AI分身术 helps you create, configure, and use AI avatars and AI assistants for real work. Build an assistant around a role, connect it with knowledge bases, files, images, and tools, then chat with it to analyze information, draft content, organize ideas, and keep useful context available. What you can do: - Chat with different AI assistants using text, images, and voice. - Connect documents and knowledge bases so answers can use your own context. - Create task-focused assistants for learning, research, writing, content creation, and everyday work. - Use tools for web research, image generation, presentations, pages, and structured data. - Manage knowledge, data, and access in team or enterprise scenarios. AI分身术 is designed to help people turn expertise into reusable AI workflows. It supports personal productivity, knowledge management, creative work, and team collaboration. AI can make mistakes. Review important outputs before relying on them.
