What HTMLSlides is
HTMLSlides combines a skill for creating HTML presentations with a desktop app for presenting them. The skill generates decks from prompts or documents, and can convert PowerPoint files to HTML as well as HTML presentations from formats such as reveal.js, Marp, Slidev and Google Slides exports. Presentations are delivered as single HTML files with inline CSS and JavaScript, without a build step or dependencies. The skill includes 12 interactive component types, including charts, timelines, flip cards, code blocks and image grids, and works with AI agents such as Claude Code, GitHub Copilot, Gemini CLI, Cursor, Windsurf, Codex and Aider. The desktop app opens and presents HTML slides, with dual-display mode, speaker notes, a timer, laser pointer, thumbnail navigation and a synchronized audience view. It is designed for screen-sharing through Zoom, Teams and Meet. The app is available for web, Windows and macOS. The maker says presentations and notes stay locally in the desktop app, which has no telemetry, analytics or tracking; its presenter works offline and syncs views over a local WebSocket connection. The skill and basic app are free. App Pro is shown as a one-time purchase, with the pricing page listing both a $9 launch offer and $14.99; Pro adds annotation and audio recording tools.
