AssemblyAI alternatives — common questions

What is the best free AssemblyAI alternative?
Deepgram is the strongest free option we list — speech-to-text API for developers. It is freemium, so check the free tier limits before committing.
Is there a cheaper alternative to AssemblyAI?
Yes — 1 of the tools on this page start below AssemblyAI's $0.12/hr. The cheapest is Deepgram at $0.0043/min.
Why should I switch from AssemblyAI?
Most people switch for one of three reasons: pricing that no longer fits their volume, a missing export option such as a watermark-free or higher-resolution output, or a workflow that does not match how they actually edit. If none of those apply to you, staying put is usually the right call.
