Deepgram transcribes audio through an API, with speaker separation, custom vocabulary, and a streaming mode that returns words while the caller is still talking. That combination is why it turns up inside contact centres, meeting recorders, and voice agents rather than in a consumer app, and its models hold up on narrowband phone audio where general-purpose recognisers struggle. It suits backend engineers adding transcription to a product.
Who it is for
Backend engineers embedding transcription into a product rather than buying a notes app.

Where it falls short
It is infrastructure, so you still build the interface, the storage, and the redaction yourself, and per-minute billing on a large archive of old recordings gets uncomfortable quickly.
Pricing
