Isekai Chat: AI Character RPG

CREATE LAB

About this game

Step into an "isekai" world — a serious AI character chat & roleplay app.
Voiced official characters are waiting to talk with you, in character.
On-device speech lets your favorite character actually speak to you out loud.
Long-term memory keeps your names, promises and likes, for a bond that's truly yours.
Collect costume gacha cards and even play a dice-driven TRPG in one deep world.

■ Voiced isekai AI characters
On-device speech synthesis plays each character's voice (supported devices). Get closer through voice, not just text.

■ An AI chat that remembers you
Long-term memory recalls what you talked about, the promises you made and what you love — so your roleplay bond deepens day by day.

■ Costume gacha & card collection
Collect R / SR / SSR costume cards and set your favorite as your chat portrait or avatar.

■ A real TRPG with an AI GM
A genuine TRPG mode where dice rolls branch the story, with a 50-monster codex and an AI Game Master.

■ A world with real depth
The Moonlight Knights, the Starfarer's Guild, the Nightfall Academy and House Soleil — seven official characters await in one interwoven world.

■ Spectate, world events & diary
Watch characters talk to each other, follow a timeline that reacts to world events, and look back on your chats in a diary.

■ Pricing
Free to play, with optional purchases (coins, premium plans) and random-item gacha (odds shown in-app).
