Deckset vs FreeShow

Deckset is a Mac and iOS app that converts plain-text Markdown notes into visually designed slide presentations without requiring manual slide layout work. Writers work in any text editor on Mac or Deckset's native iOS editor, and the app automatically generates slide designs from that Markdown content, applying one of more than 25 built-in themes. The app supports images, video, tables, code blocks, math equations, and diagrams within slides, keeps presenter notes off-screen during a talk, and exports finished decks to PDF. Deckset is used by teams at companies including Shopify, Mozilla, Basecamp, and Kickstarter, and is aimed at founders, educators, and technical presenters who prefer writing over dragging boxes around a slide canvas.
