Codex Slides is an open-source slide studio built for coding agents. Describe a deck, point it at a repo or a folder of files, and watch your local Codex research, outline, style, render, and export a presentation — every slide a full visual canvas, all of it visible and steerable, none of it a hidden background task.

Think of it as the open-source, agent-native alternative to Gamma and Tome — except it lives inside the coding agent you already use, runs on your existing codex login with zero extra API keys, and keeps every project on your own disk.

What you get, out of the box:

• 118 ready-made visual systems — 45 curated deck templates across 15 professional categories, plus 73 community styles across 12 groups (reports, infographics, diagrams, data & maps, dashboards, posters, product, brand, architecture, photography, editorial, illustration).
• 24 guided scenarios in 6 groups — zero-to-one decks, source-to-slides, data stories, deep research, redesign, localization, training, keynotes, and more.
• ⚡ Fast mode — renders every page in parallel (not one-by-one), so a 10+ slide deck lands in ~4–5 minutes while the outline and visual direction stay locked.
• Production export — real, presentation-ready PPTX and print-ready PDF with speaker notes preserved; 1K/2K/4K render quality and five aspect ratios (16:9, 4:3, 1:1, 9:16, 3:4).
• Zero extra keys — runs on your existing codex login; every project stays on your disk.

Open Codex Slides in the Codex Browser and keep it visible.

Then start a new Codex task: “Open Codex Slides and build me a 6-slide deck about …” — and watch it happen live.

Why Codex Slides

Most AI slide generators hide the process behind one request and return a file. Codex Slides treats the presentation as a persistent, inspectable project you own end to end.

Codex Slides is image-native: each slide is composed as a full visual canvas. That makes it strong for visual fidelity and rapid iteration. Exported PPTX files contain full-slide images rather than individually editable PowerPoint shapes.

How it works

Codex Slides keeps the entire chain live and steerable — from a rough idea to a finished, exportable deck.

Projects are written to disk throughout the workflow. Opening the same project from Codex and another browser stays synchronized; rendering pages refresh from the canonical project state, and interrupted generation can resume safely.

Everything happens in a live, Browser-first workspace — not a black box. Start from a prompt, a proven visual direction, or a purpose-built workflow, then stay in the same durable project through questions, research, outline, generation, editing, presenting, and export.

Examples

Every card below is a real visual system that ships with Codex Slides, paired with the exact prompt that turns it into a finished deck. Each prompt opens a durable project, stops for outline and visual-direction approval, then renders in the Browser where you watch it happen — swap in your own topic, audience, or files and go.
