TapCast — Demo video

TapCast is a Zero-UI, “tap-to-listen” AI radio that removes decision fatigue from audio discovery. Most audio and news apps still force you to browse, scroll, and choose—right when you opened them to rest your eyes. TapCast flips that: you tap once to start, and the AI handles what to play next. The interface stays minimal with just a Play button and a Vibe Dial (light ↔ deep) to set your listening mood. Under the hood, TapCast continuously learns from implicit feedback—skip timing, completion rate, and vibe preference. When you skip, the system instantly cancels playback, generates a natural DJ-style bridge, re-scores candidate content, rebuilds the queue, and resumes with a better fit. A /presenter view visualizes both user behavior signals and the AI’s real-time decisions to prove the programming logic behind the experience.
