Postday: Install, post, watch the numbers

Install, post, watch the numbers. Your app installs from a store row, the composer builds, your launch line types in with your picture under it, the camera dives onto Post, and the likes and views start coming.

This is one brand’s version. Yours gets your logo, colours, fonts, words and product screens, in the same motion.

Made for

  • A launch you want to see land
  • Products and announcements that live on a feed
  • Pick the platform your audience uses

Pick another when

  • The story is a chat thread: Contact
  • An agent does a job instead: Courier

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 Postday video for our launch.
