Which one should you pick?
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.
Pick Vosk if
You’re building around developers building offline or embedded apps who need an open-source asr with mature bindings.. Vosk is a long-standing open-source toolkit built on Kaldi, with bindings for Python, Node, Android, iOS, and even Raspberry Pi. Accuracy lags Whisper but the small models run on devices with under 100MB of RAM.
