Scientific slides, without surrendering the canvas
Quarkfoil combines readable Markdown and LaTeX with the direct manipulation of a slide editor. Build structured layouts quickly, then place and tune the objects that need individual attention.
Structured when useful
Choose one-, two-, or three-region layouts, opening pages, title-only slides, or a completely free canvas.
Precise when needed
Move and resize text, equations, and images visually. Adjust crop, focus, alignment, layer order, and relative type size from the properties panel.
Portable by design
The presentation remains a Markdown file plus its figures. Quarkfoil runs locally, vendors its browser libraries, and needs neither Node nor a cloud account.
One source, three views
Source, Design, and Present all operate on the same document. Simple slides can be written directly; graphical changes are serialized back into readable Markdown annotations.
Start with the example
The repository includes a presentation demonstrating every layout, image
behavior, equation overlays, and annotations. View the exported example
in presentation mode, or open it with uv run quarkfoil example/deck.md
from a source checkout.
A deliberately small toolchain
Quarkfoil uses a Python standard-library server and pinned local copies of Reveal.js, KaTeX, Marked, and js-yaml. Presentation editing never depends on a runtime CDN. Read the security model and the complete licensing inventory.
