The lesson
Demonstrate an AI feature by letting the viewer read the exact prompts and outputs, with almost no other on-screen copy.
The film shows the product UI tilted on a dark field. A prompt reads "Make a plan to refactor data loading to be optimistic," and the reply says "I created the PRD around the issues you surfaced," above a document card titled "Optimistic loading refactor." The film ends on "Linear. At your command."
Don't film UI that is unreadable at video size. Keep the habit of writing prompts a real user would type, and show the finished artifact.
