jastfan / explainroo-ui
Visual UI for Explainroo. Explainer videos and product demos made by your AI agent. Free and open source: a local voice (Kokoro), word timing (Whisper) and a canvas renderer turn a script into a narrated MP4.
Why this job: topics: video-generation
What it does
- Hand-Drawn Vector Aesthetics. Powered by Rough.js with natural pencil wobbles, marker strokes, and cross-hatch fill physics.
- Word-Level Synchronization. Tie any visual element (server, database, terminal, arrow) to a specific word. It pops into view at that exact millisecond.
- Web Audio Narration Engine. In-browser speech synthesis with customizable speech rate, pitch, and voice selection.
- Custom Voiceover Audio Import. Upload external .mp3 or .wav voiceover tracks per scene with live playback preview and instant audio ducking.
- Auto-Ducking Background Music. Generative ambient harmonic chords that dynamically lower volume whenever the narrator speaks.
