Our Verdict
Choose AssemblyAI if you need advanced audio intelligence features (entity detection, topic detection, auto chapters, summarization, PII redaction) in a single API, want a $50 free credit for prototyping and testing, or prioritize feature richness and content generation capabilities over the absolute lowest per-minute transcription cost.
Choose Rev AI if you need the lowest possible per-minute cost for high-volume batch transcription (Reverb Turbo at $0.10/hour is 33% cheaper than AssemblyAI), require human transcription fallback at $1.99/min for mission-critical accuracy that automated models cannot match, or only need basic transcription without advanced audio intelligence features.
Frequently Asked Questions
01 Which is cheaper for basic transcription, AssemblyAI or Rev AI?
Rev AI is cheaper for basic transcription. Reverb Turbo costs $0.10/hour ($0.00167/min), which is 33% cheaper than AssemblyAI Universal at $0.15/hour ($0.0025/min). Rev AI's standard Reverb at $0.20/hour is 33% more expensive than AssemblyAI, so the savings depend on choosing the right Rev AI model. For 1,000 hours of monthly transcription, Reverb Turbo costs $100/month vs AssemblyAI's $150/month, saving $600/year. However, AssemblyAI includes a $50 free credit for testing, while Rev AI charges from the first minute.
02 Does Rev AI offer a free tier like AssemblyAI?
No, Rev AI does not offer any free tier, free credits, or trial period. You are charged from the first minute transcribed. AssemblyAI offers a $50 free credit (no credit card required) covering approximately 185 hours of Universal transcription. For developers who need to test before committing, AssemblyAI's free tier is a significant advantage. Rev AI compensates with its ultra-low Reverb Turbo pricing at $0.10/hour, meaning even small-scale testing costs very little.
03 When should I choose Rev AI's human transcription over AssemblyAI's AI models?
Rev AI's human transcription at $1.99/min is ideal for mission-critical content where accuracy must be near-perfect: legal proceedings, medical dictation, published media transcripts, or regulatory filings. AssemblyAI does not offer human transcription at all. However, Rev AI's human rate is 597x more expensive than its Reverb model ($0.00333/min) and 796x more than AssemblyAI Universal ($0.0025/min). Most use cases are better served by AI transcription with manual review rather than full human transcription.
