wit.ai
Free natural language platform from Meta for building conversational interfaces and voice-enabled apps.
Wit.ai, owned by Meta, is a free natural language processing platform that helps developers build applications and devices that understand human language. It turns spoken or written input into structured intents and entities that applications can act on.
Features include intent recognition, entity extraction, trait detection, built-in entities for common concepts like dates and locations, and speech recognition for voice interfaces. Developers train models simply by providing example utterances, and Wit.ai improves automatically as it receives more data.
Wit.ai powers chatbots, voice assistants, home automation, and wearable interfaces. With no usage fees and support for dozens of languages, it is a popular choice for prototyping conversational and voice-driven experiences.
