Inbox triage is mostly the same five replies in five tones. Three Mac dictation apps that turn rough speech into a sendable email, with the screen-context tip that makes Murmur do half the thinking for you.

The hard part of email isn't the typing, it's the framing. Most replies are some version of "yes thanks," "no but explain why," "let me check and come back," or "loop in the right person." The thinking takes 10 seconds; the writing takes 90.
Dictation collapses the gap. Speak the rough idea ("yeah this works, can you push to next week, copy in Sarah") and the AI rewrites it into "Sounds good, let's push to next week. I've copied Sarah in for visibility." You did the thinking; the dictation app did the typing.
1. Apple Dictation. Free. System Settings > Keyboard > Dictation > on. In Gmail or Apple Mail: click the body, press fn twice, talk. You'll have to say "comma," "period," "new paragraph" yourself.
2. Murmur. $29 once. Download, install, set up your Claude API key. In any email client: click the body, double-tap right Option, talk a rough draft. Murmur takes a screenshot of the email thread above, sends both to Claude, and pastes a polished reply that addresses the original message.
3. Wispr Flow. $12/mo. Sign up, install. Hold their hotkey, talk. The cloud transcribes and polishes. Output is the slickest of the three but it doesn't see the thread you're replying to.
Most dictation apps are blind. You speak; they polish your speech. They don't know you're replying to a specific email, so the rewrite is generic.
Murmur's AI mode and Silent mode capture a screenshot of the active window when you trigger them. That image goes to Claude alongside your transcribed speech. So if you're staring at a thread that says "Hi James, can we move the Tuesday meeting to Wednesday at 3pm?" and you double-tap and mumble "yeah, Wednesday 3 works," Murmur pastes:
"Hi [name], Wednesday at 3pm works for me, see you then."
You spoke 5 words; Claude wrote a complete reply because it could see what you were replying to. That's not a feature you find anywhere else for $29 lifetime.
The same speech should produce different output depending on who you're emailing. A mumbled "looks good let's ship" goes to:
Murmur lets you save multiple custom prompts and switch between them with a menu-bar dropdown. Wispr Flow auto-detects the app and adjusts. Apple Dictation transcribes literally and you handle tone yourself.
For most people, two prompts cover 95% of email: one for "internal/casual" and one for "external/formal."
Click into the email body, then press your dictation hotkey. Apple Dictation: press fn twice. Murmur: tap right Option for raw, double-tap for AI polish that knows it's an email. Wispr Flow: hold their hotkey. Text inserts at the cursor.
Murmur for AI polish that reads the email you're replying to and matches its tone, $29 once. Wispr Flow for the most polished output of any app, $144/year. Apple Dictation for free raw transcription if polish doesn't matter.
Murmur and Wispr Flow can. Murmur's AI mode adds "Hi [name]" and "Best, [you]" if your prompt asks. Wispr Flow does this by default. Apple Dictation transcribes only what you say, so you have to dictate every greeting word-for-word.
Murmur's AI mode takes a screenshot of the active window before polishing, so Claude sees the email thread you're replying to and writes a response that addresses it directly. Wispr Flow and Aqua Voice don't do this; they polish blind.
Both. Mac dictation pastes wherever the cursor is, including web inputs (Gmail, Outlook web) and native apps (Apple Mail, Outlook desktop, Spark, Mimestream). The only thing that matters is that the email field has focus.
Murmur is the only dictation app that reads what's on your screen before writing the reply. $29 once, no subscription, audio stays local.
