Create or choose a fictional character and chat freely about anything — with built-in memory and emotion that keep every conversation continuous and natural.
Our AI chat service lets you create or choose fictional characters that users can talk to naturally — on your website, app, or LINE OA. Each character has its own personality, voice, and backstory, and can hold open-ended conversations across any topic instead of following a rigid script.
Under the hood, a memory and emotion system keeps every conversation continuous and in-character: the assistant remembers what was said before, adapts its mood to the user, and stays consistent over time. The result is a companion that feels alive and keeps users coming back.
4 core capabilities, built and tuned for your business.
Create your own fictional character from scratch or pick one from a ready-made library, then shape its look, voice, and personality until it fits your brand or story. Every detail — from backstory to speaking style — is yours to define.
The assistant holds open-ended conversations on any topic instead of following a fixed decision tree, so users can talk about whatever they like and still get a natural reply. It keeps context across turns so the chat never feels disjointed.
Each character remembers past conversations, user preferences, and important details, so it stays consistent from one session to the next. Returning users are recognized and the relationship picks up where it left off.
Replies carry emotion and mood that match the moment, so conversations feel warm and human rather than robotic. The character's personality stays steady while its tone adapts to how the user is feeling.
