Show HN: TextAnimations.online – Generate MP4/GIF animations from a prompt (textanimations.online)

Recently I had to make an intro animation for a product demo, and the quickest way I could think of doing was to screen record an LLM-generated HTML/JS page with the animation.

I turned that idea into a polished project here. It is super fun to play with. I've been creating all kinds of custom-text GIFs to send to friends.

Under the hood, it is generating HTML and recording the video client-side.

Would love to hear feedback on it!
