huashu-motion went public on October 18. The next day, AI磊叔, who makes the Mac clipboard app Echo, left this comment on the creator's launch post: "来了，给 90 分～ 我的产品地址丢进去就出来了成品，画面的成熟度很高" (Here it is, 90 points. I dropped in my product URL and got a finished video. The visuals are very polished.) The video at the top of this page is the one attached to that comment.
In the eight days after release, people who build watch firmware, a content service, and a document formatting skill also made promo videos for their own products and posted them. The launch post that the creator, 花叔, published on X had 239,747 views and 1,815 bookmarks as of October 26.
Once a video is done, you click the scene you want changed in a preview page that opens in the browser, then write one line. 沐风AI, who makes the iOS app 鲸海语记, asked Claude Code: "用 huashu-motion 给我的产品做一支 60 秒发布片" (Use huashu-motion to make a 60-second launch video for my product). When the video came out, 沐风AI clicked the scene at 18.55 seconds and wrote "这个页面的时候，底部波浪跳动动画速度太快了" (On this screen, the bouncing wave animation at the bottom is too fast). The AI changed a single line, lowering that wave's time factor from 1.2 to 0.45, and left the waves in the deep-sea scene alone because their speed was set separately. The other note asked to shorten the subtitle to 「周报、月报或自定义分析」 (weekly or monthly reports, or custom analysis). 沐风AI wrote: "两条都是在画面上点一下、打一行字，AI 就改对了位置，而且没碰别的地方。" (Both times I clicked once on the frame and typed one line, and the AI fixed the right spot without touching anything else.)
huashu-motion is a free, open-source skill you add to coding agents like Claude Code and Codex. It draws scenes in code (HTML and GSAP) and generates the background music in code as well, not from recorded audio, so the output is plain web files and an MP4.
