Real AI agent use cases, with sources and setup prompts
Short answer: Point Claude Code or Codex at your app or website and ask for a 20 to 60 second launch video. The agent rebuilds your real screens in code with Remotion or HyperFrames, adds titles, captions and music, and renders an MP4; tools such as Remocn Studio, HyperFrames Studio or a one-command skill package the whole flow. Builders below made launch videos in 10 minutes to one evening, usually on a Claude or ChatGPT plan they already had. Use a video model such as Seedance only for shots you cannot capture, and watch the draft on a phone to fix pacing and easing before you post.
