Deckset vs ShareSpeak

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.

ShareSpeak is a desktop teleprompter application built for Mac and Windows that is designed to be invisible during screen sharing and recording. It places a scrolling script over your screen with AI-powered voice or manual controls, so presenters, educators, and content creators can stay on message without fumbling through notes. The app also includes a Notch Bar mode for MacBooks, placing the teleprompter right next to the camera to support natural eye contact while presenting.

• Writing in Markdown is much faster than manual slide design for technical content
• Strong native support for code blocks and math, unlike most mainstream slide tools
• Any Mac text editor can be used to author the underlying Markdown
• Endorsed and used by well-known technology companies

• Invisible during screen shares and recordings, so the prompt never appears in the final output
• Voice scrolling keeps pace hands-free while presenters stay in control of speed
• Notch Bar beta mode puts scripts next to the camera on MacBooks for natural eye contact
• One-time purchase with lifetime updates and no subscription fees

• Mac and iOS only, with no native Windows support
• Less visual, direct-manipulation control than tools like Keynote or PowerPoint
• Theme customization is more limited than fully custom slide design tools

• Notch Bar mode is currently in beta and only available on MacBooks with a notch, so Windows and external-display users don't get this positioning benefit.
• No free tier or trial is mentioned; the purchase is backed only by a 21-day refund policy.
• Each license covers just 2 floating devices, which may be limiting for users who work across multiple machines.
• Fully offline local model support is highlighted for Mac, and cloud speech models may still require an API key or internet connection.
