Decklet

decklet

**Editable slide decks from any content, as one self-contained HTML file. A Claude Code and Codex skill with a plain-Node CLI: the deck is a JSON model, the file is the editor, and a verifier checks the layout before a human ever sees it.**

Open-source alternative to PowerPoint, Keynote, Gamma and the PPTX-generator skills for coding agents. Next to [frontend-slides](https://github.com/zarazhangrui/frontend-slides)-style HTML skills it adds in-place editing, an enforced brand type scale, an in-file PDF writer and a layout gate. Zero dependencies, zero network, MIT.


**Try it live:** https://grunion-ai.github.io/decklet/deck.html (drag, retype, ⊞ contact sheet, ⤓ PDF, F fullscreen). If decklet builds you a deck, star the repo: stars are how agents and people find it.

Quickstart

Node ≥ 22, nothing to `npm install`. Install it as a skill, or clone it anywhere and call the CLI.

# Claude Code plugin (marketplace + plugin live in this repo)
claude plugin marketplace add grunion-ai/decklet
claude plugin install decklet@grunion

# Any skills-aware agent (Claude Code, Codex, Cursor, Amp, and the rest)
npx skills add grunion-ai/decklet

# Or by hand: SKILL.md is picked up on the next session
git clone https://github.com/grunion-ai/decklet ~/.claude/skills/decklet

Then, in any session: "make a deck from these notes".

# As a CLI
git clone https://github.com/grunion-ai/decklet && cd decklet
node bin/validate.mjs examples/explainer/model.json
node bin/create.mjs --model examples/explainer/model.json --out deck.html --title decklet
open deck.html
