OpenDeck

OpenDeck is a free, open-source presentation tool that turns a description, document, or spreadsheet into a fully animated, narrated slide deck. Instead of dragging boxes around a canvas, you tell an AI agent what you want to present — or hand over a file — and it builds the structure, slides, motion, and voice for you. The result is a single .deck file that contains everything: slides, animations, and narration, all in one portable package.

What makes OpenDeck stand out is how it handles the hard parts of presenting. Every deck gets a natural voice that reads each slide, so your presentation works even when you're not in the room. Ideas appear one beat at a time with built-in pacing, and viewers can interact with toggles, drag-to-reorder, and tap-to-reveal elements. You can export a standalone HTML page that anyone can open in a browser, or keep the .deck format for the OpenDeck apps. No account, no links to break, no lock-in.

OpenDeck is ideal for educators, business professionals, and anyone who needs to create clear, engaging presentations quickly. Use it to turn a quarterly report into a narrated walkthrough, build an interactive lesson that students can explore at their own pace, or share a self-contained pitch deck that works offline. The tool is free forever with no in-app purchases, and the code is open source under Apache-2.0.
