The short answer
There are three ways to dictate on a Mac: the built-in dictation that ships with macOS, a cloud dictation app, and an on-device dictation app. Built-in dictation is free and fine for short, casual text. Dictation apps cost money and earn it by turning rambling speech into finished writing. The on-device kind does that without sending your voice anywhere.
| | Built-in macOS dictation | Cloud dictation apps | On-device dictation apps | |---|---|---|---| | Cost | Free | Paid, usually a subscription | Paid, usually a subscription | | Output | Raw transcript | Cleaned-up, formatted text | Cleaned-up, formatted text | | Where speech is processed | On your Mac for most languages | The provider's servers | On your Mac | | Works offline | Mostly, on Apple Silicon | No | Yes | | Custom vocabulary | Very limited | Usually | Usually |
Some apps blur the last two columns by offering both a cloud mode and a local mode. We build one of them, so this guide has a point of view, but most of it applies no matter what you end up using. If you want the app comparison instead, we keep an honest one at best dictation app for Mac.
Start with built-in dictation. It costs nothing, and its limits will tell you within a week whether you need more.
Set up macOS built-in dictation
Setup takes about a minute:
- Open System Settings, click Keyboard in the sidebar, and scroll to the Dictation section.
- Turn on Dictation and confirm.
- In the same section, pick your language, your microphone source, and the shortcut that starts dictation. The default is pressing the microphone key (F5 on most modern Mac keyboards); pressing the Control key twice is a popular alternative.
- Leave Auto-punctuation on if it is offered for your language. It inserts commas and periods as you speak, and it is better than dictating every mark yourself.
To dictate, click into any text field, press your shortcut, and talk. A small microphone indicator appears near your cursor. Press the shortcut again (or Escape) when you finish.
Built-in dictation is genuinely good at short, low-stakes text. A reply to a text message. A search query. A quick note while your hands are full. On Apple Silicon Macs it processes speech on your Mac for most languages, so it is fast, private, and works without a connection. For free software that is already installed, that is a strong baseline.
Where built-in dictation stops
The limits show up when you dictate anything longer than a sentence or two.
You are the formatter. Auto-punctuation handles commas and periods reasonably well, but structure is on you. New paragraphs, lists, quotes, and anything beyond basic punctuation must be spoken as commands ("new paragraph", "open quote"). Dictating a three-paragraph email this way feels like typesetting out loud.
What you say is what you get. Speech is messy. You repeat yourself, restart sentences, and say "um" while you think. Built-in dictation transcribes all of it faithfully, which is exactly what you do not want. The transcript of a perfectly normal spoken thought reads like a rough draft, because it is one, and you end up editing by hand anyway.
No real custom vocabulary. macOS picks up some names from your contacts, but there is no practical way to teach it your product names, your clients, or the jargon of your field. It will keep guessing the common word over your word.
Per-app quirks. Dictation behaves slightly differently depending on where you use it. Some text fields handle it cleanly; others lag, drop the first word, or fight with the app's own autocomplete. You learn which apps to trust it in.
None of this makes built-in dictation bad. It makes it a transcriber rather than a writing tool, and for many people a transcriber is enough. If you dictate a few short messages a day, stop reading here and enjoy the free option.
What a dictation app adds
A dictation app earns its subscription in the gap between what you said and what you meant to write.
The big one is cleanup. Modern dictation apps run your transcript through an AI pass that removes filler and false starts, fixes grammar, and adds structure, so a rambling spoken thought lands as a finished paragraph. The good ones format what you said instead of replacing it with what a model would have said. Tone matching goes a step further and adjusts the register to the destination: formal in email, casual in Slack, without you switching anything.
Custom vocabulary fixes the names problem. You add your people, products, and jargon once, and the transcription stops guessing. And because a dictation app inserts text wherever your cursor is, behavior is identical in every app. Same hotkey, same output quality, in Mail, Slack, Google Docs, or a code editor.
Epilude is a voice interface for knowledge work on the Mac: dictation with AI cleanup that works in any app, in Cloud mode or fully on-device with Local Mode. Cloud mode, the default, sends audio to subprocessors for transcription and cleanup. Local Mode runs Epilude Model 1 on your Mac instead: audio never leaves the Mac, and dictation keeps working with Wi-Fi off once you download the model. Which mode fits you depends on how sensitive your words are, and it is a choice you make once in Settings, not a compromise baked into the product.
If you write for a living, the cleanup layer is the difference between dictation as a party trick and dictation as your drafting method. We wrote up how that plays out for writers and content creators, where the bottleneck is rarely thinking speed and almost always drafting speed.
Make dictation stick
Whether dictation sticks comes down to habit more than software. Three things help.
Pick one hotkey and leave it alone. Whether it is F5 for built-in dictation or a push-to-talk key in an app (Epilude defaults to holding Left Command + E), the moment dictation lives under one reflexive keypress, you stop deciding to dictate and start doing it.
Start with low-stakes text. Slack messages, casual email, notes to yourself. You will make peace with speaking your thoughts out loud faster when a stumble costs nothing. Save the client proposal for week two.
Add your names and jargon early. If you use an app with a custom vocabulary (in Epilude it is called Vocabulary), spend five minutes on day one adding the names of your team, your clients, and your product. Every name it gets right afterward is friction you never feel.
Give it a week of real use before you judge it. Dictation feels awkward for the first few days, the same way a new keyboard layout does. Then one afternoon you answer an email while leaning back in your chair, and typing it starts to feel like the workaround.
Frequently asked questions
Is dictation on a Mac free?
macOS ships with free built-in dictation, and for short messages it is all you need. Dedicated dictation apps are usually paid subscriptions that add AI cleanup, custom vocabulary, and consistent behavior across apps. Most paid apps, including Epilude, offer a free trial, so you can test whether the cleanup layer is worth it for your writing volume before paying.
Does Mac dictation work offline?
Built-in macOS dictation processes speech on your Mac for most languages on Apple Silicon, so it generally keeps working without a connection. Cloud dictation apps need internet, because transcription happens on the provider's servers. On-device dictation apps work offline: Epilude's Local Mode, for example, runs Epilude Model 1 entirely on your Mac after a one-time download, so dictation works with Wi-Fi off.
How do I dictate into any app, not just Apple ones?
Built-in macOS dictation already works in any app with a text field. Click where you want text, press your dictation shortcut, and speak. Dictation apps do the same thing with a global hotkey and insert the finished text wherever your cursor is. In both cases, dictation is system-wide on the Mac; the difference is what the text looks like when it arrives.
Why does dictation get names and jargon wrong?
Speech recognition predicts the most statistically likely words, and your colleague's surname or your industry's acronyms are rare compared with everyday words, so the model substitutes something common. Built-in dictation offers no practical fix beyond hoping it learns from your contacts. Dictation apps solve this with a custom vocabulary you fill in yourself; once your terms are in the list, the model stops guessing against them.
