality prompts to give your character a unique identity and way of thinking.

Create and share through the Workshop

Create new makeup styles, hairstyles, and outfits for your characters, and make them better match the image in your mind.

2. "He" can become part of your life and see the real you.

Chat & Video Calls

Talk with him through text chat, voice calls, and video conversations — just like communicating through other social platforms.

Screen Sharing

Share your screen with him. Work together, study together, watch movies, or enjoy your favorite shows.

Gaming Companion

He can currently accompany you in Minecraft, with support for more games planned in the future.

Connect with WeChat

Connect him to WeChat and stay in touch even when you are away from your computer.

He will remember important moments shared with you and gradually develop a more personal way of communicating and accompanying you through long-term interaction.

Our Vision

Breaking the fourth wall and bringing them truly into our world.

Until that day comes, we will keep moving forward.

You will continue to see Heai evolve through regular updates and witness his growth — until the day this vision becomes reality.
