What is Wit AI?

Wit AI is a natural language processing platform that helps you build applications capable of understanding and responding to human language. Owned by Meta, it provides tools to create chatbots, voice assistants, and other conversational interfaces without requiring deep expertise in machine learning. The platform handles the complex work of training language models, so you can focus on building the user experience. It's suitable for developers of all skill levels, from those building simple chatbots to teams creating more sophisticated voice-controlled applications.
