What it does

The plugin adds a set of skills to Codex for building presentations: topic research, outline, style choice, slide rendering, edits and export. Each slide is treated as a full visual canvas rather than text in a template. It has a fast mode that renders pages in parallel, a local preview in the browser and a desktop app, and export to PDF and PPTX. Projects are stored locally and it runs without external API keys.

Who it is for. For anyone building presentations in Codex: marketers, designers, product managers and speakers.

Good fit when

  • You want to build a deck from a topic or brief inside Codex
  • You want slides as visual canvases rather than text in a template
  • You need to export a finished deck to PDF or PPTX

Not a fit when

  • You do not work in Codex and will not install it
  • You need a plain Markdown outline without slide layout

Example request

Build a 10-slide deck about a product launch, then show a preview and export it to PDF

Limitations

The plugin targets Codex and needs a ChatGPT account, which is not reachable from Russia without a VPN. Local development runs a web service and a desktop app via pnpm and needs Node. Export and preview run locally.

How to disable. Remove the plugin with codex plugin remove codex-slides@codex-slides.

README in short

The README describes Codex Slides as an open slide studio inside Codex, with the chain from research and outline to style, render, edits and export visible as it runs. It installs via codex plugin marketplace add and codex plugin add, with separate local development on pnpm using a web service and an Electron app. It bundles scenarios, templates and styles, plus a CLI and MCP interface. It states no API keys and on-disk project storage. MIT licensed.

FAQ

Do I need paid API keys?

No. The slide engine runs without external keys and stores everything locally. You only need Codex itself.

To PDF and PPTX, with a local preview in the browser or desktop app before export.
