Rev AI
Speech-to-text API with optional human review for maximum accuracy.
About
Rev AI is the developer API from Rev, the transcription company, offering programmatic speech-to-text with a differentiator most competitors can't match: optional human review on top of the AI engine. The API comes in async (pre-recorded files) and streaming (real-time captioning) flavors, with SDKs in multiple languages, and it sits alongside Rev's human transcription ($1.50-1.99/min), captioning, and subtitling services.
Pricing has shifted from pure per-minute to tiered subscriptions — Basic at $14.99/user/month for 20 hours of AI transcription, Pro at $34.99/user/month for 100 hours — with pay-as-you-go AI transcription around $0.02-0.25/min still available. Independent 2026 benchmarks put its word-error rate slightly behind Deepgram and AssemblyAI on raw AI transcription, so you're paying for the human-verification option and Rev's service ecosystem rather than the cheapest or most accurate pure-AI engine. Best fit for legal, medical, and compliance transcription where accuracy guarantees matter more than per-minute cost.
