During the initial Limited Beta, we're staggering access by Theme as each system moves from Composer-Compatible to full Composer-Enhanced status. If you'd like to get in early, Join the Waitlist and we'll do our best to accomodate – you'll otherwise receive a Notification once one of the themes in Your Library is updated for full Targeting support.
All Hands On Deck(s).
Composer is currently in Limited Beta
First Things First
Composer is an Automation Engine that takes Plain Text descriptions of Objects, Slides, or entire Presentations & generates AppleScript routines to automate their production in Keynote for MacOS. It's predictable, repeatable, and fully transparent.
Compose a Build Script
Pass your show to Composer to get down to work: Composer uses Latent Intent to map your script to the appropriate standard layouts, and writes the routines required to build the show in Keynote.

Examine & Build
Composer generates open, native AppleScript files for MacOS Script Editor: so you can examine every command or make your own edits before runtime.
Build Anywhere
Composer is right at home in any theme following standard Keynote naming conventions, with full support for Apple's built-in themes in all standard Language Localizations included in Keynote 14. If the Standard routes don't cover it, you can target specific Layouts by Name in any Target Theme using Named Route tags.
Global Standard Routes
Composer is designed around the native Keynote topology. Simply describe the contents of your slide: basic combinations of Titles, Body matter, or Photographs will auto-map to one of Keynote's Standard Layouts without any additional instructions, in any lanuage Keynote supports.
A Title + a Bullet List will produce a Title & Bullets slide (or its localised equivalent). Add a Photo to route to Title, Bullets & Photo instead. Or just a simple sentence to make a bold Statement.
Was that List actually today's Agenda? No problem: add a Target Layout tag and Composer will change course to wherever you point.

Engineered for Pros
In Composer-Enhanced themes like Chicago, you can get even more detailed – with precise Object-Level and Sub-Element Targeting allowing you to define even the most complex layouts.
Target by Object
In a Composer-Enhanced theme, you can target scripted changes to any individual placeholder on the layout.


Target by Sub-Element
And on Layouts that include complex, multi-element placeholder text, you can target by Sub-Element Text to dial in with precision.
