The open-source AI slide studio that lives inside Codex.

Turn a prompt, a repo, or a pile of files into a beautiful, presentation-ready deck — without leaving your coding agent.

⚡ 10+ high-quality slides in ~4–5 minutes — Fast mode renders every page in parallel, not one by one

45 deck templates · 73 community styles · 24 guided scenarios → production-ready PPTX / PDF · Browser-first · zero separate API keys · web & desktop

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. Create a 12-slide market deck about 2026 humanoid robotics. Let me confirm the questions, outline, and visual direction before rendering.

Try it in 60 seconds

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

Writing about Codex Slides? Everything a creator or reporter needs — boilerplate, stats, comparisons, an FAQ, ready-to-post copy in English / 中文 / 日本語, a video script, and an asset manifest — is in the Media & creator kit. Paste it into your agent and it can write the video or article for you.

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.

Typical one-shot generator Codex Slides in Codex

Wait for a hidden end-to-end task Open the live product before work begins

Discover problems after export Confirm requirements, outline, and style first

Restart when the result is wrong Continue editing the same saved project

Re-upload context every time Keep Design Files and brand rules with the project

Rebuild a successful visual direction Save a project as a reusable visual-system template

Describe visual bugs in prose Mark directly on the slide

Separate app and agent histories Codex and the Browser operate one shared project

Bring your own API keys and billing Runs on your existing codex login, zero extra keys

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.

Codex conversation │ ▼ Open the Codex Slides home in the Codex Browser │ ▼ Create a durable project │ ├── Clarify the brief ├── Optional source-backed research ├── Review and revise the outline ├── Choose a visual direction ├── Watch slides render progressively └── Review the finished canvas │ ├── Chat edits and queued follow-ups ├── Add / duplicate / move / delete / transition ├── Mark-based slide edits ├── Design Files and @ references ├── Save as a reusable project template ├── Brand & Design System ├── Play mode └── PDF / PPTX export

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.

See it inside Codex

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.

1 · Start at Home — describe what you want to make, attach source files, choose the engine and output settings, or jump into a guided workflow.

2 · Explore Community Styles — browse 73 visual directions across reports, infographics, diagrams, data, UI, posters, products, brand systems, architecture, photography, editorial, and illustration. 3 · Pick a scenario — choose from 24 configured workflows for zero-to-one decks, source-to-slides, data stories, research, redesign, localization, training, keynotes, and more.

4 · Enter a durable project and clarify the brief — confirm audience, page count, aspect ratio, language, resolution, and visual intent before the outline begins.

5 · Research — run optional multi-round web research, then keep the Markdown brief and sources inspectable inside Design Files. 6 · Shape the outline — edit every title and talking point, add or remove slides, change the order, or ask the agent to revise the story.

7 · Lock the visual direction — Codex Slides ranks Community Styles against the topic and outline; choose one, search the full library, or keep the default. 8 · Generate progressively or in parallel — watch completed slides land in the canvas while remaining pages stay visible and resumable. Fast mode fans pages out in parallel and queues overflow.

9 · Edit in place — keep the complete slide in frame while you ask AI, mark a region, rewrite or redraw a page, add and reorder slides, set transitions, replace images, and prepare speaker notes. 10 · Present — start audience playback from any slide, or use Presenter Mode with a synchronized audience window, notes, navigation, and timer.

11 · Export — download a production-ready PowerPoint file or a print-ready PDF, with the project's speaker notes preserved.

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.

Business & market report — charts, KPI callouts, and a tidy consulting-grade grid. 📋 Copy the prompt Open Codex Slides in the Codex Browser and build a 12-slide market report on the 2026 humanoid-robotics market — size, CAGR, average selling price, and key takeaways — in a consulting-grade chart-and-KPI grid. Research first, then stop at the outline before rendering.

Data & dashboards — maps, donut and trend charts, and metric tiles. 📋 Copy the prompt Open Codex Slides and turn the attached dataset into a data dashboard on global EV-charging infrastructure — a world map of charging points, a regional donut, a growth trend line, and metric tiles. Analytical and dense. Confirm the outline first.

Product keynote — cinematic, high-contrast title moments for launches. 📋 Copy the prompt Open Codex Slides and create a cinematic product keynote — big high-contrast title moments, near-black slides with one glowing product hero and a single bold line per page. 16:9 at 4K. Show me the visual direction before generating.

Editorial — refined typography and a print-quality grid. 📋 Copy the prompt Open Codex Slides and design an editorial, magazine-style deck — a refined serif masthead, a strict multi-column print grid, warm photography, and generous white space. Use my essay as the source. Approve the outline, then export PDF.

Seed pitch — midnight & traction — a confident dark title system, one electric-blue accent. 📋 Copy the prompt Open Codex Slides in the Codex Browser and build a 10-slide seed pitch for a developer-tools startup — problem, insight, product, demo, traction, market, model, moat, team, ask. Use a confident dark "midnight" title system with one electric-blue accent. Stop at the outline, then render in Fast mode.

Product keynote — clean daylight — a bright, airy layout with soft 3D diagram nodes. 📋 Copy the prompt Open Codex Slides and create a 14-slide product keynote for an agent-native platform. Bright, airy "daylight" layout with soft 3D diagram nodes and one indigo accent, one idea per slide. Show me the visual-direction options, then generate at 4K.

Answer-first data story — leads with the headline, then a map and trends. 📋 Copy the prompt Open Codex Slides in the Browser and turn the attached dataset into a 9-slide data story that leads with the answer: a headline metric, a national map of where it's happening, trend and regional breakdowns, and a recommendation. Analytical and uncluttered. Confirm the outline first.

Editorial report — refined serif headlines and a strict print grid. 📋 Copy the prompt Open Codex Slides. Use the attached PDF as the content source and rebuild it as a 12-slide editorial report — refined serif headlines, an ink-and-paper craft palette, and a strict print grid. Keep every fact, add nothing. Stop for outline approval, then export PPTX and PDF.

Liquid Glass bento dashboard — transparent glass cards over a soft blurred ground. 📋 Copy the prompt Open Codex Slides and build a 6-slide product overview in the Liquid Glass Bento style — an asymmetric bento grid of transparent glass cards over a soft blurred ground, one hero cell plus titled metric tiles.
