Don't type it.
Say it.

Undertone turns your voice into clean, finished writing — no filler words, no missing punctuation, no cleanup afterwards. In your browser, or in every app on your computer.

Three seconds from thought to text

1

Hold

Hold Ctrl+Shift+Space anywhere — your email, your editor, a chat box. A quiet pill appears at the bottom of your screen.

2

Speak

Talk the way you actually talk. Ums, false starts, thinking out loud — all fine. Portuguese, English, or six other languages.

3

It types

Release. Your words appear at your cursor — punctuated, grammatical, and reading like you wrote them on a good day.

Speak rough. Publish clean.

um so like we should uh probably move the meeting to thursday

We should move the meeting to Thursday.

ah tipo me lembra de é de comprar café amanhã de manhã

Me lembra de comprar café amanhã de manhã.

hey can you uh send over the the q3 numbers before lunch

Can you send over the Q3 numbers before lunch?

Works everywhere

The desktop app types into any application — not just a text box on a website. The browser version is one click away when you're not at your machine.

Faster than your keyboard

Most people speak three to four times faster than they type. Say the paragraph; skip the typing and the tidying.

Your language, first-class

Dictate in Português, English, Español and more — and pin your language so short phrases never get misheard.

Nothing kept

Audio is transcribed and discarded. Recordings are never stored — your words go to the page, not to a database.

Questions

Does it change what I said?

No. It removes fillers and false starts, fixes punctuation and obvious grammar, and keeps your meaning and your language exactly as spoken. Questions stay questions — it never answers them.

Which platforms are supported?

Any modern browser today, and a Windows desktop app with the system-wide hotkey. macOS is on the roadmap.

How long can I dictate?

Up to three minutes per press — roughly 400 spoken words. Release and hold again for more; it appends where you left off.
