Which one should you pick?
Pick AssemblyAI if
You’re building around developer transcription api. AssemblyAI isn't an app — it's an API. If you're building a product that needs transcription, sentiment analysis, or speaker diarization at scale, it's one of the few options that pairs accuracy with reasonable pricing and serious infrastructure.
Pick Deepgram if
You’re building around enterprise voice infrastructure. Deepgram is what large companies use when they're embedding voice into a product and need someone on the other end of an SLA. Accuracy is competitive with AssemblyAI and latency is excellent for real-time use cases.
