Worker tool: PowerPoint creator

TL;DR: Turn a Notion page into PowerPoint slides and export them as a ready-to-download .pptx presentation. The worker uses headings to organize slides, preserves common text formatting, and attaches the generated file to the source page as a comment.

Quickstart

This worker needs no external credentials. Notion authenticates each deployed agent call automatically.

From the repository root:

npm install --global ntn
cd workers/templates/powerpoint-creator
npm install
ntn login
ntn workers deploy --name powerpoint-creator

In Notion, add the deployed worker to a custom agent under Tools and access > Add connection.

Try asking

• "Create a PowerPoint presentation from this page."
• "Turn this project brief into PowerPoint slides and attach the .pptx file."
• "Export this meeting-notes page as a PowerPoint .pptx presentation."

The agent calls createPresentation, then adds the generated file to the source page as a comment.

How it works

1. Reads the page title and content via the Notion Markdown API
2. Parses the markdown into slides — headings start new slides, content underneath (paragraphs, bullets, numbered lists, to-dos, code, quotes) becomes slide body
3. Generates a .pptx file using pptxgenjs with Notion-inspired styling
4. Uploads the file via the Notion File Upload API and attaches it as a page comment

Project structure

src/
  index.ts          — Worker tool definition
  types.ts          — Slide and content types
  theme.ts          — Notion-inspired color and font theme
  notion.ts         — Notion API helpers (read page, parse markdown, upload file)
  presentation.ts   — pptxgenjs slide builder with slide masters

Run locally

Local execution needs a Notion internal integration token with access to the source page. Put NOTION_API_TOKEN=... in an untracked .env file, then run:

ntn workers exec createPresentation --local -d '{"pageId": "<your-page-id>"}'

Slide design

The presentation uses Notion-inspired styling defined via defineSlideMaster():

• Title slide — dark background with large title and accent line
• Section slide — warm gray background for headings without body content
• Content slide — white background with heading, divider, body area, footer bar, and slide numbers

Inline markdown formatting is preserved: **bold** renders as bold and *italic* renders as italic in the slides.
