To dictate in any app on a Mac, put your cursor in the text field and start dictation — macOS's built-in Dictation types wherever the cursor is, so it works in Slack, Mail, a browser form, or a code editor. The catch is that it types verbatim and behaves identically everywhere; a dedicated dictation app also works in every field but adapts its tone to the app you're in.
Built-in Dictation already works in most fields
The Dictation feature Apple ships with macOS is not tied to one app. Turn it on in System Settings → Keyboard → Dictation, click into any standard text field, and press the shortcut — whatever you say is typed at the cursor. That covers the great majority of places you type: the Slack message box, a Mail compose window, a search bar, a browser form, the body of a note. If you can click into it and see a blinking caret, dictation can usually put words there. So 'can I dictate in any app?' is mostly yes for the built-in feature — the friction isn't reach, it's what comes out.
The real want: dictation that adapts to the app
Apple's Dictation behaves the same everywhere. It transcribes what you say word for word, including every 'um', false start, and thinking-out-loud detour, and it applies the same rules whether you're firing off a one-line reply in a chat window or drafting a formal email. But the way you'd write in each of those apps is different: loose and quick in a team chat, buttoned-up in mail, short and literal in a coding tool or a terminal. What most people actually want when they say 'dictate in any app' is voice typing that reaches every field and shapes the result to fit the app in front of you — not one flat verbatim stream pasted everywhere.
How a menu-bar dictation app fills every field
A dedicated dictation app solves both halves at once. It lives in the menu bar and listens on a shortcut rather than hooking into one app, so it isn't limited to Apple's list of supported fields. When you finish speaking, it cleans up the transcript into finished text and pastes it into whatever field is focused — the same mechanism regardless of app, so it works in Slack, Gmail, a browser form, a Markdown editor, or a terminal. On top of that it can carry a per-app tone: casual phrasing in a chat window, a more formal register in Mail, terse and literal in a coding tool. Same voice input, different output depending on where your cursor is.
Setting it up so it just works
Practically, the flow is: install the app, grant it the microphone and accessibility permissions macOS asks for the first time (accessibility is what lets it paste into the focused field), then click into any app and trigger it. Because the app owns its own capture and its own shortcut, you're not fighting Apple's function-key settings or its 30-second cap. From there you tune behaviour per app — how it's summoned, how formal it sounds — once, and it applies automatically each time that app is in front. The result is one dictation habit that follows you everywhere instead of a separate mental model for each program.
Dictate anywhere, sound right everywhere
Clavio is an AI dictation app for Mac that lives in your menu bar and pastes finished text into whatever app is in front — Slack, Gmail, browsers, editors, terminals — with a tone you can set per app. Summon it with ⌥ Space, the Globe key, a trackpad double-tap, a wake word, or always-on listening. It's free to try: 3,000 words a month, no card, macOS 14+ on Apple Silicon. Pro is £12/month for unlimited.

Common questions
Can I dictate into any app on my Mac?
For the most part, yes — macOS's built-in Dictation types wherever your cursor is, so any standard text field works: Slack, Mail, browser forms, editors. The limitation isn't which apps you can reach, it's that it types verbatim and behaves the same in every one of them.
Why does Apple's Dictation work the same in every app?
Because it's a single system feature that transcribes speech to text word for word, with no awareness of what app you're typing into. It applies identical rules everywhere, so a quick chat reply and a formal email come out in the same raw style. A dedicated app can instead adjust its tone to the app you're in.
How does a dictation app type into any field?
A menu-bar dictation app listens on a shortcut and pastes the finished text into whatever field is focused, using the same mechanism in every app. That's how it reaches places beyond Apple's supported fields — from a browser form to a terminal — and why it isn't tied to one program.
Can dictation use a different tone in different apps?
Yes, with the right app. Clavio carries a per-app tone: it can keep things casual in a chat window, formal in Mail, and terse in a coding tool, adapting the output to the app in front while the way you speak stays the same.
