In their own words
OpenDeck
OpenDeck is a free player for self-contained presentation documents in the `.deck` format. An AI agent can build a deck from a talk description, document, or spreadsheet, including its structure, slides, motion, and voice narration. Decks can also contain toggles, drag-to-reorder controls, and tap-to-reveal interactions. Users can export a `.deck` file for OpenDeck apps or a standalone HTML page. A `.deck` file includes what it needs for playback and can run offline without depending on a server. OpenDeck runs on iPhone, iPad, and Mac; exported HTML decks open in modern browsers on any device. The homepage lists browser and Windows apps as available and says Android is coming soon. Setup options are offered for Claude Code, Claude web, Claude desktop, Antigravity CLI, OpenCode, and Codex. OpenDeck is free forever with no in-app purchases. Its privacy policy says the app collects no personal data and makes no network requests, and that imported decks remain on the device. The app is Apache-2.0 licensed, its authoring kit is MIT licensed, and the `.deck` format is CC0 public domain.
