Comet vs Rev FAQ
- Which one is cheaper?
- Comet starts lower at $19/mo, compared to $29/mo for Rev.
- Can I use either one for free?
- Both offer free plans, so you can try each without paying. Start with whichever fits your workflow better and upgrade when you hit the limits.
- How do they charge?
- Different approach here. Comet uses usage-based pricing, while Rev goes with per-seat. That changes the math depending on your team size and usage.
- Which one is a better deal?
- Depends on what you need. Comet: At $19/mo entry, they're positioning as the accessible alternative to heavier MLOps platforms — clearly going after teams that find tools like Weights & Biases or Arize too expensive or too complex for pure LLM tracing use cases. The academic free Pro tier signals they're also playing a long game on developer mindshare. Rev: At $30-$60/seat, Rev sits in the mid-market band — not the cheapest (plenty of AI-only tools undercut this) but well below enterprise transcription services. They're clearly going after professional teams, especially in legal, who need more than a free Otter.ai account but aren't ready to negotiate an enterprise contract.
