Which one should you pick?
Pick NVIDIA Riva if
You’re building around teams with gpu clusters that need low-latency on-prem transcription.. Riva is NVIDIA's containerised speech stack, with Parakeet and Canary models that are genuinely competitive on English WER. You run it yourself, so latency and data residency are fully under your control, but you also own the GPU ops cost.
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.
