YouTube · Twitch

The first release will connect to YouTube and Twitch chat. Official API chat connections are implemented. Public OAuth verification and checks with real accounts and live output are handled separately.

Prepare your stream

  1. Add character images in Fan Characters and assign them in Viewer Settings.
  2. Choose account permissions and a target broadcast in Stream Connections.
  3. Choose a game under Play with viewers and share its on-screen participation guide.
  4. Paste the game or broadcast remote’s display address into an OBS browser source.
  5. Check local audio and OBS audio separately. If audio doubles, adjust the desktop-audio and browser-source routes in OBS.

Prepare your PC and files

  1. The target platform is a 64-bit PC running Windows 10 22H2 or Windows 11. Prepare OBS or another streaming application separately.
  2. Live chat requires internet access, permission from the streamer’s account and a broadcast with chat available.
  3. Viewer count, ball count, concurrent displays and resolution affect load. Test your intended setup and audience size before going live.
  4. Check broadcast and commercial-use rights for characters, music, images and fonts. The PC-font option selects fonts installed on your computer.

Connections and saved files

  1. In Privacy and saved records, check the scope of disconnection, saved-login deletion, platform revocation and fan-record deletion.
  2. Manage your own calendar notes, recordings and exported backups. The privacy policy explains processing, retention and deletion.
  3. Choose Yes when closing to save progress and end connections and games. No keeps the broadcast running and minimizes to the tray.

Shared settings

  • Korean, English, Japanese and Simplified Chinese are available, with light and dark themes and a colorblind mode. The app starts in English; use the language selector to change it.
  • Adjust character size, movement speed, names, bubbles and display times. Choose default, random or named character assignments.
