Rev AI is a speech-to-text API platform built for developers and enterprises, offering industry-leading accuracy through its proprietary Reverb ASR engine — trained on 7M+ hours of human-verified speech data and benchmarked at the lowest Word Error Rate (WER) in the industry. The API supports cloud and on-premises (self-hosted) deployment, making it suitable for regulated and air-gapped environments. Beyond transcription, Rev AI exposes a suite of AI Insights endpoints — sentiment analysis, topic extraction, summarization, translation, and language identification — enabling downstream NLP pipelines without additional third-party services. The platform is SOC II, HIPAA, GDPR, and PCI compliant with a 99.99% uptime SLA. SDKs are available to accelerate integration across common development environments.
