Whisper works quite well on Apple Silicon with simple drag/drop install (i.e. no terminal commands). Program is free; you can get an M4 mini for ~$550; don't see how an online platform can even compete with this, except for one-off customers (i.e. not great repeat customers).
We used it to transcribe ddaayyss of audio microcassettes which my mother had made during her lifetime. Whisper.app even transcribed a few hours that are difficult to comprehend as a human listener. It is VERY fast.
I've used the text to search for timestamps worth listening to, skipping most dead-space (e.g. she made most while driving, in a stream of not-always-focused consciousness).
