Soul of Waifu enables users to interact with AI-driven characters through text and voice, offering emotional depth and customizable avatars. It targets AI enthusiasts and fans of character-based interaction, providing an immersive experience without requiring deep technical knowledge.

How It Works

The application leverages multiple Large Language Models (LLMs) for conversational AI, including Character AI, Mistral AI, OpenRouter, OpenAI, and local LLMs. It integrates Speech-to-Text and Text-to-Speech (TTS) capabilities using various engines like Character AI's proprietary voices, ElevenLabs, XTTSv2, and Edge TTS, with support for RVC voice cloning. Characters can be represented by static images with emotion kits or dynamic Live2D models.
