Slidekick
Your slide sidekick · Free & open source · Claude Code · Codex · Antigravity · Cursor
An agent skill that turns your brief, docs, data or repo into a native, on-brand PowerPoint deck. It edits the decks you already have without breaking them, and reviews any deck like a design director. Every build is checked in real PowerPoint before you see it.
> /plugin install slidekick@slidekick
Docs, a spreadsheet, a website, a repo, or a sentence. You get a story, slides with one idea each, and a .pptx on your brand that you can keep editing like one you made yourself.
“make a 10-slide seed pitch from this repo”
Update numbers, charts and tables, rewrite headlines, swap images, reorder or import slides. Masters, fonts and every slide you didn't mention stay exactly as they were.
“update the Q3 numbers to Q4 and keep the rest”
Real renders, an outline, mechanical issues like overflow, tiny text and low contrast, a story critique, and a scored design review with exact fixes. Works on .pptx, .ppt, .odp and .pdf.
“review this deck before Friday”
Every example ships with its brief, plan, canvas, QA report and design review, and rebuilds from its own folder.
/slidekick pixel-diffs it against the design and reads back what PowerPoint parsed. Problems get fixed before you open it./plugin marketplace add aarshx05/slidekick /plugin install slidekick@slidekick
Then just ask: “/slidekick make a deck about …”

Needs Python 3.10+ and Edge or Chrome. PowerPoint is optional but recommended for ground-truth QA (Windows, or Mac in beta). Without it, LibreOffice gives an approximate check.
Yes. Headlines are text boxes, bullets are real bullets, and charts are native charts with their data in an embedded workbook that you can open from PowerPoint. Transitions and animations are PowerPoint's own. Images are used only for photos and screenshots.
No. Without PowerPoint, /slidekick uses LibreOffice to check its work, which is a close approximation. With PowerPoint on Windows you get ground-truth QA, including readback of transitions and animations. PowerPoint for Mac is supported in beta for render checks.
Give it whatever you have: logos, a palette, fonts, a .potx or .pptx template, design tokens or a guidelines PDF. It builds on your template's masters and theme. No kit? It can take the identity from your website or product.
Yes. Edit mode reads the deck first, then changes only what you asked for, in place. Untouched slides, masters and fonts stay as they were, and the result is re-rendered to catch any text that no longer fits.
No. The pipeline runs locally. It goes online only to install its Python packages on first run, to fetch a Google Font you ask for, or to capture a URL you give it.
An ordinary 8-slide deck takes about 13 minutes: planning, four builds checked in PowerPoint, and two fresh-eyes review rounds. That's about 150k tokens of agent work on Claude Opus 5.5. Fixing a couple of numbers afterwards takes about 2 minutes.
Nothing. Slidekick is MIT-licensed. You use it with the agent you already have.
