What it does

  • Creates decks from scratch with pptxgenjs, plus a curated list of footguns that actually corrupt files (no # in hex colors, no 8-digit alpha hex, negative shadow offsets, outEnd labels on stacked charts, combo charts missing valAxes/catAxes).
  • Edits existing decks and templates by unzipping, patching ppt/slides/slideN.xml, and rezipping — with helper scripts to duplicate slides (add_slide.py), prune orphaned parts (clean.py), and render a labeled thumbnail grid for layout selection (thumbnail.py).
  • Reads content via markitdown so slide text can feed summaries, emails, or datasets.
  • Enforces QA: validate.py checks schema, relationships, content types, and chart XML (with --original baselining for template-derived decks), then PDF→JPEG rendering for a visual pass on overflow, overlap, and margins.
  • Guides design: ten ready-made palettes, LibreOffice-safe font list, type-size scale, and an explicit "avoid" list that bans AI-tell artifacts like title underlines and decorative accent stripes.

Who it's for

  • Consultants, founders, and PMs shipping pitch decks and reports regularly
  • Teams that must fill a corporate .potx template programmatically
  • Anyone extracting slide text in bulk for summarizing, translating, or analysis
  • Users comfortable with Python/Node tooling who want automated visual QA

Examples

  1. "Turn this markdown brief into a 12-slide pitch deck" — picks a topic-fitting palette, adds native charts, validates the file, and renders slide images for a final check.
  2. "Use layout 3 from template.potx for an 8-slide quarterly report" — thumbnail the template, duplicate slides, swap XML text, then run validate.py --original to catch regressions.
  3. "Pull the content from quarterly.pptx and draft an exec email" — markitdown dumps per-slide text that Claude then summarizes.
