Show HN: Tycoslide – Editable PowerPoint Slides from Markdown and TS

I created this to help automate my day-today as a product marketer. I create lots of slides for clients (training, competitive battlecards, value props) which need to be in their brand and design system, and I wanted a way of doing that from Claude Code. I love Marp and Slidev and originally got pretty far with them. But since my clients need editable deliverables, they couldn't work for me.

tycoslide is similar to other markdown-to-slides tools, but it produces editable PowerPoint files instead of PDFs and HTML. It uses HTML, CSS and Playwright to measure the layout, then rebuilds it as native PowerPoint objects.

Everything is TypeScript, so you can build custom components and layouts without CSS. I had the W3C DTCG standard in mind for design tokens, so it should be pretty flexible. A key design goal is build-time validation, so it fails fast and loud to catch things like layout overflows, missing tokens, and invalid parameters.

Themes are just npm packages containing your graphics files, design tokens, color palette, components, and layouts. You can then use markdown to create your slides. There's an example theme and showcase presentation in the repo too.

This is the first release, so looking for feedback on the DX, slide authoring workflow and what's missing. Hope this is helpful!
