Live preview Markdown editor
Only for Mac
$5.99
Mac
Native Markdown editor with live preview, syntax highlighting, MathJax, Mermaid diagrams, and synced scrolling — on Mac, iPad, iPhone, and Vision Pro.
Foliom is a fast, native Markdown editor with a live HTML preview, built in Swift and SwiftUI for Mac, iPad, iPhone, and Apple Vision Pro.
Write in plain Markdown on the left, see the rendered document update instantly on the right. Foliom keeps the writing surface minimal and the preview rich, so you can focus on the words while still getting code blocks, math, diagrams, and a clean reading experience.
KEY FEATURES
• Live side-by-side preview with synchronized scrolling between editor and rendered output

PRIVACY
Foliom does not collect analytics and does not require an account. Your documents stay on your device and in the iCloud or local folders you choose.
Foliom is a love letter to MacDown, rebuilt from scratch in modern Swift for the current generation of Apple platforms.
