Answer in their language, in your words

Highlight the message you need to answer, type your point in Vietnamese, and Companion drafts a natural, work-appropriate reply in the message's language — not a word-for-word translation.

Context-aware — reads the original message to match tone & formality.
Auto language — detects Japanese / English from the selection.
One-click copy — paste straight back into the chat.

# Original (you selected): 会議の資料を送っていただけますか？ # Your reply (Vietnamese): ok mình gửi trong chiều nay nhé # Companion drafts (Japanese): 承知しました。本日中に資料をお送りします。
