What is Codeck?

Codeck is a native macOS app built in Swift for crafting Markdown presentations tailored to teaching and demoing Codex prompting workflows. You write slides separated by --- lines, add YAML frontmatter for themes and default Codex settings like model or sandbox, and embed fenced `codex` blocks to run live AI prompts directly in slides. It handles streaming responses as rendered Markdown, with run/stop buttons per block and full-screen playback via arrow keys.

Why is it gaining traction?

Unlike generic Markdown tools or web-based codecks apps, Codeck runs Codex CLI sessions natively over stdio, streaming live outputs into slides without leaving the app—ideal for interactive demos. The split-view editor with live preview, multiple themes, and per-slide run-all buttons make iterating on prompts feel seamless on macOS native UI. Devs dig the document-based .mdeck format that overrides system Markdown editors.

Who should use this?

MacOS devs running Codex workshops or internal training on prompting tactics, like AI engineers at codec basel firms building live codecheck decks. Prompt educators tired of static slides who want to demo refactor goals or reasoning efforts in real-time. Teams using CodexModelCatalog for model selection in teaching flows.

Verdict

Grab it if you're on macOS and need a polished native app for Codex presentations—solid tests and docs for an early project, but with just 17 stars and 1.0% credibility score, treat as alpha for production decks. Run the build script to test locally before committing.
