Translate as you type

Write in your native language, send in any of 55+. No copy-paste, no app-switching. Inside iMessage, WhatsApp, Mail, every app.

Download on the App Store

The standard way to translate an outgoing iPhone message takes 30 seconds and 4 app switches. An AI keyboard does it in 2 seconds, in place.

For anyone who writes across languages — international family, multilingual work, traveling, dating apps — a translation keyboard saves 30 seconds per message. That compounds fast.

How to do it with KeyAI

  1. 1

    Switch to your AI keyboard in any app

    In iMessage, WhatsApp, Mail, or anywhere — long-press the globe icon (🌐) to switch keyboards.

  2. 2

    Write your message in your native language

    Type naturally. Don't worry about phrasing for the target language.

  3. 3

    Select the text

    Tap and hold to select your draft (or skip if the keyboard auto-uses current text).

  4. 4

    Tap Translate → \{target language\}

    Choose from 55+ languages. The keyboard sends the text to the translation engine, gets a result back, and replaces in place.

  5. 5

    Send

    Hit send. Total time: 2-3 seconds. Total app-switches: zero.

Example

Before
"Thanks for the file, looks great — one small change on page 3 if you have time."
After (with KeyAI)
"Gracias por el archivo, queda genial — un pequeño cambio en la página 3 si tienes tiempo."
In-place Spanish replacement. Inside whatever app you're in. Send.

Tips

  • • For specialized terminology (medical, legal, technical), spot-check the translation before sending.
  • • For 1-on-1 chat with a known language partner, translation is often optional once both sides know each other's strongest language.
  • • Apple Translate works for incoming messages (long-press to translate) — pair with KeyAI for outgoing.

FAQ

How accurate is keyboard translation in 2026?

Modern LLM-based translation (KeyAI, CleverType) is significantly more context-aware than older Google Translate. For major languages — Spanish, German, French, Portuguese, Italian, Dutch, Japanese, Korean, Mandarin, Arabic — accuracy on everyday messaging and email is excellent.

Which keyboard translates the most languages?

KeyAI supports 55+ languages on-tap. Apple Intelligence doesn't translate at all. Gboard has more raw language coverage (100+) but uses an older translation engine via a separate UI.

Does it work in WhatsApp?

Yes — every iOS app. Including iMessage, WhatsApp, Telegram, Signal, Mail, Gmail, Outlook, Instagram, X, Tinder, Hinge.

Is translated text private?

The text is sent to the keyboard's translation engine (KeyAI uses OpenAI), then returned and inserted. Nothing is logged in the background. iOS automatically blocks the keyboard from password and credit-card fields.
