Write messages
with your voice.

Dictate a reply, turn rough thoughts into notes, or edit selected text by speaking.

New in Mac 6.0.0: recordings to transcripts, notes & summaries. Source build; public download still v5.

Free app. Your Google or OpenRouter key; AI usage billed separately.

Hold Fn on Mac or the mic on Android. Speak, then release.

You say

“Um, tell Priya I’m running five minutes late, and they can start without me.”

A possible result

Hi Priya, I’m running five minutes late. Please start without me.

Illustrative example, not a live recording. Results vary by model.

For the writing you do every day.

Reply to a message or email.

Say what you want to send instead of typing a long reply. Choose professional mode for a more formal draft, then check it before sending.

Turn thoughts and recordings into notes.

Dictate an idea in bullets mode. With the Mac 6.0.0 source build, import a saved meeting or lecture for a transcript, detailed notes or a summary. See how audio import works.

Fix a draft without retyping.

Select a passage and say “Make this shorter.” Review the proposed edit and any protected-value warnings before applying. If replacement can’t be verified, copy and paste instead.

Choose your device.

Free, open-source apps. Connect your own Google or OpenRouter API key. Voice processing needs internet and is billed by your provider.

Before you start.

Does voice typing need internet? Where does my audio go?

Yes. Audio and instructions go directly to your selected provider; voice edits also send the selected text. Provider data policies apply. Ordinary Android keyboard typing works offline. Read the privacy details.

Can I dictate in Hindi or Hinglish?

Use preserve-language instructions or Translate to English mode. Quality depends on the audio model and recording. Android’s typing layout is English (India); a dedicated Hindi layout and explicit Roman/Devanagari controls aren’t included yet.

Will voice editing work in every app?

Not every editor exposes a verifiable selection. Review the proposed edit; use Copy and manual paste if replacement isn’t available. Voice processing never sends your message automatically. See the Mac or Android editing guide.
