Where Showoff comes in

Showoff adds App Store sets for every store and language, launch videos cut to the beat, and working together in one scene. And your AI works in the same editor over MCP, with a review before every save.

Launch videos

Your launch, as a film. Cut to your song.

Hand your AI a few screenshots and a song. It builds a launch video in which the device lands on the drop and the camera glides from shot to shot without a single cut.

How it works

Launch videos come from your AI via MCP: part of Pro, and free to try for 3 days.

App Store sets

Every image for the store. In every language.

Create a set, drop in your screenshots and write the headlines. Showoff puts one big phone into every image, adds one highlight across two images and exports every size for the App Store and Google Play as one ZIP.

  • Up to ten images on one stage, one highlight across two
  • Headlines in several languages, one folder per language
  • Sets for iPhone, iPad, Mac and Google Play

Auto motion

Mark what matters. The camera does the rest.

Draw a few areas on the display, and Showoff turns them into a camera move with real perspective, from one area to the next. The same scene becomes a video without a single keyframe.

  • Areas drawn straight onto the screen
  • Real 3D perspective, not a panned picture
  • Roll again for a different move over the same areas

Pair your phone Soon

Your phone becomes the remote.

Scan the code from the editor with the Showoff app. Your phone’s screen streams live onto the device in the scene, and when you turn the phone in your hand, the device on stage turns with it.

  • Live screen, or a screenshot at full resolution
  • The device follows your hand
  • Paired in seconds with a code

AI and MCP

Build, edit, cut. All in one conversation.

Your AI works in Showoff the way you do. It creates projects, puts screenshots on devices, sets camera and background, highlights details and builds whole App Store sets. Before anything is saved, Showoff checks the picture like an art director.

  • App Store images, website mockups and launch videos, all through the same connection
  • Watch live what your AI is working on, and bring back any earlier version
  • Free to try for 3 days
Everything your AI can do

Switching from Ultramock

Showoff has a free plan with every device in every color, unlimited exports in 720p and no watermark. Pro adds full-quality exports up to 4K, 60 fps, motion blur and your AI via MCP.

Projects do not move between tools. Your screenshots and screen recordings do: drag them into Showoff, start from a template, and the scene is ready in minutes.

Yes. Films with entrances, loops and camera moves export as MP4 or WebM at up to 60 fps, and your AI builds launch videos to your song over MCP.

No. Entrances, exits, continuous motion and a camera that travels across marked areas do the job, and every position stays editable.
