Description
Rev is a transcription and captioning platform offering both AI and human transcription from the same account. The AI tier transcribes audio and generates captions automatically, while the human transcription service routes a file to Rev’s freelance transcriptionist network for higher accuracy on difficult audio. A separate developer product, Rev.ai, exposes the same speech recognition through an API billed per minute, including a free open-source Reverb model for teams that want to self-host. Global subtitle translation covers 17-plus languages.
Key Features
- AI transcription — automated speech-to-text with speaker identification, returned in minutes.
- Human transcription — freelance transcriptionists deliver higher-accuracy transcripts for difficult audio.
- English captions — timed, 99%-accuracy captions for video content.
- Global subtitles — translates English video into 17-plus other languages.
- Rev.ai developer API — programmatic speech-to-text billed per minute, separate from the consumer site.
- Reverb open model — a free, open-source speech recognition model for self-hosting.
How It Works
A user uploads an audio or video file and chooses AI transcription for a fast, automated result or human transcription for higher accuracy on accented, noisy, or multi-speaker audio, with a freelancer completing the order. The same account handles English captions and global subtitle translation for video content. Developers building transcription into their own product instead call the separate Rev.ai API, which bills per minute of audio and offers both Rev’s hosted models and the free, open-source Reverb model for self-hosted deployment.
Technical Architecture & Overview
- Core Engine: Rev’s automated speech recognition models, plus the open-source Reverb model and a human transcriptionist network.
- Deployment: Web app and mobile recording app for the consumer product; REST API for Rev.ai.
- API Surface: Rev.ai bills per minute on pay-as-you-go or volume-committed plans, separate from the consumer subscription tiers.
- Known Limits: Human transcription and translated subtitles cost significantly more per minute than automated AI transcription.
