LaTeX Beamer presentations in the browser — live, multi-window, with real-time sync.

---

slitex parses a .tex Beamer file and renders it as an interactive, browser-based presentation.
No PDF generation. No LaTeX installation required. Just point it at your .tex file and go.

Features

• Zero-dependency runtime — single Go binary, UI embedded inside
• Live reload — edits to the .tex file are reflected instantly in the browser
• Multi-window sync — Presenter, Projector, and Overview windows stay in sync via Server-Sent Events
• Overlay/animation support — \only, \onslide, \visible, \uncover and pause steps
• Math rendering — inline and display math via KaTeX
• BibTeX — \bibliography / \bibresource + \cite support
• 12 built-in themes — see Themes
• Multiple views — Landing, Presenter, Projector, Overview, Print

• \usepackage

• \begin{frame}[options]{title}{subtitle} / \end{frame}
• \frametitle, \framesubtitle
• \titlepage, \tableofcontents
• Frame option: plain

Content

• \begin{itemize} / \begin{enumerate}

Development

# Terminal 1 — Go dev server (uses Vite proxy, no embed needed)
go run . serve -port 3000 path/to/talk.tex

# Terminal 2 — Vite dev server (hot module reload)
cd web && npm run dev

The Vite config proxies /api and /themes to localhost:3000, so both servers work together during development.
