About Rev AI

Rev AI is the developer API platform of Rev, an Austin-based transcription company founded in 2010 with $51.5M in Series B funding. The platform provides speech-to-text APIs combining automated AI transcription via its Reverb model with an optional pathway to professional human transcriptionists, giving teams a single vendor for both speed and maximum accuracy use cases. Reverb, the core AI model, is trained on over 3 million hours of human-transcribed audio and processes audio in both batch (asynchronous) and real-time (streaming) modes. Speaker diarization is included by default on all asynchronous requests, identifying and labeling up to 8 distinct speakers without additional configuration or cost. The API supports 58+ languages for basic transcription. Advanced intelligence features like sentiment analysis and topic extraction are currently English-only but available as paid add-ons. Rev AI is best suited for English-language teams in media, legal technology, and compliance who need reliable batch transcription at low cost, plus the option to route difficult audio to human transcriptionists on the same platform without vendor switching. Podcast publishers, legal tech developers building deposition tools, and content compliance teams benefit from the hybrid AI-plus-human workflow. Pricing includes a free tier with 45 AI minutes per month, subscription plans starting at $25.49/seat/month (Essentials with 5,000 minutes), and pure API pay-as-you-go at $0.003 per minute for the Reverb model with no monthly minimum. Human transcription is available at $1.99 per minute for 99%+ accuracy. Enterprise plans include custom pricing, dedicated SLAs, and HIPAA-compliant processing. Rev AI released Reverb and its speaker diarization models as open-source in 2024, allowing teams to self-host for free and reducing vendor lock-in compared to closed-source competitors like Deepgram and AssemblyAI.

Pricing

Free: 45 AI mins/month (English only). Essentials: $25.49/seat/month annual ($29.99 monthly), 5,000 AI mins. Pro: $47.99/seat/month annual ($59.99 monthly), 10,000 AI mins, 37+ languages. Pay-As-You-Go API: $0.003/min Reverb model. Human transcription: $1.99/min for 99%+ accuracy. Enterprise: custom pricing with HIPAA mode and SLA.

Key Features

• Reverb AI Model: Trained on 3 million+ hours of human-transcribed audio, delivering low word error rates across 58+ languages at $0.003/minute with no monthly minimum on pay-as-you-go.
• Default Speaker Diarization: Identifies and labels up to 8 speakers on all asynchronous requests by default, achieving 95% diarization accuracy without additional configuration or cost.
• Hybrid AI and Human Workflow: Route difficult audio to Rev's professional transcriptionists at $1.99/minute for 99%+ accuracy via the same API, eliminating vendor switching and integration rebuilds.
• Audio Intelligence Add-ons: Sentiment analysis, topic extraction, and language identification available as paid modules for English audio, layered on top of base transcription in a single request.
• Open-Source Reverb Model: Reverb and speaker diarization models released as open-source in 2024, enabling free self-hosting and reducing vendor lock-in versus Deepgram and AssemblyAI.

Pros

• Reverb model at $0.003/min is 5-6x cheaper than Deepgram Nova-3 ($0.0077/min) for English batch transcription with comparable accuracy on clean audio.
• Speaker diarization included by default at no extra cost with 95% accuracy, versus Deepgram and AssemblyAI charging add-on fees for diarization features.
• Hybrid AI-plus-human workflow on one platform lets teams escalate critical audio to transcriptionists at $1.99/min without switching providers, unique among API-first STT vendors.

Cons

• Sentiment analysis, topic extraction, and advanced intelligence are English-only, blocking multilingual enterprise deployments from accessing these features.
• Accuracy on noisy recordings drops to 70-75%, making it unsuitable for call center and telephony audio without manual review or human transcription escalation.
• SDKs limited to Python, Node.js, and Java — no Go or .NET support — reducing adoption among teams in those language ecosystems.
