Why Mumble

More than just speech to text.

Polished text at your cursor

Hold, speak, release. Clean text lands where your cursor is, in Slack, email, Notion, your code editor. System-wide, no copy-paste.

Switch formats while you talk

Tap a key any time you’re still holding: clean text, bullet points, a custom prompt, or open a link.

Custom prompt, your format

Set an instruction once and reshape your dictation with a keypress: email, Slack tone, translation, or a one-paragraph summary.

Your words, spelled right

Add product names, client names, and acronyms to your Dictionary. Mumble stops guessing and gets them right.

Formatting

One input. Every use case.

Tap a format key while you’re still holding the dictation shortcut. Same words, the output your use case needs.

Dictionary

Names and jargon, spelled right.

Generic dictation tools mishear the words that matter most to your work, like names, acronyms, and specialized terms. Add them to your Dictionary once, and Mumble gets them right every time.

FAQ

Is Mumble's dictation free?

Yes. Mumble is in open beta and dictation is free to use during the beta period.

Does Mumble dictation work offline?

Yes, when Local Mode is enabled. In Local Mode, speech recognition and text output run entirely on your Mac, so dictation works with no internet connection. In Cloud Mode, an internet connection is required.

Which apps does Mumble dictation work in?

Mumble’s dictation works system-wide across macOS. You can dictate into your email client, Slack, Notion, Google Docs, browsers, code editors, and any other Mac app where you can type.

Can I change how my dictated text is formatted?

Yes. While you hold the dictation shortcut, a panel lets you pick an output format: clean text, bullet points, a custom prompt, or open a link. Custom prompts can reshape your text into a formal email, a short message, a translation, or a summary.

Is Mumble dictation private?

It can be fully private. In Local Mode, your audio is processed entirely on your Mac and never sent anywhere. If keeping voice data on your own machine matters to you, use Local Mode.
