Show HN: DemoDay – Claude Plugin that creates demo videos for your projects

I needed to use more of my Claude Max sub - so now I have Claude make demo videos for my projects or new features.

Claude looks at your project, writes a script, drives your app, then it uses your Fal API key and Remotion to build out all the scenes. If a scene looks bad or something needs to be added/edited, just ask for a revision. It uses Remotion for editing which is free for individuals, but larger orgs need a license. Same thing if you use Eleven Labs for custom voices (needs a subscription)- otherwise Claude will use a generic voice from Fal.

Would love some feedback, especially for anyone that pays for other products that offer more polished product demos.
