Customer support

Use the Interpret tab when a seminar, conference, or work meeting runs long. Source and translation stay side by side, and the finished session can be searched later. When you need to answer, use an AI reply and TTS. For a one-to-one exchange, open the Chat tab. A phone or tablet is enough.

Open the Interpret tab, choose your language pair, and tap Start. With continuous listening enabled, Butterbun keeps translating through extended presentations and meetings. Source and translation appear side by side. When you finish, you can save the session with a title.

In the Chat tab, listen in your partner's language or type directly. What they say is translated on screen, and Butterbun suggests context-appropriate replies. Send a line as text or play it with TTS. An internet connection is required.

When you end an interpret session, you can save it and add a title. In History, search by title, language, or content to reopen a seminar or meeting, review source and translation together, or share them.

Butterbun supports 23 languages, including Korean, English, Japanese, and Chinese (Simplified and Traditional). The full list is on the home page. In the app, pick your language and theirs to interpret that pair.
