LiveCap — Your Voice, Heard by Everyone

Imagine This

• Late-night gaming stream. "What did you say?" comments flow in from overseas, but you just keep speaking your native language. Automatically translated subtitles appear on screen, and viewers worldwide are captivated by your gameplay.

• International meetup in VRChat. When you speak in your language, subtitles automatically appear in the Chatbox in English. Your international friends understand your words and smile. Language barriers? They don't exist anymore.

• One-hour gaming commentary video. What used to take three hours for subtitles is now just drag & drop. You're using the saved time to brainstorm your next video idea.

This is daily life with LiveCap.
