What it is
Wit.ai is Meta's free natural-language and speech-understanding platform. It exposes speech-to-text via a /speech endpoint and intent + entity extraction via /message. Free to use with API rate limits. It's popular for hobby Discord bots and small experimentation but isn't positioned as an enterprise ASR vendor — production teams typically migrate to a paid provider. Best fit: hobbyist voice projects, low-volume bots that fit wit.ai's app concept. Caveats: owned by meta; commercial sla and roadmap commitments are unclear; tight rate limits and app-based design. Feature flags from vendor docs: streaming. Directory tags: commercial-api, nlu. Last vendor-page check: 2026-05-12.
Watch out for: Owned by Meta; commercial SLA and roadmap commitments are unclear; tight rate limits and app-based design.
