Langding is an AI-driven landing page auto-translation tool designed for developers who need to localize their websites efficiently. It extracts meaningful content from HTML files, translates it using advanced AI models (OpenAI GPT or Anthropic Claude), and generates complete multilingual versions with automatic language detection.
