Which one should you pick?
Pick OpenAI Whisper API if
You’re building around developers wanting raw transcription. Raw Whisper through OpenAI is still one of the cheapest ways to get high-quality transcription — $0.006/min for Whisper or gpt-4o-transcribe, and $0.
Pick Rev if
You’re building around court-quality transcripts. Rev's human transcription is the right answer when you need legally defensible accuracy or quotable transcripts — and the wrong answer when you just want subtitles. The pivot toward legal tools means the product feels less podcaster-shaped than it used to.
