What is Rev AI
Rev AI provides speech-to-text, translation, alignment, language identification, and speech-understanding APIs alongside Rev’s human transcription service. Its public API pricing is usage based rather than seat based.
Speech-to-text pricing
As of October 17, 2026, new API accounts receive free credits equal to five hours of Reverb ASR. Reverb transcription costs US$0.20 per audio hour for English, while Reverb foreign-language transcription costs US$0.30 per hour across more than 56 languages.
Whisper Large costs US$0.005 per minute for English. Human transcription costs US$1.99 per minute. Usage is rounded to the second with a 15-second minimum. The current public rate card no longer lists the earlier Reverb Turbo or Whisper Fusion offers, so they are not presented as current products.
Additional APIs
Forced alignment and language identification each cost US$0.003 per minute. Translation costs US$0.002 per minute on Standard or US$0.025 on Premium. Sentiment and topic extraction cost US$0.0008 per ten words; summarisation costs US$0.002 per minute on Standard or US$0.025 on Premium.
Enterprise pricing is negotiated for higher volumes and can include custom rate limits and terms, additional evaluation credits, enhanced security, a dedicated account manager, and priority support.
