Introduction

DexCode is an AI-first slide authoring and refinement tool for developers who never want to leave their terminal.

What is DexCode?

DexCode is an open-source slide authoring tool designed for developers. Instead of switching to PowerPoint or Google Slides, you create and refine presentations directly from your terminal using AI coding agents like Claude Code, Codex CLI, Gemini CLI, or Cursor.

Slides are written as MDX files — Markdown with React components — and rendered in real-time with hot module replacement. Every change you make (or your AI agent makes) is reflected instantly in the browser.

Key Concepts

  • Zero Context Switching: The AI agent you already use for coding — Claude Code, Codex, Gemini CLI, Cursor — builds your slides too. Same terminal, same flow.
  • Per-Slide Parallel Editing: After the initial draft, run one agent per slide and push multiple revisions at once instead of serial rework.
  • AI Micro-Tuning: Delegate spacing, wording, chart labels, and visual polish to AI for high-quality finishing touches with precision prompts.
  • Live Preview: Hot Module Replacement (HMR) keeps your browser preview in sync as files change — every save is reflected instantly.
  • 100+ Built-in Templates: Charts, code blocks, layouts, dashboards, and more — all production-ready out of the box.
  • Two Image Generation Skills: Generate photorealistic images via Gemini API and professional SVG diagrams directly from the CLI — both auto-styled to your deck's theme.
  • Shareable: Use Cloudflare Tunnel to share a live URL with your team, export to PDF/PPTX, or present with built-in presenter mode.
  • 14 Agent Skills: Specialized Claude Code skills for deck design, scaffolding, image generation, video export, localization, quality assurance, and more.

Who is DexCode For?

DexCode is built for:

  • Developers who create sprint reviews, technical presentations, or pitch decks
  • Teams that use AI coding agents in their daily workflow
  • Anyone who wants to stay in their terminal and avoid context switching

How It Works

  1. Prompt Between Commits — Tell your AI agent to create slides while coding. Point it at your project path and it reads context automatically.
  2. AI Generates Your Deck — The agent creates MDX files and your slides appear in the browser in real time with hot reload.
  3. Revise from the Terminal — Refine your deck with natural language prompts, using the same workflow as code changes. Edit multiple slides in parallel.
  4. Present & Share Instantly — Jump into presenter mode, export to PDF/PPTX, or share a live URL via Cloudflare Tunnel.
