anything2explainer

anything2explainer turns a topic into a narrated motion-graphics explainer video. It is a skill for Claude Code or Codex, not an app: the agent researches with sources, writes the script, generates voiceover, storyboards every shot, then writes each shot as a Remotion component. You get a 720p MP4 with subtitles, chapter cards and a progress bar, in English or Chinese.

Setup is real. You need Node 18+, ffmpeg, a Python environment with edge-tts, and kokoro plus espeak-ng for English voices. A 3 to 5 minute film takes about two hours with eight build agents working in parallel, and around 2 GB of disk. It stops at four checkpoints for your sign-off, including a 30-second preview before the full build.

Solo creators and educators who want explainers without learning After Effects get a lot here, and every shot is code you can fix one file at a time. Hours of parallel agents also means a real model bill. The same author's video-shotcraft covers product videos under Apache 2.0.

The catch is two licenses. The skill is PolyForm Noncommercial, so commercial use needs the author's permission. Remotion underneath needs a paid license, $25/mo per seat, once your company passes three employees.
