Pitch

Open Slide is a presentation framework built for AI coding agents. An agent describes a deck in natural language and writes React pages, while Open Slide provides a fixed 1920 × 1080 canvas, scaling, navigation, hot reload, presentation and presenter modes, and an in-browser inspector. Its agent skills support deck creation and slide authoring; the inspector records element comments as source markers that an agent can apply. The framework also manages images, video, fonts, and SVG logos, and exports decks as static HTML, PDF, or editable PPTX files. It is distributed as a pnpm/Turbo monorepo with an `@open-slide/cli` scaffolder and `@open-slide/core` runtime, and produces static builds deployable to standard static hosts. The repository is MIT-licensed.

Marp, the Markdown Presentation Ecosystem, is an open-source toolset for creating slide decks from Markdown. Its format is based on CommonMark, with horizontal rules separating slides, plus directives and extended syntax for images, mathematical typesetting, auto-scaling, and theming. The ecosystem includes Marp Core, Marp CLI, and a VS Code extension; it can export decks to HTML, PDF, and PowerPoint through Google Chrome or Chromium. Marp is built on the pluggable Marpit framework, and the official tools and related libraries are MIT-licensed.

OpenSlides is a free, open-source offline desktop application for creating animated code presentations. It turns source code into slides and converts selected lines into presentation steps, using Magic Move transitions to animate changes between code states and stepped highlights with configurable dimming, scaling, and transition timing. It provides light and dark themes, 16 syntax themes, slide search, thumbnails, keyboard navigation, full-screen playback, optional autoplay with per-slide timing, and project operations such as duplication, import, export, and drag-and-drop reordering. Built with Tauri and Svelte 5, it keeps projects on the local computer and provides installers for macOS, Windows, and Linux.

PowerPoint is a presentation format used in procurement work and cross-department communication.
