Dev builds PPTX Native, a Gemini Skill that generates fully editable .pptx decks
g7sid · reddit · 2026-10-18
The author complains about making slides with Gemini: Canvas mode only outputs Google Slides with locked elements and almost no design control, while HTML output is hard to customize and needs heavy cleanup.
So he built PPTX Native, a Gemini Skill: one prompt yields a researched, professionally designed .pptx with natively editable charts, tables, shapes and text. It self-checks slides for layout issues before delivery and can also edit existing decks.
Usage: download the zip from GitHub Releases, upload it directly in Gemini → Customize → Skills → Create → Upload (no extraction needed). It runs in Task mode (Pro/Ultra), works best with the Argon model, and isn't too usage-hungry.
