MoodCast generates personalized cinematic audio experiences — pick a mood and get an AI-narrated story, original music, and timed sound effects, all created in seconds. It uses 4 ElevenLabs APIs in parallel: TTS v3 with Audio Tags for emotional narration, Music API for scene-matched instrumentals, Sound Effects for cinematic cues synced to story moments, and Conversational AI as the story-writing engine. Built entirely with Kiro using Specs for structured feature development, Steering docs for hackathon focus, and Agent Hooks for automated testing. What makes it special: one tap turns a mood into a full audio movie — voice, music, and sound design composed together, not stitched from a library.
