Voice dictation / macOS

A little
less typing.

For the note, the message, the thought
you’d rather say out loud.

Mercurius turns your voice into text in the Mac apps you already use.

The app

Hold a key.
Say your piece.

Then let go and carry on.
Mercurius puts the words into the app you’re using, so you can stay with the thought.

01 / Dictation

Write where you work.

Notes, emails, messages. Use your dictation shortcut in the app you have open.

02 / Your vocabulary

Keep the names right.

Add the people, projects and words you use. Save phrases you find yourself repeating.

03 / Optional cleanup

Leave the ums behind.

Choose whether to tidy filler words and punctuation. Set a writing style for each app.

Your Mac. Your choice.

Decide where
the words go.

On your Mac.

On-device speech with AI cleanup switched off keeps your audio and text on your Mac. No per-call API charges.

Or through a provider.

Cloud speech sends audio to the provider you select. Optional AI cleanup sends text to a cloud provider. Provider charges or credits may apply.

Still in the workshop.

Coming soon
to your menu bar.

We’re building Mercurius for everyday use on the Mac. A public release and an open-source repository are planned. Neither is available yet.
