AssemblyAI alternatives
The 8 closest alternatives to AssemblyAI, which has a free tier. Each one below does roughly the same job from a different angle.
Why people move off AssemblyAI
- Universal-2 at $1.65/hour is significantly more expensive than baseline transcription options
- LeMUR token costs add up quickly on long audio files with complex analysis
- Language support outside English, though improving, is less thorough than some competitors
- No TTS product, so voice agent deployments require a separate synthesis service
Worth weighing against what it does well: leMUR is a genuinely differentiated feature for extracting intelligence from audio at scale
