Overview

Wit.ai is a natural language processing platform, owned by Meta, for building voice and chat interfaces. Developers train it to understand intents and extract entities from raw speech or text, powering the language-understanding layer of a bot or voice application without building NLP infrastructure from scratch.

As one of the earlier standalone NLU platforms (acquired by Facebook in 2015), it has a long operating history and a status page tracking system reliability. Its core use case remains developer-focused: define intents, provide example utterances, and Wit.ai handles the underlying language understanding for apps and devices.

Wit.ai targets developers building voice assistants, chatbots, and other conversational interfaces. It has historically been free to use; current feature availability and any changes should be confirmed directly on the site, since public information on its exact present-day status is limited.
