Practice a livestream scene with AI captions and synthetic audience comments before going live.
Stream Scene is an AI stream coach for practicing a livestream screen before you go live.
Preview a mobile streaming scene with camera, viewer count, gifts, live-style chat, and optional AI captions. When AI Audio is turned on, your microphone speech can be transcribed into captions and used to generate synthetic audience comments that react to your topic.
Key features:
- Livestream-style camera preview for practice
- Simulated viewer count, likes, gifts, and chat
- AI captions generated from microphone speech
- Synthetic audience comments that react to your topic
- Viewer-style replies between comments
- English and Japanese modes
- No login required
Camera video is used for local preview and is not uploaded. Before AI Audio starts, the app explains that microphone audio, generated transcript text, selected language, and recent in-app chat context are sent to Subcontroller LLC's Stream Scene API and OpenAI, L.L.C. for captions and AI comments.
