You don't have to pay anything to dictate on a Mac — there are genuinely good free options. But "free" has a cost that doesn't show up on the price tag. Here's what's actually free, what you give up, and when a one-time purchase quietly saves you money.
The genuinely free options
Apple Dictation
Built into macOS, on-device for many languages, zero cost. Trigger it with a shortcut and talk into any field. Setup guide: how to use Dictation on Mac. Great for a quick message; it struggles with punctuation and jargon.
Aiko
A free, on-device Whisper app for transcribing audio files. No dictation workflow, but a solid free transcriber.
whisper.cpp
Free and open source, very fast on Apple Silicon, entirely command-line. Best for people comfortable in a terminal — details in whisper.cpp on Apple Silicon.
The hidden costs of free
- Correction time. Weak punctuation and misheard names mean editing every paragraph.
- No custom vocabulary. Free tools mangle the terms you use most.
- No cleanup. Filler words and false starts land verbatim.
- No history. You can't re-run a session with a better model.
If you dictate a few minutes a week, none of this matters. If you dictate daily, the math flips fast: a few minutes of cleanup per day adds up to hours per month.
Free vs subscription vs one-time
Many paid dictation tools are subscriptions — you pay every month, forever. That's the part we never understood: dictation is a feature, not a service. A one-time purchase sits neatly between "free but limited" and "subscription forever."
That's the bet behind Sotto: local Whisper and Parakeet models, custom vocabulary, automatic cleanup, and 90+ languages for $49 once (3 Macs, lifetime updates). Cheaper than a single year of most subscriptions, and your audio stays on-device.
Bottom line
Start free — Apple Dictation costs nothing and might be all you need. If you find yourself fighting it daily, a one-time purchase like Sotto pays for itself in saved correction time without locking you into a subscription. Compare the field in the best dictation app for Mac.
