i've used macwhisper (paid), superwhisper (paid), and handy (free) but now prefer hex (free):

for me it strikes the balance of good, fast, and cheap for everyday transcription. macwhisper is overkill, superwhisper too clever, and handy too buggy. hex fits just right for me (so far)

Tried to use it, installed, enabled permissions, downloaded the parakeet model for English and then it crashed every time I released the button after dictating. Completely unusable.
