📖 What is OneComme?
A Japanese-made comment viewer that gathers chat from the major sites — YouTube, Twitch, Niconico Live, TwitCasting, SHOWROOM, Mirrativ, Kick — into a single screen. It includes text-to-speech that works without any extra software, a queue list for viewer-participation events, on-screen effects triggered by chat, and templates for customizing the look. It runs on Windows and macOS, and the core features are free. Remote View, surveys, and chat translation are PRO features.
💡 When to Use It
Use it when you're streaming to several sites at once and don't want to miss chat on any of them. Even when you're locked into a game and can't watch the screen, the text-to-speech reads chat out loud for you. In viewer-participation multiplayer streams, anyone who types the entry keyword is queued automatically, so you can run sign-ups entirely from the chat panel. Swap the template and the chat bubbles can match your stream's design.
