MarpUI

MarpUI is a native iPadOS presentation editor powered by Marp. Write your slides in Markdown, see them rendered in real-time, and present directly from your iPad. **Write slides effortlessly** The split-pane editor gives you a Markdown editor on the left and a live slide preview on the right. Use the Insert and Blocks menus to quickly add headings, formatting, lists, tables, code blocks, blockquotes, and more. Keyboard shortcuts like Cmd+B (bold) and Cmd+I (italic) keep you in the flow. **Rich Markdown extensions** Go beyond basic Markdown with subscript, superscript, highlights, strikethrough, footnotes, task lists, and GitHub-style alerts. Add Mermaid diagrams for flowcharts and sequence diagrams. Write math equations with KaTeX. Syntax highlighting supports 190+ programming languages. **Beautiful themes** Choose from built-in Marp themes or import your own custom CSS themes. Edit themes live with instant preview. Set fonts per slide or for the entire deck. **Present like a pro** Three presentation modes to suit any scenario: - Fullscreen slideshow with tap, swipe, and keyboard navigation - Presenter view with current slide, next slide preview, speaker notes, and a timer - External display mode: connect a USB-C HDMI adapter to show slides on a projector while your iPad shows the presenter view **Images with power** Insert images from your Photos library with one tap. Apply sizing, filters (blur, brightness, grayscale, sepia, and more), and background modes. Use split-screen backgrounds for striking visual layouts. **Export and share** Export your presentations as self-contained HTML files or PDF documents. Share via AirDrop, email, or any app on your iPad. **Sync with iCloud** Link your iCloud Drive MarpUI folder to access the same decks on your iPad and Mac. Changes sync automatically. Conflict detection alerts you when a file has been modified on another device. **Fully offline** MarpUI runs entirely on your device. No account required, no data uploaded, no internet needed after installation.
