A 15-second promo for Stuff, a to-do app: a phone, three words and a wall of lists.

## How it was made

Tools: Claude Opus 5.5

Prompt: 574 words, shown to signed-in members on the page, free with an account.

### Process

A first try, run inside the app's own code project so the model could use the real interface.

The creator's own prompt was eight words: "make a 15-second promo video for Stuff". The prompt shown here was written afterwards from the finished clip, so it describes what is on screen.
