An explainer engine · v0
Turn a paragraph into a video that plays itself.
Paste source material — get a self-contained animated explainer with synchronized narration. Hosted on a CDN, downloadable as a single HTML file, exportable to MP4.
01
A brief, then scenes.
Claude drafts a one-page editorial spine — the idea, the audience, the tone — and a scene-by-scene script you can edit before any audio is generated.
02
Captions are narration.
On-screen text and spoken voice are the same string. One source of truth — no out-of-sync subtitles, no second draft to maintain.
03
A real HTML artifact.
The output is vanilla HTML, CSS, and JavaScript. Hosted, downloadable, editable. MP4 if you need a file.
