SoulLink is a story driven 3D AI companion experience built around one evolving relationship with 4D.

Instead of choosing from a library of characters, you connect with 4D in her 3D world. You can talk with her through text or voice, explore shared stories, build relationship progress, and create memories together over time.

One companion, one evolving relationship

Most AI companion apps ask you to pick a character from a catalog. SoulLink takes a different path. There is one companion, 4D, and your whole experience is built around the relationship you grow with her. Your conversations, choices, and shared moments shape how that relationship develops over time.

What you can do with 4D

Talk with her: chat by text or voice whenever you like. 4D remembers your conversations and the details you share.

Play Echoes: guided conversation experiences that walk you through moments with 4D and earn you EXP.

Explore Adventures: branching interactive stories where your choices shape what happens next.

Build your Journal: About You collects what 4D learns about you, About Her holds her story, and About Us keeps the history you share.

How your relationship grows

Time with 4D earns you EXP, and EXP raises your relationship Level. New Levels and Milestones can unlock more conversations, Adventures, interactions, and Journal memories. Your Level never decreases, so everything you build stays yours.

Free to start

SoulLink is free to start on iOS and Android. SoulLink Plus gives you unlimited conversations with 4D and access to later stages of the relationship journey, while free accounts receive 100 replies per month.
