What it makes

Pages from the decks in examples/, rendered by the engine. In the exported file every bar, label, and card is a native PowerPoint shape with editable text. Three of the decks come ready to open: product pitch · charts · quarterly review, in Chinese.

Talk to us

Issues are welcome any time. Open one, or follow @liustack on X. Share what you made with pptwise, which harness you use, and what the next release should solve. New releases land there first.

Highlights

⚡ Tell your AI what to cover, get the deck. You bring the intent, the engine turns semantic page kinds and typed components into a coherent theme-bound deck. The same bound input renders the same output every time.

✏️ Open it in PowerPoint and keep working. Every heading, bullet, and chart bar opens in PowerPoint for you to retype and restyle. Chart and table figures are the exception: every bar and cell is an editable shape with editable text, not a native PowerPoint chart or table object carrying data, so to change the numbers, have your AI rebuild that page. Start from 24 factory themes, copy one into your workspace, or extract colors and fonts from a deck your company already uses.

🔌 Installs into the agent you already use. One command puts pptwise into DeepSeek Harness, Claude Code, or any agent that reads a skill folder (Codex and friends), and it knows how to build a deck the moment it lands.

🔁 Revisions without describing everything again. One command opens a live preview in your browser. Tell your AI what to change in plain words, and the page refreshes itself as each revision lands.

🔒 No account, no API key to render, no network at render time. Install it and it works. Node 22.19+ or Bun is all you need on the machine. Optional stock-photo search uses the user's own Pexels key.

Install

Step 1, hand it to your AI. Send it this line:

Install pptwise following https://raw.githubusercontent.com/liustack/pptwise/main/INSTALL.md, then run the health check and tell me the result.

On DeepSeek Harness, send this instead. There pptwise is a native plugin rather than a skill folder, so it has its own guide. You pick the line, not your agent: an agent cannot reliably tell which harness it is running in.

Install pptwise following https://raw.githubusercontent.com/liustack/pptwise/main/INSTALL-dsh.md, then run the health check and tell me the result.

There is no step 2. Your AI puts the skill folder where your harness reads it, and the skill brings its own version-pinned launcher, so there is no CLI to install by hand. pptwise renders a PPTX entirely locally: no API key, no account, nothing to configure for render. Optional stock-photo search needs the user's own Pexels key. The only prerequisite is Node 22.19+ (or Bun).

Quick start

IR v5 is one JSON file describing a complete bound deck. Every content page names its semantic kind. The theme menu turns that kind into a visual face.

{
  "version": "5",
  "filename": "hello.pptx",
  "theme": { "id": "brief" },
  "slides": [
    {
      "type": "cover",
      "heading": "Hello pptwise",
      "subheading": "A first native deck"
    },
    {
      "type": "content",
      "kind": "points",
      "heading": "Why it works",
      "components": [
        {
          "type": "bullets",
          "items": ["Semantic IR in", "Theme-menu lookup", "Native DrawingML out"]
        }
      ]
    },
    { "type": "ending", "heading": "Thanks" }
  ]
}

Save that as deck.json, then run:

pptwise validate deck.json
pptwise render deck.json -o out/hello.pptx
pptwise preview deck.json -o out/review --html

Choose a theme from pptwise themes --json by matching occasions and identity. Compare two to four candidates before binding:

pptwise theme try brief,swiss,memo

Create a complete independent v2 theme by copying a preset, forking a palette, or extracting an Office brand:

pptwise theme new --from brief -o themes/acme.theme.json --id acme
pptwise theme fork acme --primary "#0B5FFF" -o themes/acme-blue.theme.json --id acme-blue
pptwise brand extract corp.pptx -o themes/acme-brand.theme.json --id acme-brand --from brief

A deck project binds one theme in deck.spec.json, then keeps page content in pages/<id>.json. Render has no temporary theme switch. A same-menu color fork can replace the binding. A different menu requires returning to theme selection, then revisiting the spec and affected page fills.

No install also works: npx -y @liustack/pptwise validate deck.json. In a source checkout, use node dist/cli.js in place of pptwise. Ready-made v5 files live under examples/.

The commands you will reach for most:

command	purpose
spec validate <spec.json>	Validate page order, kinds, headings, narrative, and theme-menu fit.
assemble <dir>	Combine a deck project into derived IR v5 without storing rendering choices.
validate <target>	Check IR, binding, menu, components, assets, and content quality.
render <target> [-o <out.pptx>]	Render native editable PPTX.
audit <target>	Check geometry, contrast, truncation, dropped content, and monotony.
preview <target> [--html]	Write SVG pages and an optional self-contained review file.
serve <target>	Start a live review that reloads on source changes.
themes [--json]	List factory themes with occasion and identity metadata.
theme try <id,id,...>	Compare the fixed sample across two to four themes.
theme new, theme fork	Copy a complete theme or create a full-palette fork.
doctor	Check runtime, skill copies, optional capabilities, and a self-test render.
