AssemblyAI vs Rev FAQ
- Which one is cheaper?
- One or both use custom pricing, so it depends on your specific needs.
- 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. AssemblyAI 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. AssemblyAI: They're positioning as the developer-friendly, API-first alternative to Deepgram and Rev AI — competitive on price at scale but differentiated by the breadth of AI features (LLM Gateway, multichannel, etc.). The AWS Marketplace listing signals they're actively chasing enterprise procurement budgets. 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.
