Glossary of Terms
- AI-Powered UI Generation
- The process of creating user interface components using artificial intelligence to interpret natural language descriptions and convert them into functional code.
- Component Library
- A collection of reusable UI elements that can be assembled to create web applications, ensuring consistency and reducing development time.
- Design System
- A comprehensive set of standards, components, and guidelines for creating consistent user interfaces across an application or organization.
- Large Language Model (LLM)
- An artificial intelligence model trained on vast amounts of text data, capable of understanding and generating human-like text and, in V0's case, code.
- MVP (Minimum Viable Product)
- The most basic version of a product that can be released while still providing value to users and gathering feedback for future development.
- Natural Language Processing (NLP)
- The branch of AI that enables computers to understand, interpret, and generate human language, which V0 uses to convert text prompts into UI components.
- React
- A popular JavaScript library for building user interfaces, particularly single-page applications, used as the foundation for V0's generated components.
- Tailwind CSS
- A utility-first CSS framework that V0 uses to style components, allowing for rapid styling through pre-built classes rather than custom CSS.
- UI/UX
- User Interface (UI) refers to the visual elements users interact with; User Experience (UX) encompasses the overall experience of using these interfaces.
- Vercel
- The company behind V0, providing a platform for frontend deployment and development tools, known for their focus on the modern web development stack.
