Ten animated UI mockups for product, launch and dev-tool videos, rebuilt as HTML instead of screen recordings: phone message thread, team chat channel, coding-agent terminal session, terminal command run, desktop terminal window, desktop notification banner, code editor walkthrough, 3D code slab, exploded UI panels and an amber CRT console. Presets give typing speed (12-20 characters per second with seeded gaps), reading holds from character count, entrance easing and scale, camera lead before each action, text size as a share of frame height, and theme colors from MIT theme sources, from Charm VHS, Screen Studio, Emil Kowalski, Apple HIG and Netflix timing rules. Use when someone wants a fake text or Slack conversation, a terminal or Claude Code demo, a code walkthrough or an exploded UI shot in a video. NOT for recording a real screen or for real people's messages presented as genuine.

# App UI mockups: chats, terminals, code and notifications for launch videos

Ten UI scenes rebuilt as HTML so they look clean, read at a human pace and render the same every time. Typing, streaming and holds follow measured reading and typing speeds rather than guesses.

## Gates

- **Invented people, real product.** Use invented names and workspaces in chats; never put words in a real person's mouth or show a conversation as genuine when it is not.
- **No platform logos.** UIs are recognisable look-alikes; the platforms' names, logos and UI looks are their owners' trademarks.
- **Free fonts only.** Every font in the presets is OFL or Apache. Swap in the person's brand font only if they have a license for video.
- **Seek-safe.** Every value is a function of timeline time; randomness is seeded by frame. No `Date.now()`, `requestAnimationFrame` or unseeded `Math.random()`.
- **No credits here.** These templates render locally for free. Generated footage, voice or music is the varg-ai skill: call `estimate_cost` and wait for the person's approval before any generation.
