For even deeper immersion into AI-powered roleplaying, you can use lorebooks, multiple custom user personas, write your own system prompts, create character cards in V2 specification as PNG images, and much, much more. And all of this is already waiting for you in Soul of Waifu!

Soul of Waifu offers a beautiful, intuitive desktop interface with a clean sidebar navigation and responsive design. Everything is in one place: your characters, models, settings, and tools. Whether you're creating a new character or managing your local LLMs, the process is smooth, organized, and user-friendly - no need to juggle multiple applications or complex setups.
Immerse yourself in AI-powered roleplaying with characters that feel alive. Soul of Waifu brings together chat, voice, avatars, high-quality memory, and emotion in a single, seamless experience. Start a conversation, call your character, hear their voice, see their emotions change in real-time - all without leaving the app.
Create rich, dynamic characters with full control over their personality, backstory, and behavior. Import or export character cards in v2 spec (PNG), set custom greetings, define world lore, and fine-tune their responses. You can even assign specific personas to yourself, shaping how the AI perceives and interacts with you.
Soul of Waifu gives you the freedom to connect to a wide range of AI providers. Seamlessly switch between different backends depending on your needs, privacy preferences, and performance requirements. There are several provider to choose from: Character AI, Mistral AI, Open AI and OpenAI-compatible APIs, OpenRouter. This flexibility ensures you're never locked into a single provider. You can experiment with different models, compare responses, and find the perfect fit for each character.
No more manual model hunting or complex setups. Soul of Waifu integrates with Hugging Face, letting you search, preview, and download local language models (GGUF format) directly within the app. Powered by Llama CPP, it supports GPU acceleration (CUDA/Vulkan), memory locking (MLock), and Flash Attention - all configurable with a few clicks.
Make your characters truly come alive. Choose from images, Live2D or VRM 3D models that react with 28 different emotions based on the conversation. Use advanced Text-to-Speech engines like Kokoro 82M, ElevenLabs, XTTSv2, or Edge TTS with support for Russian, English, Japanese, and Chinese voices. You can also use RVC models to change your character's voice. Enable Speech-to-Text (Vosk, Whisper) to talk to your character in real-time with Soul of Waifu System module.
Go beyond basic prompts. Use Lorebooks to inject world knowledge via keyword triggers, write custom System Prompts with full control over context order, and manage multiple User Personas for different scenarios. Enable Smart Memory to keep context relevant and efficient — only the most important messages are included in the prompt.
Take your interactions to the next level with the Soul of Waifu System - a powerful module that enables real-time, speech-to-speech communication with your AI character. Talk naturally using your microphone, hear your character respond instantly in their unique voice, enjoy fully immersive calls where the character’s Live2D/VRM avatar reacts with emotions and animations.
Your conversations stay on your machine. When using local language models, no data leaves your computer. Even with API-based services, your interactions remain confidential. You’re in full control - no corporate surveillance, no data harvesting, no censorship. Your waifu and your rules.
