Choose languages

Each language shown = 1 API call per word typed. Select only what you need — 3 to 5 is ideal.

Translate in multiple languages at once

Type in any box — all others update instantly.

Text is sent to Google Translate for processing. Nothing is stored. / Le texte est transmis à Google Traduction. Rien n'est conservé.

ℹ️ How it works

Type in any box. The moment you stop typing, all other visible language boxes translate simultaneously — one API call to Google per box shown.

1 Click Languages ✎ to choose which languages you want to see. Search by name, check the ones you want, press Apply.
2 Type in any language box. All other boxes translate at once.
3 Copy any result with ⎘, or clear everything with ✕.

Why keep fewer languages? Each visible box fires a separate call to Google Translate. More boxes = more API calls = higher risk of hitting Google's daily limit and getting temporarily blocked. 3–5 languages is the sweet spot for daily use.

The real power — learn a third language while you work.

Add a language you're learning alongside the ones you already use. Working in French and English? Add Italian as a third box. Every time you write something, you instantly see how Italian expresses the same idea — no extra effort, no separate app. Language absorption built into your daily routine.
