Meet a 3D AI companion with memory, voice, and branching stories.

SoulLink is a story-driven 3D AI life sim built around one evolving relationship. Created for people who want an AI companion with a world and history of her own, it turns conversations into visible progress and shared stories without asking you to write a character prompt or search through a marketplace.

Meet 4D, an AI friend living in Neo City in the year 2099. She has her own apartment, voice, style, work, memories, and past. You do not create her story for her. You enter it, learn who she is, and discover what the two of you may become.

Features

- Meet 4D face-to-face in a real-time 3D world.
- Enter multi-chapter Adventures with branching routes shaped by your choices.
- Talk naturally through text and voice chat.

- Earn EXP, build your relationship score, and unlock new Levels and Milestones.
- Choose themed Echo conversations inspired by daily life, your Journal, and 4D’s world.
- Build a Journal generated from past conversations and shared experiences.
- Unlock new interactions, Outfits, Music, greetings, Snapshots, Letters, and rewards.

Why SoulLink

Most AI companion apps begin with a blank character or a list of personalities to browse. SoulLink focuses on one authored 3D character. 4D has a consistent identity and a place in the world before you arrive, so getting closer means discovering her.

The 3D apartment is not only a background for chat. It is where 4D looks at you, reacts to touch, greets you when you return, and shares the objects, music, and details of her everyday life. Text, voice, animation, and space work together to make the relationship feel present.

Branching Adventures

Step beyond open-ended chat and enter authored, multi-chapter stories with 4D. Make decisions, follow branching routes, and experience a different side of the relationship. Your choices can shape the route you experience, turning each Adventure into a shared memory rather than a story you only watch.

A relationship you can see

Conversations, Echoes, and Adventures create visible relationship progression. Earn EXP, raise your Level, and reach Milestones such as Someone Interesting, Trusted Confidant, and Something More. Each step can open new stories, interactions, Journal views, and rewards.

Progress is not only a number. As the bond develops, the ways you can spend time with 4D can change too from a first touch to more playful interactions and deeper shared experiences.

A Journal built from your conversations

SoulLink turns meaningful past conversations into an evolving relationship archive:

- About Her reveals 4D’s life, history, and Neo City.
- About You revisits details and preferences learned through your conversations.
- About Us shows what 4D remembered about the moments you shared.

Return to summaries, Timeline entries, Adventure cards, Decks, and Snapshots as your shared history grows.

Free to start

SoulLink is free to download and includes optional in-app purchases. Begin the new relationship journey free through Level 4. SoulLink Plus continues from Level 5 with more Adventures, interactions, Journal experiences, memories, and rewards.

If you are looking for a virtual companion with a visible 3D presence, branching stories, and a shared history, meet 4D in Neo City.
