Sonix and Rev are both US-based cloud transcription services with speaker diarization, but they differ on pricing model, API depth, human-review options and built-in analysis. Sonix uses pay-as-you-go at $10/hr plus Premium and Enterprise subscriptions (Sonix pricing page), covers 53 languages, and bundles sentiment analysis, topic detection and entity recognition. Rev leans on a cheap async API at $0.003/min (its Reverb model, ~5% WER, Rev pricing) across 58 languages, adds seat plans from ~$25/mo, and offers optional 99%+ human transcription at $1.99/min; Sonix has no human-review tier.
Choose Sonix if you want built-in AI analysis (sentiment, topics, entities) and a per-hour model tied to an editing workspace. Choose Rev if you want the lowest per-minute automated cost via a developer API and SDK, an optional human-transcription tier, or SOC2/HIPAA on the cloud side; Sonix lists SOC2 and GDPR.
