Chuyi – Chat Translator

Translate web chats in real time: bilingual incoming messages and one-click translation of your replies.

Chat with anyone in any language, right inside the web chat apps you already use. Chuyi shows a translation under each incoming message, so you can read the original and the translation together. Before you send, press Alt+T or click the 译 button to translate your draft into the other person's language. Chuyi never sends a message for you. You review the draft and press Enter yourself. Supported sites: WhatsApp Web, Telegram Web (both the A and K versions), and Messenger (messenger.com and facebook.com/messages).
