An open-source Figma design system for rich LLM conversational interfaces
A large library of ready-made building blocks for conversational interfaces, plus screens you can customise to match your product.
Chat bubbles, sidebars with adjustable settings, prompt boxes and dedicated multi-prompt workflow screens cover the core chat patterns.
Override colors, spacing and typography through Figma variables and styles to match a brand system without rebuilding components.
A pre-designed dark theme is included, so you do not have to rework every screen for dark mode.
Describe your idea in chat and Lovable turns it into a working app or website
Describe features in everyday language and the builder creates or edits the UI, logic, and structure of a full-stack web app.
Generate front ends, backend functions, and database-backed features rather than static mockups, so the result can actually run.
Ship your project to a shareable live URL, then point a custom domain at it when you are ready to launch.
Wire the app to external APIs and services, and add AI-powered functionality such as chat, search, or generation directly inside your product.
