**Turn a script into a narrated, word-synced explainer video.** Free local voice (Kokoro), images and articles from the web with licences recorded, clips, and browser-rendered motion graphics. 16:9 for YouTube or 9:16 for Reels, Shorts and TikTok. No After Effects, no cloud, no API keys.

It also ships as a **Claude Code skill** (`SKILL.md`): drop the folder in `~/.claude/skills/` and Claude plans the shots, fetches the pictures, and builds the video from your script.

1. Voice: Kokoro TTS, sentence by sentence with natural gaps. Any recorded narration works too.
2. Align: whisper word timestamps. Every shot is anchored to a phrase, so re-recording the voice never breaks the sync.
3. Assets: images the relevant Wikipedia articles actually use (licensed, with a manifest and an attributions file), article screenshots scrolled to the paragraph, video clips cut into frames, made cards and diagrams.
4. Timeline: a tiny Pyth
