VoiceFlow or macOS dictation

01 · Common ground

First, what doesn't set us apart.

Worth getting out of the way, because it's what most comparisons like this one overstate.

If someone tells you their dictation app «hears better» than the Mac and runs on the same device, ask them which engine.

Accuracy is the same. VoiceFlow has no engine of its own: it uses the one in macOS, just like system dictation. What one hears, the other hears.
Both work offline on a recent Mac.
System dictation punctuates, and punctuates well. Commas, full stops, question marks, and it turns «forty euros» into «€40». This isn't the dictation of ten years ago.

02 · The difference

You correct yourself out loud.

Talking isn't reading. You stumble, you say a time and change it halfway through. System dictation types what it hears — including the part you were correcting; VoiceFlow keeps the good one.

These examples are measured, not imagined: the same audio run through both paths.

Look at the first one. The system doesn't just leave the time you were correcting: it reads the «no» as a question. That text has to be gone over by hand, which is exactly what you were trying to avoid.

You say	And this gets typed
«See you tomorrow at two, no, make it three»	macOS dictation See you tomorrow at two, no, make it three. VoiceFlow See you tomorrow at three.
«The total is forty euros, sorry, fifty euros»	macOS dictation The total is €40 sorry €50 VoiceFlow The total is €50

These are the Spanish examples measured with Tools/comparar-con-apple.sh, rendered here in English. The engine behaves the same way: it punctuates well and leaves the correction in.

03 · And three more

Filler words, context, and your names.

Filler words gone. The «uh», the «so» and the «I mean» you start a sentence with never reach the text.
A polish level per app. In the terminal you want exactly what you said, because one changed word breaks a command. In an email you want it to read well. VoiceFlow remembers which one you use where.
Your proper nouns, spelled right. Your client's surname, your industry's acronyms, your tools: you say them once and they always come out your way.

04 · Fair's fair

Where system dictation wins.

No hedging, because these are real reasons.

If you dictate now and then and don't mind going over the text afterwards, the system one is plenty. VoiceFlow is for people who dictate many times a day and don't want to come back to what they wrote.

It's free and already installed. Nothing to download, decide or pay for.
It doesn't ask for Accessibility permission. VoiceFlow does, because it's the only way macOS lets an app type inside another one.
It's on the iPhone and iPad too, with the same gesture.
It covers more languages.
