kadalcc/deck

Build it. Rehearse it. Own the room.
Kadal Deck has your back from the first idea to the last applause: AI that drafts with you,
rehearsal with a voice and a timeline, a teleprompter and your phone as the clicker, and a live
room that keeps every seat in it — polls, quizzes, Q&A and reactions.
A talk is more than its slides. You need an outline that holds, slides that look the part, a few
run-throughs out loud, the right notes in front of you on the day, and a room that stays with you
to the end. Kadal Deck is built for all of it. You write the deck in one deck.mdx file, with AI
beside you if you want it; you rehearse it with the deck reading your notes and keeping time; you
present it with your phone in your hand; and the audience joins from theirs to vote, ask and react.
The engine is open source, and hosting is free for public decks.

## Build it
Start from an idea, not a blank slide.
✦ An AI assistant that drafts with you. In the builder on deck.kadal.cc,
tell it about the talk ("turn my notes into eight slides", "add a poll after the intro") and it
writes and revises the deck slide by slide, checks its work against the compiler, and answers
the comments on your draft. Every change is a revision you can undo. It runs on your own key
from OpenAI, Anthropic, Google or OpenRouter.
✦ Your own agent, too. The Agent Skill and the MCP server teach Claude
Code, Cursor, VS Code or any MCP client the format, then let it outline, write slides, lint them,
render them to look at its own work, and fix what it sees. The hosted MCP server brings your
published decks to Claude, ChatGPT and Cursor.
Write where you like. Markdown and MDX in your editor, with the VS Code extension
and the kadal-deck CLI, or in the browser builder: edit right on the slide, and drop in emoji,
icons, stickers, shapes, free photos, GIFs and memes from the media panel.
Look the part. 16 themes in light and dark, 28 built-in backgrounds, and the
Pro library of 95 backgrounds and layouts.
## Rehearse it
Practise out loud until it's yours.
The deck reads your notes aloud and turns its own pages as it goes, in the browser's voice
or the Kokoro AI voice running in your browser. Narration
shows every chapter and slide on a timeline, so you hear how long the talk really runs.
A plan for every slide. Give each slide a time; the timer's bar marks where you should be,
and a pacing badge says how far ahead or behind you are, so you find the long parts before the day.
A teleprompter and the presenter view. Your notes, big, on the screen you read from, following
each click; and beside the slide, the notes, the next slide and the timer.
✦ Copilot can quiz you on your notes while you rehearse a hosted deck.
Glossary cards. The first mention of a term links to its definition,
so you, and later the room, never lose the thread.
## Present it
Walk on stage with everything at your fingertips.
The presenter view: notes that highlight with each click, the next step, a timer with pacing and every tool on one screen. Press S in any deck.
