What is OpenDeck?

OpenDeck is a presentation tool. OpenDeck lets an AI agent build animated, narrated and interactive slide decks from a prompt, document or spreadsheet. Decks ship as one file or standalone HTML, using an open, free and open source format.

OpenDeck is a presentation tool that turns a topic, a document or a spreadsheet into a finished slide deck, with the work done by an AI agent instead of a person dragging boxes around a canvas. The agent decides the structure, writes the slides, adds motion and records a narration voice. The result is a deck that can deliver itself, even when nobody is in the room to present it. The workflow starts inside an agent environment. OpenDeck installs as a plugin or skill for tools such as Claude Code, Claude web, Claude desktop, Antigravity CLI, OpenCode and Codex. After a one-time install, the user asks for a deck in plain language, for example a quarterly report built from a sales spreadsheet. Ideas are revealed one beat at a time with animation, and a natural voice reads each slide. Slides can also include toggles, drag-to-reorder items and tap-to-reveal elements, so viewers can explore a point instead of only watching it pass. Everything lives in a single file: slides, motion and voice together. That file can be emailed, hosted or presented offline, with no account and no links that can break. Decks can be exported as a standalone HTML page that opens in any browser, or as a .deck file for the OpenDeck apps. The .deck format is open and in the public domain, the app is licensed under Apache-2.0 and the kit under MIT. Viewing works in a browser on any device, with apps listed for Mac, iPhone and iPad, and Windows, and an Android app marked as coming soon. OpenDeck suits educators, analysts, founders and teams who want self-running explainers, async briefings or interactive reports without hand-building slides. It differs from conventional slide editors by being agent-first and from video generators by keeping the output as an editable, inspectable open file. Three sample decks on the homepage show narration, interactivity and attention-guiding motion in practice.

How do you use OpenDeck?

  1. 1Open a sample deck
    Try one of the three example decks on the homepage to see narration, animation and interactivity in the OpenDeck web app before building anything.
    OpenDeck — Open a sample deck
  2. 2Add OpenDeck to your agent
    In Claude Code, run the plugin marketplace add and plugin install commands once. Other supported agents include Claude web and desktop, Antigravity CLI, OpenCode and Codex.
  3. 3Enable the skill on Claude web
    Turn on Code Execution and File Creation in Settings, then upload the skill ZIP under Skills and toggle OpenDeck on. This needs desktop web.
  4. 4Ask for your deck
    Use the /opendeck command and describe the talk, or point it at a document or spreadsheet, such as a Q3 report from a sales file.
  5. 5Open and present the result
    Load the generated .deck file in the OpenDeck web app or a native app, or export a standalone HTML page to share in any browser.
    OpenDeck — Open and present the result
  6. 6Explore the open format
    Read the .deck format specification if you want to build tools around decks or understand what the single file contains.
