ExtraSlides

Slides for technical talks

Equations in LaTeX, diagrams, code and D3 charts on the same slide — or on an infinite canvas when a slide is too small. Opens PowerPoint files and exports back to them.

Open ExtraSlides Free in your browser. No account, nothing to install.
The ExtraSlides editor: a slide with the attention equation typeset beside a D3 heatmap of attention weights.
Explanations that unfold. Code highlights line by line and D3 charts animate as you present.

See it work

An infinite canvas. Start with a whiteboard instead of a slide: shapes, connectors that stay attached, sticky notes and ink.
Pick up where you left off. Every deck and canvas saves as you work and waits in your library. ExtraSlides Pro syncs them across your devices, with cloud backups.
LaTeX, typeset as you type. Equations render while you write them. Full LaTeX and TikZ are there when KaTeX is not enough.
Style anything with Tailwind. Pick a theme, or give any object utility classes and plain CSS.
Over 2,000 icons. Search the open-source Lucide set and drop icons onto a slide; they take the theme's colour.
A slide of highlighted Python beside a line chart of validation loss.
Code and data. Highlighted code beside charts you edit as a table, or write in D3.
