Knack: How it's done

Your product doing its job in small moves on a black stage lit by your colour. A prompt box types a first try, deletes it, types the real ask, an option gets picked, three modes rise and three steps arrive on light streaks.

How you get yours

  1. Paste your site. Siren reads your logo, colours, fonts and what you sell.
  2. Say what the video is about. A launch, a feature, a price drop. One line is enough.
  3. Pay once and watch it render. One video is $9.99, no subscription. On a plan it is 25 credits.

Already use Claude, Cursor or ChatGPT? Ask your agent for it by name through the Siren MCP: make a Knack video for our launch.
