Cerebro Keyboard

The only keyboard that's not a keyboard. Speak, transform with AI, done. Try it free.

Cerebro is the only keyboard that's not a keyboard.

It completely changes the way you write texts and messages. Instead of tapping tiny keys, you just speak. Cerebro is a voice-first keyboard with backwards keyboard compatibility — because sometimes you still need to type a quick "ok".

Powered by advanced speech-to-text AI, one of the most accurate transcription engines available. Speak naturally, get clean text in under 3 seconds — or let AI transform it into the perfect tone. No app switching. No copy-pasting. It just works, everywhere.

KEY FEATURES

• Voice-First Design — Tap the orb and speak. That's it. The keyboard is there if you need it, but you won't.

• Works in Every App — Cerebro installs as your system keyboard. Use it in Messages, WhatsApp, Notes, Email, Slack, and any app where you type.

• Background Flow Sessions — Start a recording and switch to other apps. Cerebro keeps transcribing in the background so you never lose a thought.

• AI Text Transforms — Speak naturally, then let AI rewrite your text in any style. Choose from built-in modes like Professional (business tone), Casual (friendly), Concise (removes filler), Clean (profanity filter), and English (translation & grammar fix) — plus fun modes like Pirate and Yoda. Create unlimited custom modes with any prompt you want.

• Custom Dictionary — Add names, technical terms, and specialized vocabulary so Cerebro always gets your words right.

• Track Your Time Saved — See how much time you save compared to typing. The average user saves over 40 minutes per day.

PRIVACY BY DESIGN

Your voice stays yours. Audio recordings are deleted immediately on our servers after transcription — we never store what you said. Transcribed text and audio recordings are only stored on your device. No keystroke logging. No content tracking.
