sizzle-studio

Your launch video is a React repo. This is the real source of Speko's launch film - 4K, coded UI (no screenshots), AI voiceover. Clone it, point an AI agent at it, get yours.

Render the sample (no API key)

bun install
bun run dev      # scrub it live in Remotion Studio
bun run render   # 4K master -> out/sizzle.mp4

Make yours

Open the repo in Claude Code or Codex and paste:

Here is my product: <your landing page, README, or a description>.
Turn this repo into MY launch video: script, scenes, voiceover, render a preview.

The agent instructions (AGENTS.md, .claude/skills/sizzle) handle the rest: it writes the narration, rebuilds the scenes as your UI, and renders 4K dark + light masters.

Voiceover

One key powers the TTS (ElevenLabs eleven_v3 with emotion tags like [excited]) and the word-timed captions:

SPEKO_API_KEY=sk_live_... bun run voice

Get a key at platform.speko.dev - free minutes included, no card. bun run voices auditions ElevenLabs, Cartesia, Inworld, and OpenAI voices on one line.
