explain.ink: Hand-drawn Explainer Video Generator

Turns a topic, a script, or a document into a finished hand-drawn explainer video with voiceover. Real drawing, not slideshow fades: strokes are traced and animated on scene by scene, the way a person sketches at a board.

Fully headless pipeline. Text goes in, the system writes the narrative, splits it into scenes, generates the artwork, traces it to SVG strokes, animates the draw-on, synthesises the voiceover, and assembles the final MP4 with FFmpeg. No manual editing step anywhere in the chain.

Stack: TypeScript, Vue 3, Express, FFmpeg, Docker. Self-hosted, built on the Typus framework.

Media handling throughout: image generation, SVG rasterisation and stroke tracing, frame assembly, audio and video muxing, encoding.
