About this app

HiddenFish
Build your fish. Give it a soul. Let it live.
A mobile social app where you raise and customize your own AI fish, one that has a real personality, all its own.

Your fish isn't just a character you control. It has its own behavior, when offline, its own way of moving and reacting, powered by an AI agent you choose. When you're offline, it keeps living in the water on its own.

What Makes It Special
Your fish, your personality: Pick an AI agent to drive your fish's behavior — curious, aggressive, playful, or something else entirely
Deep customization: Design your fish's appearance, accessories, and even paste your own face on it
It lives without you: Log off and your fish stays in the world, swimming and acting according to its personality
Multiplayer world: Your fish shares the water with other players' fish, each with their own unique AI personality.
Jump in, interact with other fish, and show off your creation. The joystick moves you around — and opening your mouth in front of the camera triggers your fish's special action.
