- free tier: Pay-as-you-go with 'Free credits equivalent to 5 hours of Reverb ASR (free credits can be used for all products)'. Reverb Transcription is USD 0.20 an hour, so the grant is USD 1.00 of usage: 5 hours of Reverb English, or 200 minutes of Whisper Large at USD 0.005 a minute, or 333 minutes of Forced Alignment at USD 0.003 a minute. | unit: hours | metered on: wall-clock | read on: 2026-10-22 | source: [1] | note: one-time-credit

- limits:
  - volume-quota (binding): USD 1.00 of credit is the whole allowance: five hours of the cheapest English model, or three hours twenty minutes if the work needs Whisper Large, and nothing renews. [1]
- limits note: USD 1.00 of credit is the whole allowance: five hours of the cheapest English model, or three hours twenty minutes if the work needs Whisper Large, and nothing renews.
- binding note: the same as limits note
- interface detail: HTTP API with reference documentation at docs.rev.ai/api, and official Java, Node and Python SDKs listed at docs.rev.ai/sdk
- tooling: official Java, Node and Python SDKs (docs.rev.ai/sdk); the page names no CLI
- composes with: five hours of Reverb is enough to transcribe a small corpus once and no more; the interesting composition is the 15-second minimum, which on a folder of short clips burns the credit on silence.
- reliability: no reliability event recorded
- notes: These are inference credits, not general compute. The direct read of rev.ai/pricing returned a JavaScript shell with no price text; the quotes above come from the search index rendering of the same vendor URL on the same day, which is the vendor's text but retrieved indirectly. A third-party review (aiappstacker.com) reported the same 5-hour grant, corroborating it. Not established: whether a card is demanded at signup.
