AssemblyAI vs Deepgram 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?
- Both use a usage-based model, so the comparison is straightforward — it comes down to features and limits at each price point.
- 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. Deepgram: Deepgram plays the developer-friendly, usage-first lane against AssemblyAI and cloud giants like Google/AWS speech APIs — cheap to start, transparent-ish per-minute rates, but pricing opacity creeps in once you're comparing STT models, TTS, and Voice Agent add-ons that aren't in the tier table. They're chasing technical buyers who want to prototype fast and scale on consumption rather than negotiate a seat-based contract upfront.
