What Apple Dictation already does well
It is easy to be unfair to Apple Dictation, so start with what it gets right. It is system-wide: press the dictation key and it types into whatever field has focus, exactly the way a dedicated app does. It punctuates automatically in most languages. It understands spoken commands for line breaks, capitals and symbols. And on any Mac with Apple silicon, the speech model runs locally — the audio does not leave the machine, and dictation keeps working with the Wi-Fi off.
That last point is worth more than most comparison pages admit. Offline dictation is not a niche preference. If you write on planes, in hospitals, on a boat, or on a machine that is not allowed to talk to the internet, the conversation ends there and Apple wins it.
It is also zero-friction. There is no installer, no licence, no permission dialog, and no vendor who might change the terms next year. For a lot of people, that is the whole decision.
